Description
Technical Field
The invention relates to the technical field of data display, in particular to a CAVE display system and a CAVE display method adopting an LED3D screen.
Background
The CAVE system can be applied to any virtual simulation application field with immersion requirements. For example, virtual design and manufacturing, virtual demonstration, collaborative planning, etc., are widely used. In most existing CAVE systems, the walls of the virtual display space are usually composed of rear projection walls. Besides the rear projection, the display of the ground part can be provided with a projector above the display space to project on the ground. With the development of technology, technology for replacing projection display by an LCD 3D tiled screen or a large-sized LCD 3D screen has also appeared. But there is still a lack of ways to use LED3D screens as CAVE system displays.
Two common CAVE systems are known in the art.
CAVE system based on rear projection wall
The virtual display space of the CAVE system consists of more than 3 (including 3) hard rear projection walls. The system utilizes a multi-channel view synchronization technology to display the whole three-dimensional scene content on a projection wall. The user station is in the virtual display space, and wears 3D glasses for watching the three-dimensional imaging of the shadow wall, wherein the 3D glasses are attached with infrared mark points. And infrared cameras are respectively placed at the corners of the virtual display space. The distance between the position of the infrared mark point on the 3D glasses and the position of the eyes of the user is not large, so that the specification of the whole system is compared and can be ignored, and the system acquires the position parameter of the infrared mark point by using the infrared camera so as to acquire the position parameter of the eyes of the user. The system adjusts the shadow wall image to match the current position watched by the user according to the obtained parameters of the positions of the human eyes of the user (for example, a picture close to the shadow wall is enlarged, and a picture far away from the shadow wall is reduced). And the frame at the corner is calibrated by combining the frame calibration system, so that the displayed image cannot be distorted.
(II) CAVE system based on LCD 3D spliced screen or large-size LCD screen
The technical principle and the technology (one) are basically consistent, but the virtual display space is formed by replacing a rear projection wall with an LCD 3D spliced screen or a large-size LCD screen (except a ground screen), and is changed to display a matched rendering channel and a splicing processor.
However, the CAVE systems of the prior art have the following disadvantages:
in the technology I, a CAVE system with a virtual display formed by a rear projection wall needs to be seen clearly in a dark environment, and the requirement on ambient light is high. Moreover, the color saturation of the displayed picture is not high, and the viewing effect is not good. The projector has a short life.
In the technology (II), although the CAVE system based on the LCD 3D spliced screen or the large-size LCD screen does not need to have too high requirement on ambient light compared with a rear projection wall, and the color saturation is higher, the brightness and the color attenuation between units are inconsistent and can not be restored after long-term use. In addition, physical seams exist among the LCD screens, so that the watching effect is influenced. Large-sized LCD screens also have the problem of poor transportation.
With the improvement of display screen manufacturing technology, LED3D display screens have appeared. The LED3D display screen self-emits light and is not limited by ambient light; the color saturation of the display picture is high, the splicing among the display screens is seamless, and the service life is long. If the method can be applied to the CAVE system, the limitation of displaying various terminals in the conventional CAVE system can be greatly reduced.

Detailed Description
< architecture of the System of the present invention >
The 3D glasses mainly achieve a 3D effect by improving a quick refresh rate (usually reaching 120Hz) of a picture, belong to an active 3D technology, and are also called a time division shading technology or a liquid crystal time division technology. When 3D signals are input to a display device (such as a display, a projector, etc.), images are generated alternately in left and right frames in a frame sequence format, the frame signals are transmitted out through an infrared transmitter, a bluetooth, etc. in a wireless manner, the received 3D glasses are in charge of refreshing and synchronously viewing corresponding images by left and right eyes, the same frame number as a 2D video is kept, two eyes of a viewer see different rapidly switched images, illusions (the effect that the camera cannot shoot) are generated in the brain, and stereoscopic images are viewed.
As shown in fig. 1, the virtual display space of the present invention is composed of four LED3D display screens, and the LED3D display screens have the following characteristics: self-luminescence and no limitation of ambient light; the color saturation of the display picture is high, the splicing among the display screens is seamless, and the service life is long. A plurality of infrared cameras are arranged at the spatial corners of the LED3D display screen; the number of the cameras can be at least 3 to a plurality of cameras, and is determined according to specific requirements, and preferably, the number of the cameras is eight. A plurality of infrared mark points are attached to the 3D glasses. Every pair of 3D glasses has two left and right lenses, and the 3D glasses can realize opening and closing left and right 3D glasses lens respectively according to the external signal of receiving to the realization is switched on and off the alternative of left and right lens. In addition, four independent three-dimensional channel rendering servers, a multi-channel control server, an IR transmitter, a dynamic capture computer, an infrared tracking system and a network switch are needed. The multi-channel control server is used for receiving position information of two eyes of a user, generating picture control signals for controlling the four LED3D display screens according to the position information, and sending the four picture control signals to the four channel rendering servers so as to control the display of the four LED3D display screens respectively. The IR emitter is placed above a display space formed by the LED3D display screen, is connected with the multichannel control server and receives the synchronous signals sent by the multichannel control server. The IR emitter receives a synchronous signal sent by the multi-channel control server, and emits an infrared signal according to the synchronous signal, and the 3D glasses control the switching frequency of the left and right lens switches of the 3D glasses according to the infrared signal sent by the IR emitter so as to be consistent with the frequency of the picture images alternately displayed on the LED3D display screen. It should be noted that the IR transmitter is only one preferred embodiment, and in practical applications, a signal transmitter for bluetooth or high-frequency wireless signal communication may be used to wirelessly communicate with the 3D glasses, so as to control the frequency of switching the left and right lenses of the 3D glasses.
The moving capture computer obtains the position parameters of the infrared mark points on the 3D glasses obtained by a plurality of infrared cameras (preferably eight) through a network switch, thereby indirectly obtaining the position parameters of the eyes of the user. Two fixed-distance mark points, such as infrared LEDs, are arranged on the glasses frame of each 3D glasses. In the image obtained by the infrared camera, the infrared LED is the brightest point in most cases, and the LED position can be separated from the background by taking a proper threshold value. The acquired position of the LED in the image reflects the horizontal angle of the user relative to the camera and the height of the user, and the distance between the two LEDs reflects the distance from the user to the camera. In this way, it is equivalent to obtaining the user coordinates in the cylindrical coordinate system with the camera as the origin. The absolute coordinates of the user can be obtained by combining the position coordinates of the camera and through simple coordinate system transformation. Because the visual angle of a single infrared camera is limited, the task of capturing at 360-degree positions cannot be completed, and a plurality of infrared cameras can be used for splicing the visual fields. And a ring-shaped camera can be used, so that the task of capturing at 360-degree positions can be realized by one camera, and the principle is the same as that of the infrared camera. And transmitting the position parameter information of the two eyes of the user to the four-channel rendering server and the multi-channel control server through the switch by utilizing a MotiveTracker in the computer. The multi-channel control server and the dynamic capture computer can be integrated in the same computer, and the functions of the multi-channel control server and the dynamic capture computer can be realized by different computers respectively.
The picture image displayed on the LED3D screen is actually composed of two sets of pictures obtained by two virtual cameras in a virtual environment in the CAVE system simulating the left and right eyes of a human shooting an existing material. The CAVE system uses a multi-camera infrared positioning system to read the position parameters of the two eyes of the user by shooting the infrared mark points attached to the 3D glasses, so as to calculate the position parameters of the two cameras (the two virtual cameras simulate the positions of the left and right lenses of the 3D glasses) in the virtual environment in the system, thereby obtaining two groups of images in the display space for respectively displaying on the four LED3D display screens. Each 3D glasses is provided with two mark points with fixed distance for an infrared tracking system to capture the position. The CAVE system then adjusts the images in the display space to match the current position viewed by the user (e.g., a near image to the display screen is enlarged and a far image from the display screen is reduced) according to the change of the positions of the two eyes of the user. And the frame at the corner is calibrated by combining the frame calibration system, so that the display space image cannot be distorted. Wherein the display space image is output for display by four separate three-dimensional rendering services. The CAVE system displays two groups of calibrated pictures on the LED3D display screen continuously and alternately. Meanwhile, the 3D glasses cooperate with the continuously and alternately displayed picture images to switch the left and right lenses: when a left eye picture appears, a left eyeglass of the 3D glasses is opened, and a right eyeglass of the 3D glasses is closed; and when the right eye picture appears, the right lens of the 3D glasses is opened, and the left lens of the 3D glasses is closed. In order to synchronize the switching of the left and right eye pictures and the switching of the 3D glasses lenses, an IR emitter is placed above the display space, and is connected with a multi-channel control server and the 3D glasses for matching use.
Each lens of the 3D glasses comprises a liquid crystal layer, which can be blackened (transmittance is decreased) when a certain voltage is applied. Otherwise, it is similar to a normal lens without an additional voltage. Because the 3D image of each frame includes two pictures shot at different angles, the viewer can see the 3D image only when the left picture passes through the left lens (no fixed voltage is loaded on the lens) and the right picture passes through the right lens.
In addition, the 3D glasses should have a super high frame frequency to match the frame frequency of the high-speed projector, and can be implemented by the ferroelectric liquid crystal at a low frequency, such as several hundred Hz, and if there are more users, the high-speed modulation can be implemented by two ferroelectric liquid crystal panels in a cascade manner. In this case, the eyeglass lens is in the open state only when the front and rear liquid crystal panels are in the open state, and the entire eyeglass lens is in the closed state only when one liquid crystal panel is in the closed state.
A synchronization signal is required to control the alternation of the left and right lenses and the alternation of the left and right pictures to be consistent. Typically, infrared light is used to transmit this synchronization signal. However, due to the existence of adverse factors such as susceptibility to interference of fluorescent lamps and limited communication range, 3D shutter glasses using bluetooth and high-frequency wireless signal communication have also been developed. Under the control of a synchronous signal, voltages loaded on the left lens and the right lens are changed alternately, and then the brain synthesizes the two images into a whole to realize a 3D visual effect.
The principle of the 3D technology is implemented according to the refreshing time of human eyes to the image frequency, so that the human does not generate a motion feeling to the image by increasing the fast refreshing rate of the picture (generally, 120Hz is required) and the fast refreshing of the left eye and the right eye at 60Hz respectively, and the same frame number as that of the 2D video is maintained.
The glasses are essentially two liquid crystal screens which can be controlled to be turned on/off respectively, the liquid crystal layer in the glasses has two states of black and white, and the liquid crystal layer is normally displayed in a white state, namely a transparent state, and becomes black after being electrified. And the 3D glasses and the screen are accurately synchronized through the IR transmitter. The left and right eye pictures can be played alternately on the display screen, when the left picture is played, the left glasses are opened, the right glasses are closed, the left eye of a viewer sees the picture which needs to be seen by the left eye, and the right eye of the viewer cannot see anything. When the right-eye picture is played, the right eye sees the right picture, and the left eye cannot see the picture, so that the left eye and the right eye respectively see the respective left picture and the respective right picture, and the 3D effect is realized. The process is alternated at least to 120 times per second, and the human eyes can enjoy the 3D pictures which are coherent and not twinkling, so the active 3D display technology requires that the refresh rate of the screen reaches at least 120 Hz.
< Process flow of the present invention >
As shown in fig. 2, the present invention discloses a CAVE system display method using an LED3D screen, which includes the following steps:
and step S1, acquiring the coordinate position of the infrared mark point on the 3D glasses.
The CAVE system uses a multi-camera infrared positioning system to read the position parameters of the two eyes of the user by shooting the infrared mark points attached to the 3D glasses, so as to calculate the position parameters of the two cameras in the virtual environment in the system (the two virtual cameras simulate the positions of the left and right lenses of the 3D glasses).
And step S2, estimating the positions of the two eyes of the user by using the coordinate positions.
The moving capture computer obtains the position parameters of the infrared mark points on the 3D glasses obtained by a plurality of infrared cameras (preferably eight) through a network switch, thereby indirectly obtaining the position parameters of the eyes of the user. The system utilizes MotiveTracker software in a computer, and data are transmitted to the four-channel rendering server and the multi-channel control server through the switch.
And step S3, calculating according to the positions to obtain two groups of pictures displayed relative to the 3D glasses.
The CAVE system then adjusts the images in the display space to match the current position viewed by the user (e.g., a near image to the display screen is enlarged and a far image from the display screen is reduced) according to the change of the positions of the two eyes of the user. And the frame at the corner is calibrated by combining the frame calibration system, so that the display space image cannot be distorted. Wherein the display space image is output for display by four separate three-dimensional rendering services.
And step S4, alternately displaying the two groups of pictures on the LED3D screen.
The multi-channel control server generates picture control signals of four LED3D screens according to the positions of the 3D glasses, and sends the picture control signals of the four LED3D screens to the four-channel rendering servers respectively, so that two groups of calibrated pictures are continuously and alternately displayed on the four LED3D screens.
And step S5, switching the left and right lens switches of the 3D glasses, wherein the switching frequency is matched with the switching frequency of the two groups of pictures which are alternately displayed.
Meanwhile, the 3D glasses cooperate with the continuously and alternately displayed picture images to switch the left and right lenses: when a left eye picture appears, a left eyeglass of the 3D glasses is opened, and a right eyeglass of the 3D glasses is closed; and when the right eye picture appears, the right lens of the 3D glasses is opened, and the left lens of the 3D glasses is closed. In order to synchronize the switching of the left and right eye pictures and the switching of the 3D glasses lenses, an IR emitter is required to be placed above the display space, and a multi-channel control server and the 3D glasses are connected for matching use.
When the left eye picture and the right eye picture are respectively refreshed rapidly at a rate higher than 60Hz, the left eye picture and the right eye picture are overlapped through the brain due to the persistence of vision of human eyes, and stereoscopic impression is generated. The user sees a 3D image that does not flicker after calibration.
The pictures displayed on the LED3D screen are composed of two groups of pictures obtained by shooting existing materials by the left eye and the right eye of two virtual cameras in the virtual environment of the CAVE system.
< specific examples of the present invention >
The LED3D display screen with the point spacing of P1.667 is used, a front screen, a left screen, a right screen and a ground screen are built to form a four-side display space, and a video splicer is an MVC series. In order to respectively render the pictures on the LED screen, four three-dimensional channel rendering servers are also needed, and the servers adopt the Hewlett packard series. In addition, an infrared tracking system is used for spatial positioning of the camera, and the infrared tracking system comprises eight infrared cameras which are distributed at the corners of the display space.
The user fixes the infrared mark points on the 3D glasses. The 3D Glasses are Active Glasses for TV. The moving capture computer obtains the position parameters of the infrared mark points on the 3D glasses through the eight infrared cameras by the network switch, so that the position parameters of the two eyes of the user are indirectly obtained. The system utilizes software motion Tracker in a computer, and data are transmitted to four three-dimensional channel rendering servers and a multi-channel control server through a switch. The multi-channel control server matches the coordinate information of human eyes of audiences to a virtual environment for use to obtain two groups of picture images of left and right eyes, so that the picture of a display space accords with the real visual angle of the human eyes, and the picture of the whole display space is undistorted.
The CAVE system displays two groups of calibrated pictures on an LED3D screen continuously and alternately. Meanwhile, the 3D glasses are matched with the continuous and alternate picture display to switch the left and right lenses. In order to synchronize the switching of the left and right eye pictures on the LED3D screen and the switching of the left and right lenses of the 3D glasses, the IR emitter is required to be placed above the display space, connected with a multi-channel control server and matched with the 3D glasses for use.
Fast refresh when the left eye picture and the right eye picture are each higher than 60 Hz. The user sees a 3D image that does not flicker after calibration.
