Detailed Description
It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the application.
The embodiment of the application provides an automatic focusing star searching method based on a telescope. The execution main body of the telescope-based auto-focusing star searching method comprises at least one of a server, a terminal and the like which can be configured to execute the method provided by the embodiment of the application. In other words, the telescope-based auto-focusing search method may be performed by software or hardware installed in a terminal device or a server device. The service end includes but is not limited to: a single server, a server cluster, a cloud server or a cloud server cluster, and the like.
Example 1: referring to fig. 1, a flow chart of a telescope-based auto-focusing star searching method according to an embodiment of the invention is shown. In this embodiment, the telescope-based auto-focusing star searching method includes:
s1, acquiring an initial starry sky image, and selecting a reference star with the highest brightness value from the initial starry sky image.
In the embodiment of the invention, the initial starry sky image refers to an image obtained by observing starry sky by using an astronomical telescope. The size of the stars in the initial starry sky image is similar to that observed by naked eyes. The reference star can be used as a star for determining the observation angle of the telescope, and the higher the general brightness value is, the easier the star name is determined.
S2, adjusting a preset lens observation angle according to the position relation between the reference star and the central point of the initial starry sky image to obtain a reference observation angle.
The center point of the initial starry sky image is typically the center point of the field of view of the telescope lens. The reference observation angle refers to an observation angle before an observation lens is adjusted to a star to be observed, and the size of the angle to be adjusted is determined according to the reference observation angle and the position of the star to be observed. The lens observation angle refers to an angle when the initial starry sky image is observed.
In the embodiment of the present invention, the adjusting the preset lens observation angle according to the positional relationship between the reference star and the center point of the initial star image to obtain the reference observation angle includes:
connecting the reference star with the center point of the initial starry sky image to obtain an angle adjusting line segment;
moving a pre-constructed lens center point on the angle adjusting line segment, and judging whether the lens center point coincides with the center point of the initial starry sky image;
if the lens center point is not coincident with the center point of the initial starry sky image, returning to the step of moving the pre-constructed lens center point on the angle adjusting line segment;
and if the lens center point is coincident with the center point of the initial starry sky image, stopping moving the lens center point to obtain the reference observation angle.
It can be explained that, for accurate adjustment of the angle of the telescope lens, the reference star is required to be used as a reference point for adjusting the lens, and when the reference star is adjusted to the center of the telescope field of view, the adjustment is completed. At this time, since the names of the reference stars are known, the reference viewing angle can be determined by combining the geographical position and the viewing time at this time.
S3, acquiring a reference star sky image observed under the reference observation angle, and taking the reference star body as a circle center to locate a dynamic circle.
It can be understood that the positioning dynamic circle refers to a dynamic circle with a constant center position (namely a reference star position) and a uniform-radius amplification.
In the embodiment of the present invention, the locating dynamic circle using the reference star as a center of a circle includes:
acquiring a central point of the reference star field image;
judging whether the center point of the reference star image coincides with the reference star;
if the center point of the reference star image is not coincident with the reference star, finely adjusting the lens observation angle until the center point of the reference star image is coincident with the reference star;
and if the center point of the reference star image coincides with the reference star, taking the center point of the reference star image as a circle center to make a circle with the radius increased according to a preset rate, so as to obtain the positioning dynamic circle.
It can be explained that, because after the adjustment of the angle adjustment line segment, there is a possibility that the center points of the reference star and the reference star image have a slight gap, fine adjustment can be performed to ensure that the center point of the reference star image coincides with the reference star. The predetermined rate of increase of the dynamic radius of the positioning may be 1mm per second.
S4, judging whether a star in the positioning dynamic circle forms a triangle or not, and including the reference star. It can be explained that, since the positional relationship between each star and the surrounding star is unique, the names and attributes of the reference star can be obtained by knowing the positional relationship between the surrounding shape and the reference star. The number of the surrounding stars can be 3, and when the triangle formed by the surrounding 3 stars can enclose the reference stars, the names of the reference stars can be obtained according to the interrelation of the positions of the stars.
In the embodiment of the present invention, the determining whether a star in the positioning dynamic circle forms a triangle and includes the reference star includes:

if the star is positioned at the round edge of the positioning dynamic circle in the amplification process of the positioning dynamic circle, taking the star on the round edge as a triangular point to be stopped;
Judging whether two stars exist in the positioning dynamic circle and the triangle which is formed by the triangle point to be stopped and can contain the reference stars or not;
if the triangle which can contain the reference star is not formed by the two stars and the triangle point to be stopped in the positioning dynamic circle, returning to the step of judging whether the triangle which can contain the reference star is formed by the two stars and the triangle point to be stopped in the positioning dynamic circle;
if the triangle which can contain the reference star is formed by the two stars and the triangle point to be stopped in the dynamic positioning circle, judging that the triangle formed by the stars is formed in the dynamic positioning circle and the reference star is contained in the dynamic positioning circle.
It should be understood that, in the process of amplifying the positioning dynamic circle, determining whether two stars exist in the positioning dynamic circle and the triangle formed by the triangle to be terminated and including the reference star may be expressed as determining whether the intersecting star encloses the reference star with any two stars in the circle when the circular edge of the positioning dynamic circle intersects the star each time.
And if the triangle formed by the stars does not exist in the positioning dynamic circle and the reference stars are included, returning to the step of acquiring the reference star sky image observed under the reference observation angle.
And if the star forms a triangle in the positioning dynamic circle and the reference star is included in the triangle, executing S5 to determine the radius of the positioning dynamic circle so as to obtain a positioning static circle.

calculating the radius of the positioning static circle and the length of each side length of the triangle;
inquiring star attributes of the reference star in the star database according to the shape attributes of the triangle, the triangle area, the radius of the positioning static circle and the length of each side length of the triangle.
It is understood that the shape attribute refers to whether the triangle is an obtuse triangle, an acute triangle, or a right triangle. In the embodiment of the present invention, before querying a star attribute of the reference star in a pre-constructed star database according to the relative positional relationship between the reference star in the positioning static circle and three stars forming a triangle, the method further includes:
acquiring star data, wherein the star data comprises the shape attribute, the triangular area, the length of each side length of a triangle and the radius of a positioning static circle of a triangle surrounding a reference star when each star with known attribute in the star space is used as the reference star;
classifying stars in the star space once according to the shape attribute of the triangle surrounding the reference stars to obtain a triangle shape attribute catalog;
Secondarily classifying stars in the triangular attribute catalog according to the radius of the positioning static circle to obtain a positioning circle radius catalog;
classifying the stars in the positioning circle radius catalog for three times according to the triangular area to obtain a triangular area catalog;
and classifying the stars in the triangular area catalog four times according to the length of each side length of the triangle to obtain the star database.
It should be appreciated that the satellites may be classified according to the shape attribute, triangle area, length of each side of the triangle, and radius of the positioning static circle of the triangle surrounding the reference satellite, so as to facilitate retrieval. For example: when the triangles are obtuse angles, the triangles are classified into the class, the triangles in the obtuse angles are classified again according to the radius of the positioning static circle, and the radius classification standard of the positioning static circle can be [1mm-2 mm), [2mm-3 mm), and the like. The classification standard of the triangular area can be、/>Etc.
In the embodiment of the present invention, the classifying the stars in the triangle area directory four times according to the lengths of the sides of the triangle to obtain the star database includes:
Sequencing the side lengths of the triangles according to the length-size relationship to obtain a side length sequence;
and classifying the stars in the triangular area catalog four times according to the side length sequence to obtain the star database.
Alternatively, the classification may be based on a length sequence, for example: 1mm, 3mm, 3.5mm are classified as such, and 3mm, 4mm, 5mm are classified as such.
