Problems solved by technology
The focus of this invention is to use image processing to detect the center of the target so as to lock the target, but it cannot ensure the accuracy of manual capture of the target, that is, the target must be within the search window of the tracking frame of the manual capture target
On the other hand, if the target and the background with the same gray level as the target are included in the search window of the tracking frame, the center of gravity of the edge of the image processing cannot be aligned with the target
[0005] After searching, no other similar patents and other documents have been found so far

The present invention proposes an unmanned carrier photoelectric system target capture system and method, using GPS or Beidou clock data to mark the exposure time of each frame of video image, so as to obtain the video image exposure time and current frame of the target observed by the operator. Video image exposure time, construct the function of GPS or Beidou clock and photoelectric system movement speed, record the movement trajectory of photoelectric system, calculate the movement angle of photoelectric system aiming line within the exposure time difference of two frames of video images, according to the video of the target observed by the operator The position coordinates in the image, so as to calculate the position of the target in the current frame video image, so that the photoelectric system can accurately and quickly capture the target.
Description
technical field [0001] The invention belongs to the field of photoelectric systems, and mainly relates to a system and method for an automatic tracking system to quickly and accurately capture a target, in particular to a method for an automatic tracking system of an unmanned carrier photoelectric system to capture a target. Background technique [0002] With the continuous development of science and technology, the role of unmanned vehicles, unmanned aerial vehicles, and unmanned ships is becoming more and more obvious. They can not only complete the tasks of conventional carriers, but also complete tasks that manned carriers cannot complete. Or tasks performed under particularly dangerous conditions, which greatly reduces the risk factor of the operator. [0003] At present, the unmanned carrier system is equipped with a high-definition photoelectric system, and the image data is transmitted to the unmanned carrier control center through wireless transmission. Due to the ...
