Target acquisition system and method for unmanned carrier photoelectric system

Abstract

The invention provides a target acquisition system and method for an unmanned carrier photoelectric system. Time of exposure moment of each frame of video image is annotated by employing GPS or Beidou clock data; exposure time of video image of a target and exposure time of a current frame of video image observed by an operator are acquired; a function between a GPS or Beidou clock and the movement velocity of the photoelectric system is established; movement tracks of the photoelectric system are recorded; a movement angle of a line of sight in the exposure time difference of two frames of video images is calculated; and the location of the target in the current frame of video image is calculated according to the location coordinate of the target in the video image of the target observed by the user. The photoelectric system is enabled to acquire the target accurately and rapidly.

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 ...

AI Technical Summary

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
