Problems solved by technology

[0009] The technical problem solved by the present invention is: in the presence of various errors, when the target cannot be guided into the field of view, use the external guidance data to close the loop, and at the same time make full use of the operator to modify the closed loop to reduce the capture of the target Time - to speed up the process of target acquisition

Embodiment Construction

[0029] The following are specific implementation methods of the present invention. But following embodiment only limits to explain the present invention, and protection scope of the present invention should comprise the whole content of claim, and promptly can realize the whole content of claim of the present invention to those skilled in the art through following embodiment.

[0030] The process of photoelectric tracking and measurement equipment guiding the target is mainly to convert the target position data into the data in the coordinate system of the photoelectric equipment, which is the azimuth and pitch values ​​(A t ,E t ), where t represents time.

[0031] When the external guidance data is selected for closed-loop capture of the target, the closed-loop data (A, E) selected by the servo is:

[0032] A=A t (1)

[0033] E=E t (2)

[0034] When the target cannot be captured, the scan function needs to be started. The start-up process is to set the closed-loop da...

Abstract

The invention discloses a target capturing method based on a dynamic scanning mode, and relates to the development of photoelectric equipment, especially the field of photoelectric equipment under a moving platform. For the photoelectric tracking and measurement equipment, especially the photoelectric tracking equipment under the operating platform, due to the small field of view of the photoelectric detector, and the existence of various errors such as system errors and positioning errors, it is difficult to capture the target. Use the process of evaluating the error characteristics of target capture, formulating different strategies, and designing operation mode loading strategies. Under the premise that the external guidance data cannot capture the target and the operator is not required to manually capture the target, the control strategy and method of the external guidance data, dynamic scanning function and manual intervention are fully utilized to increase the probability of target capture.

Description

technical field [0001] The invention belongs to the field of photoelectric tracking and measurement, and relates to the system design and realization of target capturing of photoelectric tracking and measuring equipment, in particular to a target capturing method based on a dynamic scanning mode. Background technique [0002] Photodetectors are the core components of photoelectric tracking and measurement equipment. Limited by optical design and related indicators, their field of view is generally smaller than other types of detectors under the same working distance conditions. Therefore, in the real-time work of photoelectric equipment, other information needs to be used to capture the target-this process is called external guidance. When guiding the target into the field of view of the detector, due to the existence of various errors, sometimes although the device is always dynamically pointing to the area where the target is located, the target cannot enter the field of v...
