Embodiment Construction
[0021] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.
[0022] Such as figure 1 , figure 2 As shown, the present invention is based on a multi-optical path installation error compensation control method based on off-target offset, which specifically includes the following steps:
[0023] Step 1. Turn on the tracking equipment, power on the master control computer, servo system, video equipment, and laser system;
[0024] Step 2. Obtain the position of the optical axis off-target amount of the video sensor, set a static tracking target at a certain distance L from the video device, L>100m, and ensure that the static tracking target is within the field of view of the video device and as close to the center as possible. Turn on the image tracking function of the servo system, the servo system records the static tracking target miss amount A1, E1, and uploads the static tracking target miss amount A...

The invention specifically relates to a method for compensation and control of multi-optical path installation errors based on miss distance offset, belonging to the field of photoelectric tracking. The method comprises the following concrete steps: step 1, turning on power to start equipment; step 2, acquiring the miss distance position of the optical axis of a video sensor; step 3, acquiring the miss distance of indicating light for laser ranging; and step 4, resolving the spatial inclined angle between the optical axis of the video sensor and the optical axis of a laser system, and adding the inclined angle into tracking control of a servosystem as compensation. The method employs a stationary target and laser-ranging visible light for image tracking, resolves the spatial inclined angle between the two optical axes and compensates tracking control with the spatial inclined angle; so the problem that range finding of a to-be-tracked target not located on the optical path of a laser ranger cannot be realized in photoelectric tracking, especially in precise tracking.
Description
technical field [0001] The invention belongs to the field of photoelectric tracking, and in particular relates to a multi-optical path installation error compensation control method based on off-target offset. Background technique [0002] The photoelectric tracking system is a precision observation instrument widely used in land-based, sea-based, and space-based real-time tracking of relative moving targets. It generally consists of an optical system (telescope or camera), a servo system (tracking TV, tracking frame, Tracking processor and electronic control), angle measuring system (azimuth and pitch angle encoder or speed measuring machine), payload (laser range finder, etc.), recording system (camera or measuring TV) and auxiliary system (computer), etc., It integrates optics, electronics, automatic control technology, precision machinery technology and computer technology. [0003] The photoelectric tracking system can be divided into two types: TV tracking and infrare...
