Abstract

The invention relates to a signal synchronization method and system, and the method comprises the steps: an image signal processing unit carries out the target detection processing of a first simulation image in response to the receiving of the first simulation image of a to-be-tracked target sent by an image simulation injection unit, and generates a first control instruction, the first control instruction is sent to the servo control unit; or, the image signal processing unit responds to the received first real image, sent by the photoelectric imaging unit, of the target to be tracked, performs target detection processing on the first real image, generates a second control instruction and sends the second control instruction to the servo control unit; and the servo control unit responds to the received first control instruction or the second control instruction, and completes the control response of the tracking turntable according to the first control instruction or the second control instruction. Signal synchronization of closed-loop tracking of the photoelectric tracking system in two different modes of real object and image injection simulation is realized, and the system is ensured to work stably in the two modes.

Description

technical field [0001] The invention relates to the field of optoelectronic technology, in particular to a signal synchronization method and system. Background technique [0002] The photoelectric tracking system can capture the target, automatically closed-loop tracking and output tracking target information, and has been widely used in military, security and other fields. The performance of the photoelectric tracking system directly affects the application effect, and only relying on in-field simulation or out-field test methods to test the performance of the photoelectric tracking system has great limitations. [0003] The target to be tracked can be tracked based on the physical object and the image injection simulation, and the image signal processing unit can process the real image of the target to be tracked or the simulation system. However, the working states of the optoelectronic tracking system in the physical and image injection simulation modes may be inconsist...
