Photoelectric detection aerial target matching method for point target

The invention relates to a photoelectric detection aerial target matching method for a point target, which comprises the following steps: traversing target codes and space coordinates for a plurality of frames of multi-target images acquired by a distributed imaging system, carrying out multi-target full-path length calculation by integrating the information, searching a shortest path by utilizing a shortest path convex optimization algorithm, and carrying out point target matching. In this way, matching of multiple targets in different detectors is achieved, then the corresponding relation of observation of the same target by the multiple detectors is formed, and then the cross positioning function of the same target is effectively achieved. The method can be applied to distributed photoelectric cooperative detection multi-target cross positioning. Compared with the prior art, the method has the beneficial effects that a target corresponding relation can be quickly formed for a plurality of aerial point targ
