Three-dimensional group target trajectory matching method and device

The invention discloses a three-dimensional group target track matching method, and belongs to the technical field of computer vision, and the method comprises the steps: collecting a basic matrix between a view I track and a view II track corresponding to a group target in the same scene from two visual angles; calculating epipolar distance cost vectors corresponding to the first view track and the second view track according to the basic matrix to construct a cost vector matrix, further finding out a plurality of pairs of successfully matched two-dimensional tracks from the first view track and the second view track, and finally obtaining a segmented track set; and re-associating the segmented trajectory set to realize more accurate trajectory matching of the three-dimensional group target. According to the method, on the basis of the two-dimensional tracking trajectory, multiple pairs of successfully matched two-dimensional trajectories are found out from the first view trajectory and the second view traje
