Sparse point cloud multi-target tracking method fusing spatio-temporal information

The invention provides a sparse point cloud multi-target tracking method fusing spatio-temporal information, and belongs to the field of 3D vision. According to the method, the point cloud feature extraction network is used as a trunk, multiple frames of point cloud data are input at the same time, time domain information fusion is carried out on extracted features, and therefore missing detectioncaused by point cloud sparseness is avoided. Benefited from the fusion of time-space information, tracking and detection tasks can be more tightly coupled, and detection frames of three frames beforeand after can be predicted at the same time to obtain a track segment of a current target for three continuous frames. Then a distance intersection ratio score of the current trajectory segment and the trajectory tracking result at the previous moment is calculated, and the currently split trajectory segment and the historical trajectory segment are matched and spliced by using a greedy algorithmto obtain a final trajectory tracking result at each moment. The method has the application potential of coping with multi-target tracking under sparse point clouds, has high robustness for target missing detection and false detection, and can still obtain a stable tracking result in sparse point cloud sequence input.
