Flight path fusion method and system based on multiple sensors at single intersection

The invention discloses a track fusion method and system based on a single intersection and multiple sensors, and relates to the field of intersection intelligent vehicle management, and the method comprises the steps: firstly determining successfully matched target points and unsuccessfully matched target points in a current frame according to a preset data association algorithm and the radar distance information and camera distance information of each target point of the current frame; then different track information generation strategies are adopted for target points under different conditions, Kalman filtering does not need to be carried out, and therefore the method is high in universality and suitable for distributed sensor track management of various video tracking algorithms and radar tracking algorithms, meanwhile, the corresponding track information generation strategies are selected according to the types of the target points, and the track information generation strategy generation efficiency is improved. The calculation amount and errors in the data fusion process can be reduced.
