Association method and device of target detection track, equipment and storage medium

The invention discloses a target detection track association method and device, equipment and a storage medium, relates to the technical field of automatic driving, and can improve the accuracy of association of detection tracks of two different sensors. According to the specific scheme, the method comprises the following steps: acquiring first track coordinates of a plurality of first targets detected by a millimeter wave radar and second track coordinates of a plurality of second targets detected by a visual sensor; converting each first track coordinate and each second track coordinate to a camera coordinate system to obtain a first camera track coordinate and a second camera track coordinate; converting each first track coordinate into a pixel coordinate system to obtain a first pixel track coordinate; determining a target matching cost of the first target and the second target according to each first camera track coordinate, each second camera track coordinate, each first pixel track coordinate and each
