Method, device and system for testing accuracy of target classification algorithm and medium

The embodiment of the invention discloses a method, device and system for testing the accuracy of a target classification algorithm and a medium. The method is executed by a server and comprises the following steps: acquiring an algorithm relative position between a first vehicle and a second vehicle, first vehicle motion behavior data and second vehicle motion behavior data; the algorithm relative position is determined based on a target classification algorithm according to the first vehicle motion behavior data and the second vehicle motion behavior data; determining a standard relative position between the first vehicle and the second vehicle according to the first vehicle motion behavior data and the second vehicle motion behavior data based on a high-precision map; and determining the accuracy of the target classification algorithm according to the standard relative position and the algorithm relative position. According to the embodiment of the invention, the standard relative position of the high-prec
