Abstract

The embodiment of the present invention discloses a method, device, device, and storage medium for fusion processing of perception information of intelligent driving roadside equipment. The perception sub-information transmitted by the roadside equipment, the perception sub-information has the same time stamp based on the time calibration between different roadside equipment; the fusion algorithm is used to perform fusion processing on the perception information set. The embodiment of the present invention solves the problem that the sensing range of the vehicle-mounted sensing device is small and the cost of deploying more sensing devices on the vehicle is relatively high during driving, expands the sensing detection range during driving, and reduces the cost of single-vehicle sensing devices. The deployment cost ensures the accuracy of fusion processing results and helps promote the promotion of intelligent transportation technology.
