Abstract

A mapping method that includes obtaining a multi-frame image of a parking scene by a camera every other first time interval, obtaining point cloud data of the parking scene by a laser radar every other second time interval, identifying wheel stop information in the multi-frame image by a pre-trained wheel stop identification model, obtaining a wheel stop classification result by fusing the wheel stop information in the multi-frame image, building an initial wheel stop three-dimensional map based on a vehicle positioning result and the wheel stop classification result, and obtaining a wheel stop three-dimensional map by revising the initial wheel stop three-dimensional map in combination with wheel stop position information in the point cloud data.
