Abstract

The invention provides a point cloud data screening method and device. The point cloud data screening method comprises the steps of: acquiring to-be-identified point cloud data which is obtained through the scanning a first region by using a radar device disposed on a vehicle; and determining point cloud data corresponding to a static object in the to-be-identified point cloud data according to the attribute information of each map grid, wherein each map grid is obtained by dividing the first region, and the attribute information of each map grid is determined according to the parameter information of the vehicle and positioning data collected by a positioning device deployed on the vehicle in the driving process of the vehicle in the first region, the attribute information of the map gridcomprises state information of the map grid, and the state information comprises a passable state and a non-passable state.

Description

technical field [0001] The present disclosure relates to the field of computer technology, in particular, to a point cloud data screening method and device. Background technique [0002] During the driving process of the self-driving vehicle, the point cloud data collected at the current moment will be matched with the pre-built point cloud map to realize the positioning of the self-driving vehicle. If there are too many point cloud data of dynamic objects in the point cloud map, or too many dynamic objects in the point cloud data collected by the self-driving vehicle, the matching accuracy will be affected when matching the point cloud data of the self-driving vehicle with the point cloud map , which in turn affects the positioning accuracy of the autonomous vehicle. [0003] In related technologies, in order to eliminate the point cloud data of dynamic objects in point cloud data and obtain point cloud data corresponding to static objects only, point cloud data at differe...
