Abstract

The invention discloses a point cloud map construction method and device and electronic equipment, and belongs to the technical field of point cloud map construction, and the method comprises the steps: collecting environment point cloud information to generate a first local point cloud map when an unmanned vehicle moves according to a preset route; filtering a preset static target in the first local point cloud map to obtain a second local point cloud map; filtering a dynamic target in the second local point cloud map to obtain a third local point cloud map; and constructing a target point cloud map based on each third local point cloud map generated in the moving process of the unmanned vehicle according to the preset route. Through the point cloud map construction scheme disclosed by the invention, the dynamic target and the static target with relatively low reference value in the point cloud map can be filtered out, the high-quality point cloud map is obtained, and more accurate position information is obtained during subsequent positioning.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of point cloud map construction, and in particular, to a point cloud map construction method, device, and electronic device. Background technique [0002] In the field of unmanned vehicle driving, point cloud maps are usually used to express scene information. A point cloud map usually includes multiple point cloud points with semantic information, as well as the three-dimensional position information of each point cloud point in the world coordinate system; these point cloud points can construct and indicate the specific distribution of different objects in space in a scene. Happening. [0003] In the actual application process, the driverless vehicle establishes a point cloud map based on the previously collected environmental point cloud information, and uses the features of the currently collected point cloud information to match the point cloud map to achieve the purpose of positi...
