Abstract

The invention provides a point cloud motion compensation method and device and a computer readable storage medium. The method comprises the steps: obtaining a first position and a second position, wherein the first position is the position of a laser radar at the current moment, and the second position is the position of the laser radar at the previous moment; acquiring laser point cloud data at the current moment, coordinates of any point in the laser point cloud data and a normal vector at any point; and performing motion compensation on any point in the laser point cloud data by adopting the first position, the second position, the coordinate of any point and the normal vector of any point. Accurate compensation of any point in the laser point cloud data is realized.

Description

technical field [0001] The present application relates to the field of point cloud compensation, in particular, to a point cloud motion compensation method, device, computer-readable storage medium, processor and electronic equipment. Background technique [0002] Lidar is widely used in the field of automatic driving. Through laser scanning, Lidar can quickly establish a three-dimensional model around the vehicle, and provide basic data for high-precision map production, obstacle recognition, and precise vehicle positioning, so as to carry out vehicle driving environment. perception. When the carrying platform of the lidar configuration is in motion, if the position of the lidar changes between two consecutive frames, the position where the laser hits the surface of the object will also change, even if the object has not moved. In the prior art, there is already a method for compensating point cloud displacement caused by lidar motion, but the accuracy of point cloud motio...
