Abstract

The application discloses a method and device for obtaining point cloud data. Multiple radars are previously arranged at different locations of a vehicle; the method comprises the following steps: atleast two radars in multiple radars simultaneously scan a target object, and respectively collects one frame of point cloud data, wherein at least two radars are located at different locations of the vehicle; synthesizing the point cloud data collected by at least two radars as one frame of target point cloud data according to a pose relation between the point cloud data collected by at least two radars, wherein the pose relation between the point cloud data collected by at least two radars is determined according to the pose relation among multiple previously determined radars. Through themethod disclosed by the invention, one frame of more comprehensive and rich target point cloud data containing multiple angles and multiple wiring harnesses can be obtained.

Description

technical field [0001] The present application relates to the technical field of vehicle radar, in particular to a method and device for obtaining point cloud data. Background technique [0002] The collection of discrete vector points collected by the radar after each scan is called a frame of point cloud data collected by the radar. According to the point cloud data of the radar, functions such as ranging, target recognition, and labeling can be realized. [0003] In the prior art, usually only one radar is set on the self-driving vehicle for collecting point cloud data. In this way, due to the limited beam and angle of a radar, the comprehensiveness and richness of the obtained point cloud data are relatively low. Contents of the invention [0004] The main purpose of the embodiments of the present application is to provide a method and device for obtaining point cloud data, which can improve the richness and comprehensiveness of the point cloud data. [0005] A meth...
