Laser point cloud data recognition method and device

Abstract

Embodiments of the present invention provide a laser point cloud data recognition method and device, the method comprising: acquiring target laser point cloud data, the target laser point cloud data is based on the laser points in the three-dimensional laser point cloud data in the target three-dimensional scene The following coordinate information is obtained; the target laser point cloud data is input into the trained point cloud deep learning model to obtain the target object recognition result, and the trained point cloud deep learning model is based on the labeling information of the sample target object The obtained model, the annotation information includes the size and position of the sample target object, the annotation information is the information obtained according to the prediction data output by the point cloud depth model, and the prediction data includes the predicted size and position of the sample target object Location. The laser point cloud data recognition method and device provided by the embodiments of the present invention can improve the labeling efficiency, and further improve the recognition efficiency of the target object.

Description

technical field [0001] Embodiments of the present invention relate to the field of computers, and in particular to a laser point cloud data recognition method and device. Background technique [0002] With the development of autonomous driving technology, it is particularly important to identify target objects around the vehicle (such as vehicles, pedestrians, tricycles, bicycles, etc.). ) to detect target objects around the vehicle, the laser radar emits a laser beam around, and when the laser beam encounters an object, it returns the laser point cloud, and identifies the surrounding target objects and the size, position, movement, and speed of the target object through the laser point cloud Wait. [0003] At present, the main way to identify the target object through the laser point cloud is: manually mark the received laser point cloud point by point in advance to obtain the laser point cloud sample data corresponding to the target object; use the sample data for machine...
