Problems solved by technology

[0004] However, the binocular detection distance is relatively short, and pedestrians beyond a certain distance from the automatic driving equipment cannot be recognized: the lidar recognition distance is relatively large, but pedestrian recognition based on point clouds is difficult, and the accuracy rate is difficult to guarantee

Abstract

The embodiment of the invention discloses a method and device for determining information of a target object. One specific embodiment of the method for determining the information of the target objectcomprises the following steps: acquiring an image of an identified rectangular frame of the target object; projecting laser point cloud data points into the image based on the external parameters ofa camera and the external parameters of a laser radar; screening point cloud data points projected into the rectangular frame of the target object in the image; determining a filtering window based onthe rectangular frame of the target object; based on the point cloud information in the filtering window, filtering out interference data points with the distance to the laser radar being greater than a preset threshold from the point cloud data points in the rectangular frame of the target object to obtain point cloud on the target object in the rectangular frame of the target object; and determining information of the target object based on the point cloud on the target object and the target object. According to the embodiment, the two-dimensional information of the target object on the image and the three-dimensional information of the target object on the point cloud can be fused, and the extracted information of the target object is accurate and effective.

Description

technical field [0001] The present application relates to the field of computer technology, specifically to the field of automatic driving technology, and in particular to a method and device for determining information of a target. Background technique [0002] In recent years, autonomous driving technology has received great attention from the automatic control industry. In the automatic driving equipment with automatic driving technology as the technical core, pedestrian detection technology plays an important role, and it is a key technology to protect vehicles and pedestrians during the operation of the whole vehicle. The usual method of pedestrian detection technology is to use image information to detect and identify pedestrians, but the distance of pedestrians needs to be obtained by using binoculars or lidar. The overall information extraction process is complicated and the amount of calculation is large. Accurately detecting pedestrian information is a technical p...
