Embodiment Construction

[0063] In order to make the objects, technical solutions and advantages of the present application, the present application will be described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are intended to explain the present application and is not intended to limit the present application.

[0064] The blind zone data processing method provided herein can be applied to figure 1 The application environment shown. Wherein, the server 101 communicates with the radar 102, the image acquisition device 103 over the network. The server 101 can be a stand-alone server or a server cluster consisting of a plurality of servers; radar 102 is any laser radar; image acquisition device 103 is any of a high-definition image acquisition device, for example, a HD camera. It should be noted that when the image acquisition device 103 is mounted to the radar 102, the image acquisition device is mounted to...

Abstract

The invention relates to a blind area data processing method and device, computer equipment and a storage medium. The method comprises the steps of obtaining point cloud data and image data under synchronization time, performing registration on the point cloud data and the image data in an overlapping region between a region covered by the point cloud data and a region covered by the image data, determining a global mapping relationship between the point cloud data and the image data, and according to the global mapping relationship, filling the virtual point cloud data in the detection blind area of the laser radar, and mapping the virtual point cloud data to the image data by using the global mapping relation, so that based on the global mapping relation, the virtual point cloud data of the detection blind area of the laser radar and the pixel points of the detection target in the detection blind area of the laser radar in the image data, determining depth information of the detection target. According to the method, virtual point cloud data of a laser radar detection blind area is obtained based on combined mapping of a laser radar detection area and a camera detection area, and the cost of laser blind area supplementation is reduced.

Description

Technical field [0001] The present application relates to the field of radar technologies, and in particular to a blind zone data processing method, device, computer device, and storage medium. Background technique [0002] With the development of technology, laser radar is widely used in all walks of life, through laser radar to detect the distance, speed, orientation, and posture of the target object, the parameters of the existing positioning tracking technique. Due to the data characteristics and installation of laser radar, there is a part of the blind zone in the detection process, which will cause the deletion of data information. [0003] The prior art provides a plurality of laser radars in the target area, making a radar to cover the blind spot of another radar to achieve the purpose of eliminating the blind zone. [0004] However, the prior art is a method of eliminating a blind spot through a plurality of laser radar to eliminate the blind zone. Inventive content [...
