Abstract

The invention, which belongs to the technical field of unmanned driving, discloses an exposure control method and device for all-around camera and radar synchronization, a medium and equipment, thereby solving a technical problem that the all-around camera and radar synchronization can not be flexibly configured. To be specific, according to an arrangement mode of all camera modules in the all-around camera and the scanning frequency of the radar, an exposure control signal of each camera module is generated; and then the corresponding camera module is controlled to perform the exposure operation according to the exposure control signals of each camera module. Therefore, the method has advantages of flexible operation, low cost, and high applicability and the like.

Description

technical field [0001] The present invention mainly relates to the technical field of unmanned driving, in particular to an exposure control method, device, medium and equipment for synchronizing a surround-view camera and a radar. Background technique [0002] Obstacle detection in the driving environment of unmanned vehicles is one of the key technologies of the environment perception system of unmanned vehicles. At this stage, the sensors installed on the driverless car are usually used to collect and analyze the two-dimensional images and three-dimensional distance data around the car in real time during driving, and transmit the data to the control system of the driverless car to control the driverless car. Drive the car to take control. Vision cameras and LiDAR are the two most commonly used ranging sensing elements today. The visual camera monitors the objects around the car in real time, and at the same time calculates the distance between the object and the vehicl...
