Problems solved by technology

[0003] In related technologies, multiple vehicle-mounted cameras are controlled by one CPU (Central Processing Unit, central processing unit). The driving vehicle regains visual perception input, which makes it impossible for the self-driving vehicle to obtain video data from multiple on-board cameras in real time, which affects the planning decision of the self-driving vehicle and cannot meet the safety requirements of self-driving

Abstract

The invention relates to a method, a device and a system for processing multi-path vehicle-mounted camera control signals. The method comprises the following steps: respectively obtaining a control signal of a first-path processor and a control signal of a second-path processor; selecting a control signal of the first path of processor or a control signal of the second path of processor; and inputting the selected control signal of the first path of processor or the selected control signal of the second path of processor into at least one path of camera in a plurality of paths of vehicle-mounted cameras, so that the first path of processor or the second path of processor controls the at least one path of camera in the plurality of paths of vehicle-mounted cameras. According to the scheme provided by the invention, the video stream data of multiple paths of vehicle-mounted cameras can be acquired in real time, the acquisition delay of the video stream data of the cameras is reduced, and the safety requirement of automatic driving is met.

Description

technical field [0001] The present application relates to the technical field of automatic driving, and in particular, to a method, device and system for processing control signals of multi-channel on-board cameras. Background technique [0002] In the related art, multi-channel cameras are usually used for autonomous driving vehicles to collect the driving state and surrounding environment information of the autonomous driving vehicle, and the video data of the multi-channel cameras is an important source of information for the autonomous driving vehicle. [0003] In the related art, the multi-channel vehicle camera is controlled by one CPU (Central Processing Unit, central processing unit). When the CPU controlling the camera fails, the autonomous vehicle has no visual perception input, and it is necessary to troubleshoot the CPU to enable the automatic driving. The driving vehicle regains the visual perception input, which makes the autonomous vehicle unable to obtain the...
