Environment perception device and information acquisition method applicable to environment perception device

Abstract

The invention discloses an environment perception device and an information acquisition method applicable to the environment perception device. One embodiment of the environment perception device comprises a camera sensor and a laser radar sensor which are integrated, and a control unit. The control unit is connected with the camera sensor and the laser radar sensor simultaneously. The control unit is used for inputting trigger signals in the camera sensor and the laser radar sensor simultaneously. On the one hand, the camera sensor and the laser radar sensor are designed to be integrated, the problems of poor contact, noise triggering and the like easily caused in the high- vibration high-interference vehicle environment are avoided, the camera sensor and the laser radar sensor are accurately simultaneously triggered, so that high quality data fusion is obtained, and further the environment perception accuracy is improved; on the other hand, the camera sensor and the laser radar sensor are guaranteed to have the consistent overlapped field of vision.

Description

Technical field [0001] This application relates to the field of electronic devices, in particular to the field of perception devices, and in particular to environment perception devices and information acquisition methods applied to environment perception devices. Background technique [0002] In an automatic driving system or an assisted driving system, it is often necessary to collect images and laser point cloud data through cameras and lidar to obtain fusion data, and analyze the fusion data to perceive the driving environment of the vehicle. Therefore, collecting images and laser point cloud data through cameras and lidars to obtain fusion data is the basis for perceiving the driving environment of the vehicle and ensuring the safe driving of the vehicle. At present, the commonly used method to obtain fusion data is: the camera and the lidar are designed separately, which are mounted on the vehicle, and the additional trigger signal is used to input the camera and lidar thro...

Problems solved by technology

[0003] However, when the above-mentioned method is used to obtain fused data, on the one hand, discretely designed cameras and lidars can easily cause problems such as poor contact and noise triggering in a high-vibration and high-interference vehicle environment

On the other hand, due to the difference in shape and viewing angle
