Abstract

The embodiment of the invention discloses an environment detection system, method, equipment and medium for an unmanned vehicle. The system comprises a first preset number of laser radars, a second preset number of millimeter wave radars and a third preset number of cameras. The laser radars are arranged on at least one of the two sides of the head of a vehicle, the two sides of the tail of the vehicle, the roof of the vehicle and a front bumper and used for detecting first obstacle information in the driving environment. The millimeter wave radars are arranged on at least one of the two sidesof the head of the vehicle, the two sides of the tail of the vehicle and the front bumper and used for detecting second obstacle information in the driving environment; the cameras are arranged at the position of a rearview mirror in the vehicle and used for detecting third obstacle information and / or color texture information in the driving environment. Through the technical scheme of the embodiment of the invention, the system has the capability of integrally sensing the environmental information.

Description

technical field [0001] Embodiments of the present invention relate to unmanned driving technology, and in particular to an environment detection system, method, device and medium for unmanned vehicles. Background technique [0002] With the rapid development of unmanned driving technology, various types of unmanned vehicles are constantly being developed. In order to ensure the safety and reliability of the unmanned driving process, each vehicle needs to have the ability to perceive environmental information as a whole. [0003] At present, existing environmental detection systems are often designed for vehicles with small volume and relatively simple vehicle models, such as unmanned passenger vehicles. [0004] However, in the course of realizing the present invention, the inventor finds that there are at least the following problems in the prior art: [0005] For unmanned heavy-duty tractors used for long-distance logistics transportation, such as heavy-duty trucks, due ...
