Rail transit external environment perception system and method and rail transit equipment

Abstract

The invention provides a rail transit external environment perception system and method and rail transit equipment. The system comprises an image acquisition device, an environment data acquisition device and a train control device, wherein the image acquisition device is used for acquiring an environment image of an environment; the environment data acquisition device is used for acquiring 3D point cloud data of the environment; and the train control device is used for carrying out 3D space modeling according to the environment image and the 3D point cloud data to generate a running environment model of the train, generating a decision instruction according to the running environment model and controlling the train control unit to execute the decision instruction. Therefore, 3D space modeling is performed according to the environment image and the 3D point cloud data so as to generate the operation environment model of the train, real-time perception of the external environment of therail transit can be realized, the operation efficiency of the rail transit can be enhanced, and the decision instruction can be generated according to the operation environment model so as to ensurethe safety of the rail transit.

Description

technical field [0001] The invention relates to the technical field of traffic equipment, in particular to a rail transit external perception system, a rail traffic external perception method and rail traffic equipment. Background technique [0002] At present, rail transit equipment such as subways and light rails of related technologies usually detect the external environment information of rail transit manually or by special engineering vehicles. [0003] However, the problem of related technologies is that the manual detection method takes a long time and is prone to human error, which is not conducive to the safe operation of rail transit. Although the special engineering vehicle takes less time and has higher precision than the manual method, it is Special-purpose engineering vehicles need to invest a lot of financial and material resources, and occupy a certain amount of space, and whether it is manual or special-purpose engineering vehicles, there is a problem of wea...
