Abstract

The invention discloses a multi-sensor fusion vehicle-road collaborative sensing method for automatic driving. The method comprises a data enhancement module, a point cloud sensing module, an image sensing module, a multi-sensor fusion module, a V2X real-time communication module, a selective compensation module and a positioning module based on SLAM and GPS / INS fusion. Firstly, a public data set is processed through a data enhancement module; the three-dimensional information obtained in the point cloud sensing module and the two-dimensional information obtained in the image sensing module are fused through a multi-sensor fusion module; the position information of the vehicle is obtained by means of a positioning module based on SLAM and GPS / INS fusion, and the automatic driving vehicle is helped to make accurate judgment in a complex environment; meanwhile, perception information is shared through the V2X real-time communication module and vehicles or roads in the surrounding environment, shielding missing information is effectively compensated through the selective compensation module, and the real-time communication efficiency is improved; the method is high in accuracy and reliability, and can effectively solve the problems of information loss and shielding under a complex road.

Description

technical field [0001] The invention relates to the technical field of artificial intelligence, in particular to a vehicle-road collaborative perception method based on point cloud and image multimodal fusion. Background technique [0002] With the continuous development of deep learning theory in recent years, many research fields and industries have set off a revolution in artificial intelligence. Among them, autonomous driving technology is deeply influenced by the development of deep learning and computer vision, and its theory has become increasingly mature and is moving towards industrialization. The core of the autonomous driving system can be summarized as three parts: perception, planning, and control, so it is actually a layered structure, and the perception, planning, and control modules play different roles and influence each other. In the entire automatic driving system, the perception part is the forerunner of the entire system, equivalent to the eyes of the a...
