Embodiment 1

[0024] like Figure 1-4 As shown in the figure, an over-the-horizon perception system based on the fusion of vehicle, road and UAV information mainly includes: vehicle-side perception subsystem, road-side perception subsystem, UAV perception subsystem communication subsystem and collaborative perception subsystem system, where:

[0025] The vehicle-side perception subsystem is used to obtain the structural feature information of the surrounding environment of the vehicle and transmit it to the collaborative perception subsystem through Ethernet, including the vehicle-side sensing module and the vehicle-side data processing module;

[0026] The roadside perception subsystem is used to obtain the structured feature information of the roadside surrounding environment and transmit it to the collaborative perception subsystem through the communication subsystem, including the roadside sensing module, the roadside data processing module, and the UAV charging module;

[0027] The UA...

Abstract

The invention relates to a beyond-visual-range sensing system based on information fusion of a vehicle, a road and an unmanned aerial vehicle. A vehicle end sensing subsystem is used for acquiring structured feature information of the surrounding environment of the vehicle; the road end sensing subsystem is used for acquiring road end surrounding environment structured feature information; the unmanned aerial vehicle subsystem flies for a long time and a short distance in the two road end subsystems on the premise of ensuring safety and is mainly used for acquiring structural feature information of surrounding environments of two road end blind areas; the communication subsystem comprises a road end communication module, a vehicle end communication module and an unmanned aerial vehicle communication module which are connected in a wireless communication mode; and the collaborative perception subsystem fuses the vehicle surrounding environment structured feature information and the road end and unmanned aerial vehicle surrounding environment structured feature information after coordinate conversion by using a particle filter algorithm to obtain beyond-visual-range fusion perception. Compared with the prior art, the automatic driving decision planning capability of the vehicle end is enhanced.

Description

technical field [0001] The invention relates to an over-the-horizon perception system based on vehicle, road and unmanned aerial vehicle information fusion, and belongs to the field of intelligent networked vehicle perception. Background technique [0002] An important development direction of automobile intelligence is autonomous driving. In recent years, the technology of autonomous driving vehicles has developed rapidly, and autonomous driving vehicles with different levels of automation have been launched. The operation process of autonomous driving can be divided into five parts: perception, cognition, decision-making, control, and execution. Its key technologies are driving environment perception, vehicle networking and artificial intelligence. In autonomous vehicles, sensors such as positioning, vision, and radar are collaboratively fused, and environmental data collected from images and laser point clouds can be extracted, processed, and fused through algorithms to f...
