Problems solved by technology

[0004] Now people generally use GPS positioning technology to realize vehicle positioning, but in areas with low satellite coverage or urban roads covered by tall buildings, there is a large deviation between the real position of the vehicle and the measured position, which cannot meet the needs of precise vehicle positioning
In addition, wireless positioning can also be used, but the disadvantage of wireless positioning is that the wireless signal of communication is easily interfered by other wireless signals, weather, etc., resulting in inaccurate distance measurement

Abstract

The invention discloses a 5G-based high-precision sensing method for road-vehicle coordination. The roadside equipment is used to realize the horizontal and vertical distance measurement of the target vehicle on the road; the GPS positioning information of the vehicle is obtained, and the position of the target vehicle is converted into GPS positioning information output, so as to realize the precise positioning of the vehicle. The technical solution of the invention solves the problem that satellites are easily blocked by tall buildings in urban roads, meets the functional requirements of automatic driving; breaks through the limitation of bicycle perception, and obtains more comprehensive operating environment information.

Description

technical field [0001] The invention belongs to the technical field of intelligent transportation vehicle-road coordination, and in particular relates to a 5G-based high-precision sensing method for road-vehicle coordination. Background technique [0002] The traffic system is a complex system. If only relying on intelligent driving vehicles to solve the traffic congestion problem and reduce the occurrence of traffic accidents, its reliability is not high. The perception system of a vehicle is generally composed of a millimeter-wave radar and a visual sensor. Due to the disadvantages of the visual sensor and errors caused by vehicle movement, it will cause difficulties in target recognition when the target object is blocked or the distance is too low and the pixels are too low; when the vehicle goes up and down When the slope is high, there will be a large deviation in the range measurement and speed measurement of the target by the millimeter wave radar. The roadside senso...
