Moreover, since the accuracy of satellite positioning in the prior art is generally at the meter level, vehicle positioning deviations may occur, for example, positioning a vehicle currently driving on a road side road to the main road of the road
In addition, since there are often multiple lanes on roads in the real world, existing positioning methods are used to locate the vehicle on the road on the road map, but cannot determine the lane where the vehicle is located, so it can only provide road-level path planning or path guidance. information
Referring to Figure 1, if the vehicle is driving on road A, the purpose The ground is on road C, because the existing positioning method cannot locate which lane the vehicle is driving on road A, and cannot...

The invention discloses a vehicle positioning method, a navigation method and related devices. The vehicle positioning method comprises the steps that satellite positioning information and driving information of a vehicle are acquired, absolute position information of the vehicle is obtained, and a road where the vehicle is located in a road map is determined according to the absolute position information of the vehicle; according to the road where the vehicle is located, the vehicle line information of each lane of the road in a road map is obtained; the vehicle collects image information ofa road where the vehicle is located, and lane line information of each lane in the image is obtained; and the vehicle line information of each lane in the image is matched with the vehicle line information of each lane of the road in the road map to obtain positioning information of the lane where the vehicle is located in the road map. According to the invention, the vehicle is positioned to thelane of the road by collecting the image information of the road where the vehicle is located and combining the lane-level road map, so that the problem of inaccurate vehicle positioning in the priorart is solved.
Description
technical field [0001] The invention relates to the field of computer vision, in particular to a vehicle positioning method, a navigation method and related devices. Background technique [0002] In the prior art, the positioning of the vehicle through the satellite navigation system can only locate the vehicle on the road. According to the position of the vehicle on the road, path planning or path guidance is carried out. Moreover, since the accuracy of satellite positioning in the prior art is generally at the meter level, vehicle positioning deviations may occur, for example, positioning a vehicle currently driving on a road side road to the main road of the road. In addition, since there are often multiple lanes on roads in the real world, existing positioning methods are used to locate the vehicle on the road on the road map, but cannot determine the lane where the vehicle is located, so it can only provide road-level path planning or path guidance. information. refe...
