Embodiment approach

[0120] In a possible implementation manner, the lane determination unit 903 is further configured to:

[0121] judging whether the first feature information of a historical vehicle of the same type as the target vehicle exists in the preset feature information table corresponding to the first area where the corrected body position is located; wherein the preset feature information table There are stored various types of historical vehicles in each second area of ​​each lane, and are used to determine the characteristic information of the vehicle edge position corresponding to the lane where the historical vehicle is located, and the first area includes at least one second area;

[0122] If yes, determine the third lane where the target vehicle is actually located according to the first feature information;

[0123] If the second lane and the third lane are different lanes, the third lane is finally determined as the lane where the target vehicle is actually located.

Abstract

The invention discloses a driving lane judgment method and device and a storage medium, and is used for solving the technical problem of low accuracy of judging a lane where a vehicle is located in the prior art. The method comprises the following steps: loading preset lane information into a target picture, wherein the lane information is determined according to a road scene corresponding to thetarget picture and comprises lane line positions, lane widths and inclination angles of a plurality of lanes in the picture, and the inclination angles are included angles between the lanes and a specified first direction; according to the detected inclination angle corresponding to the first lane where the target vehicle is located, correcting the vehicle body position of the target vehicle to obtain a corrected vehicle body position; and according to the corrected vehicle body position, determining the midpoint of the vehicle body area of the target vehicle, and determining the lane where the midpoint is located as the second lane where the target vehicle is actually located.

Description

technical field [0001] The present invention relates to the technical field of monitoring, in particular to a method, device and storage medium for judging a driving lane. Background technique [0002] As autonomous driving technology becomes more and more widely used, it becomes more and more important to provide accurate navigation for autonomous vehicles. [0003] To provide accurate navigation for self-driving vehicles, it is first necessary to be able to accurately determine which lane the vehicle is driving in. In the prior art, determining the current lane of the vehicle is mainly determined based on information acquired inside and outside the vehicle. For example, the vehicle position information is obtained through GPS devices, direction and distance sensors; lane feature information is detected through image acquisition and recognition technology, and the extracted data is matched with the map database; based on these information, the current lane with the highest...
