Abstract

The invention relates to a method and device for positioning obstacles in semantic maps, computer equipment and a storage medium. The method comprises the steps of: obtaining an obstacle coordinate ofan obstacle and a running speed of the obstacle; and selecting an initial area in a semantic map according to the obstacle coordinate and a preset selection radius, adopting a preset screening rule to screen a plurality of road points in the initial area so as to obtain a target road point matched with the position of the obstacle in the semantic map, and taking the target road point as the position of the obstacle in the semantic map. The screening rule is a rule for screening the road points according to at least one of communication relationships among the running speed of the obstacle, the directions of the road points, the distances between the road points and the obstacle, the distances between the road points and the road points. By adoption of the method, the results of positioning obstacles in semantic maps are more reasonable, correct and reliable.

Description

technical field [0001] The present application relates to the technical field of automatic driving, in particular to a method, device, computer equipment and storage medium for locating obstacles in a semantic map. Background technique [0002] With the rapid development of science and technology, the development of autonomous driving technology is getting faster and faster, and it is constantly being applied in all walks of life. [0003] In the process of automatic driving, vehicles often use preset high-precision maps, such as semantic maps, to know the road conditions and navigate the road conditions. Therefore, obstacles, such as vehicles and pedestrians, need to be located in the semantic map to identify Obstacle location to determine navigation strategy. Therefore, the accurate positioning of obstacles in the semantic map is particularly important. Usually, people use sensors to detect obstacles, such as cameras to take pictures, or combine radar to detect obstacles...
