Abstract

The present application relates to a method, a device, a computer device and a storage medium for locating obstacles in a semantic map. The method includes: obtaining the obstacle coordinates of the obstacle and the driving speed of the obstacle; selecting an initial area in the semantic map according to a preset selection radius according to the obstacle coordinates, and using a preset screening rule to select multiple The road points are screened to obtain the target road point that matches the position of the obstacle in the semantic map, and the target road point is used as the position of the obstacle in the semantic map. Wherein, the screening rule is to filter the road points according to at least one of the driving speed of the obstacle, the direction of the road point, the distance between the road point and the obstacle coordinates, the distance between the road points and the connection relationship between the road points rule. Using this method can make the result of obstacle location in the semantic map more reasonable, accurate 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 The location of obstacles to determine the 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 dete...
