[0103] Based on the first embodiment, the second embodiment of the route navigation method of the present invention is proposed, referring to Figure 4 , in this embodiment, step S300 includes:

[0104] Step S310, determining whether there is an obstacle in the target planning path based on the first image and the obstacle avoidance layer;

[0105] Step S320, if not, control the vehicle to travel based on the positioning information and the planned target route.

[0106] In this embodiment, when the first image is obtained, the obstacle avoidance layer corresponding to the current driving scene is obtained, based on the first image and the obstacle avoidance layer, it is determined whether there is an obstacle in the target planning path, if there is no obstacle, Based on the positioning information and the target planned route, the vehicle is controlled to drive, that is, the vehicle is controlled to continue to drive according to the target planned route, so as to improve t...

Abstract

The invention discloses a path navigation method. The path navigation method comprises the following steps of acquiring a target planning path of a vehicle, and determining positioning information ofthe vehicle according to a radar pattern layer corresponding to the vehicle and laser radar; acquiring a first image corresponding to the vehicle by a depth camera; controlling the vehicle to drive according to the positioning information, the first image, an obstacle-prevention pattern layer and the target planning path of the vehicle. The invention also discloses a path navigation device and a computer readable storage medium. The vehicle is positioned by the radar pattern layer, path planning and obstacle prevention are performed according to the positioning information and the obstacle-prevention pattern layer, the positioning accuracy of the vehicle is not affected by the laser radar of which installation height is larger than the height of an obstacle when the obstacle exists in thetarget planning path, and the navigation accuracy and efficiency of the vehicle is further improved.

Description

technical field [0001] The present invention relates to the field of intelligent driving, in particular to a route navigation method, device and computer-readable storage medium. Background technique [0002] SLAM (simultaneous localization and mapping, real-time positioning and map construction) based on the natural environment includes two major functions: positioning and mapping. Among them, the main function of map building is to understand the surrounding environment and establish the corresponding relationship between the surrounding environment and space; the main function of positioning is to judge the position of the car body in the map according to the built map, so as to obtain information in the environment. Secondly, lidar is an active detection sensor that does not depend on external lighting conditions and has high-precision ranging information. Therefore, the SLAM method based on lidar is still the most widely used method in the robot SLAM method, and the SL...
