Title:
PATH NAVIGATION PLANNING METHOD AND APPARATUS, STORAGE MEDIUM, AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/024539
Kind Code:
A1
Abstract:
A path navigation planning method and apparatus, a storage medium, and an electronic device (500), relating to the technical field of path navigation. The path navigation planning method comprises: performing obstacle detection within a first variable neighborhood range on each path point on an initial path, and recording the distance between each path point and an obstacle (S102); segmenting the initial path according to the distance (S103); calculating a path offset to obtain an offset path (S104); and smoothing the offset path to obtain a final path (S105). By performing segmented deviation on an overall path of a sweeping robot, the robot can be more reasonably away from an obstacle during movement, such that the movement flexibility and locomotion efficiency of the sweeping robot are improved, and a duration for the robot to arrive at a target point is shortened; moreover, collisions between the sweeping robot and the obstacle can also be reduced, thereby protecting the body of the robot, improving the measurement precision of a sensor mounted on the robot, reducing an error of the sensor, and making path planning and navigation of the sweeping robot more accurate.
