Title:
WALL SURFACE SANDING PATH PLANNING METHOD AND APPARATUS, AND DEVICE AND MEDIUM
Document Type and Number:
WIPO Patent Application WO/2021/212788
Kind Code:
A1
Abstract:
Disclosed are a wall surface sanding path planning method and apparatus, and a device and a medium. The method comprises: acquiring protruding points (1-N) of a wall surface to be sanded, and dividing said wall surface into at least two areas (S110); determining candidate protruding points in an area next to the area where the current protruding point is located (S120); if the area where the current protruding point is located comprises a protruding point that is not traversed, comparing a first distance with a second distance, wherein the first distance is the distance between the protruding point that is not traversed and the current protruding point, and the second distance is the distance between the candidate protruding point and the current protruding point (S130); determining a protruding point which corresponds to the shortest distance from among the first distance and the second distance as the next operation point of the current protruding point (S140); and determining a wall surface sanding path on the basis of the current protruding point and the next operation point of the current protruding point (S150). The method solves the problem of a sanding path of a current sanding device covering a sanding area which does not require sanding, and achieves the effects of optimizing an operation path of the sanding device, improving the sanding efficiency and reducing sanding costs.
