Embodiment 2

[0059] figure 2 A schematic structural diagram of a planning device for a full-coverage path of a cleaning robot provided in an embodiment of the present invention, as shown in figure 2 As shown, the device includes:

[0060] The obtaining module 501 is used to obtain the map of the area to be cleaned, rasterize the map, and set the starting point and end point of the path preset for the rasterized map;

[0061] The weighting module 502 is configured to assign a preset weight to each grid in the map according to a preset weighting strategy, wherein the weighting strategy includes: decrementing or increasing the weight of the grid row by row, grid The weight of the grid decreases or increases column by column, or the weight ring gradient of the grid decreases or increases;

[0062] The path module 503 is configured to use the starting point of the path in the rasterized map as the current point, use the current point as the center point, use the eight-neighborhood traversal...

Abstract

An embodiment of the present invention provides a method and device for planning a full-coverage path of a cleaning robot. The method includes: acquiring a map of the area to be cleaned, rasterizing the map, and presetting the rasterized map. The starting point and the ending point of the path; according to the preset weighting strategy, assign a preset weight to each grid in the map; use the starting point of the path in the rasterized map as the current point, and use the current point as the center point, use the eight-neighborhood traversal algorithm to obtain the next point, use the next point as the current point, and return to execute the step of using the current point as the center point and using the eight-neighborhood traversal algorithm to obtain the next point , until the current point reaches the end point; the path composed of all current points from the start point to the end point is taken as a full coverage path. By applying the embodiments of the present invention, the path planning process can be simplified and the path planning efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of path planning, in particular to a method and device for planning a full-coverage path of a cleaning robot. Background technique [0002] With the development of intelligent hardware and communication technology, more and more unmanned cleaning robots are used in shopping malls, airports, hospitals and other large places. Most of the unmanned cleaning robots on the market are equipped with a full-coverage path generation mode in order to achieve full coverage of the cleaning area and eliminate sanitary dead spots. [0003] The invention with the application number 201810556654.0 provides a path planning method for mobile vehicles, which belongs to the field of navigation, including dividing the operation area of ​​the mobile vehicle into blocks with the grid as the smallest unit to obtain operation blocks. The reciprocating operation is performed in the operation block by traversal; when the mobile carrie...
