Cleaning path guidance method combined with dirt detection mechanism
First Claim
1. A cleaning path guidance method combined with a dirt detection mechanism, performed in an automatic cleaning device to generate a cleaning path for the automatic cleaning device to clean an area to be cleaned according to the clean path, wherein a plurality of grids is defined in the area to be cleaned, and the method comprises:
- moving the automatic cleaning device in the area to be cleaned, so as to clear dirt away with the automatic cleaning device;
continuously performing a simultaneous localization and mapping (SLAM) algorithm to determine a current position of the automatic cleaning device, during said moving;
detecting a flow of the dirt cleared away to obtain a dirt level of a current grid, during said moving;
marking the grid as a dirty grid, when the dirt level of the current grid exceeds a threshold;
finding a shortest path passing through all marked dirty grids as a cleaning path according to the marked dirty grids; and
said moving including moving the automatic cleaning device to pass through each marked dirty grid according to the clean path, so as to clean each marked dirty grid sequentially.

Abstract
A cleaning path guidance method combined with a dirt detection mechanism is performed in an automatic cleaning device to generate a cleaning path, so as to guide the automatic cleaning device to clean an area to be cleaned, in which plural grids are defined in the area. The method includes: moving the automatic cleaning device in the area to clear dirt away, and continuously detecting a flow of the dirt cleared away to obtain a dirt level of a current gird; if the dirt level of the current gird exceeds a threshold, marking the grid as a dirty grid; performing an algorithm and finding a shortest path passing through all dirty grids as a cleaning path according to the marked dirty grids; and moving the automatic cleaning device to pass through each dirty grid according to the clean path, so as to clean each dirty gird sequentially.
