Document Type and Number:
WIPO Patent Application WO/2019/109228
Kind Code:
A1
Abstract:
The present invention relates to a visual relocation-based method and apparatus for a sweeper to continue sweeping after power-off, and a sweeper. The method comprises: when a sweeper is powered off, storing into a scene map a scene image acquired in a sweeping process of the sweeper and a scene image of the position where the sweeper is powered off; after power-on, acquiring a current scene image, selecting from the scene map a scene image having the highest matching degree with the current scene image, and calculating the relative position between the sweeper and a position corresponding to the scene image having the highest matching degree; and calculating a movement path according to the relative position, and driving the sweeper to move to the position corresponding to the scene image having the highest matching degree according to the movement path and sweep according to a preset policy. According to embodiments of the present invention, after being restarted, the sweeper can be driven to move to a position corresponding to a scene image, in the scene map, having the highest matching degree with the current scene image and continue sweeping according to a preset policy; thus, a function of continuing sweeping after power-off is implemented, thereby avoiding re-sweeping an area which has been swept and improving the sweeping efficiency.
