Title:
SELF-PROPELLED VACUUM CLEANER, SYSTEM, AND OBJECT RECOGNITION METHOD
Document Type and Number:
WIPO Patent Application WO/2020/213294
Kind Code:
A1
Abstract:
This self-propelled vacuum cleaner is provided with: a camera (5) for capturing an image of a space; an object recognition algorithm for recognizing an object from the captured image; and a distance measurement sensor that is directed at the floor in the advancing direction of the self-propelled vacuum cleaner and is for calculating distances. When the object recognition algorithm recognizes an object, the self-propelled vacuum cleaner advances while calculating the average value of the sensor values from the distance measurement sensor, and when the difference between the average value and the latest sensor value exceeds a threshold, the self-propelled vacuum cleaner calculates the presence or absence of an object and the distance to the object. As a result of this configuration, it is possible to provide a self-propelled vacuum cleaner that is capable of avoiding interruption of cleaning due to entanglement of a cable or the like as much as possible.
