ROBOT CLEANER AND CONTROLLING METHOD OF THE SAME

摘要

PURPOSE: A robot cleaner and a control method thereof are provided to precisely recognize the position of the robot cleaner by extracting two or more feature points from multiple images and comparing the information of the feature points with each other. CONSTITUTION: A robot cleaner comprises an image detection unit, a feature point extraction unit, and a feature point matching unit, and a control unit. The image detection unit photographs surroundings and detects the photographed images. The feature point extraction unit extracts multiple feature points from the images and produces feature point sets. The feature point matching unit compares the feature points with each other and matches the feature points. The control unit recognizes the position of the robot cleaner based on the matched results.
