Disclosed are a robot cleaner and a method for controlling the same. The robot cleaner is capable of recognizing a position thereof by extracting one or more feature points having 2D coordinates information with respect to each of a plurality of images, by matching the feature points with each other, and then by creating a matching point having 3D coordinates information. Matching points having 3D coordinates information are created to recognize a position of the robot cleaner, and the recognized position is verified based on a moving distance measured by using a sensor. This may allow a position of the robot cleaner to be precisely recognized, and allow the robot cleaner to perform a cleaning operation or a running operation by interworking the precisely recognized position with a map.

Robot cleaner and controlling method of the same

Disclosed are a robot cleaner and a method for controlling the same. A plurality of images are detected through an image detecting unit such as an upper camera, and two or more feature points are extracted from the plurality of images. Then, a feature point set consisting of the feature points is created, and the feature points included in the feature point set are matched with each other. This may allow the robot cleaner to precisely recognize a position thereof. Furthermore, this may allow the robot cleaner to perform a cleaning operation or a running operation by interworking a precisely recognized position with a map.
