Abstract:
A method for controlling a robot cleaner configured to project light of a predetermined pattern to a floor of an area in front thereof in a specific direction and to acquire an image of the area to which the light is projected, according to the present disclosure, includes: (a) acquiring a front view image of the robot cleaner; (b) detecting the pattern from the image acquired in (a); and (c) discriminating a pattern formed by reflected light from a pattern formed by light directly projected from the robot cleaner, from among patterns indicated in the acquired image, on the basis of geometrical characteristics defined by a projection direction of the light and the direction of an optical axis in which the image is acquired when two or more patterns are detected from the image.

Claim (Index 7):
The method of  claim 2 , further comprising (d) updating the reference position,\n wherein step (d) comprises: (d- 1 ) acquiring an image of an area in front of the robot cleaner; (d- 2 ) detecting a fourth pattern formed by light directly projected to the floor from the robot cleaner from the image acquired in step (d- 1 ); (d- 3 ) comparing a distance between the fourth pattern and the reference position with a predetermined allowable distance; and (d- 4 ) updating the reference position to a position of the fourth pattern based on a comparison result in step (d- 3 ).
