1. A charging apparatus configured to charge a mobile robot, the mobile robot being configured to emit an optical pattern, the charging apparatus comprising:
- a main body configured to perform charging of the mobile robot as the mobile robot docks with the charging apparatus; and
at least two position markers located at the charging apparatus main body and spaced apart from each other, the position markers being configured to create indications distinguishable from a surrounding region when the optical pattern is emitted to surfaces of the position markers.

Abstract
A charging apparatus is configured to charge a mobile robot. The mobile robot is configured to emit an optical pattern. The charging apparatus includes a main body configured to perform charging of the mobile robot as the mobile robot docks with the charging apparatus, and two or more position markers located at the main body and spaced apart from each other. The position markers are configured to create indications distinguishable from a surrounding region when the optical pattern is emitted to surfaces of the position markers.

12. A mobile robot comprising:
-
a pattern emission laser configured to emit an optical pattern including a horizontal line pattern; a pattern image acquisition unit configured to acquire an input image by capturing an image of an area to which the optical pattern is emitted; a pattern extraction unit configured to extract two or more position marker patterns spaced apart from each other from the input image; a position information acquisition unit configured to acquire a distance between the position marker patterns extracted by the pattern extraction unit; and a charging apparatus identification unit configured to identify a charging apparatus by comparing the distance between the position marker patterns with a predetermined reference value. - View Dependent Claims (13, 14)
