CAMERA-BASED INDOOR POSITION RECOGNITION APPARATUS AND METHOD
First Claim
1. A camera-based indoor position recognition apparatus comprising:
- a floor capturing unit capturing a floor image by controlling a camera installed on a ceiling of an indoor space;
a grid map generator constructing a grid map including cell images and position values by dividing the captured floor image into cells of a predetermined size and assigning the position values to the cells;
a transceiver performing a wireless data communication with a robot in the indoor space; and
a controller controlling the floor capturing unit and the grid map generator, and providing an identifier-registration and a current position-information to the robot in accordance with an identifier-registration-requesting message and a position-information-requesting message of the robot, wherein the identifier-registration-requesting message and the position-information-requesting message of the robot are delivered from the transceiver.
