ROBOTIC CLEANING DEVICE AND METHOD FOR LANDMARK RECOGNITION
First Claim
1. A method of operating a robotic cleaning device comprising the steps of:
- recording an obstacle detecting device output data of a vicinity of the robotic cleaning device with an object detecting device;
identifying a landmark and its position from the image and deriving information from the landmark to generate a landmark signature;
storing the generated landmark signature;
comparing the generated landmark signature with predetermined landmark signatures; and
determining, whether the generated landmark signature matches one of the predetermined landmark signatures or not;
operating the robotic cleaning device on the basis of the determination.

Abstract
A robotic cleaning device having a main body, a propulsion system configured to move the device across a surface and an obstacle detecting device configured to detect obstacles. The device further includes a processing unit configured to position the robotic cleaning device with respect to the detected obstacles from obstacle detecting device output data, and further to control the propulsion system to move the robotic cleaning device across the surface. The processing unit is configured to identify a landmark and its position from the obstacle detecting device output data, to derive at least one characteristic from the landmark to create and store a generated landmark signature. The processing unit is also configured to compare the generated landmark signature with predetermined landmark signatures and to determine whether the generated landmark signature matches one of the predetermined landmark signatures or not and operate the robotic cleaning device based on the determination.
