Abstract
A self-driving cleaner includes a main body and a driving unit for driving in a cleaning area. The cleaner suctions foreign material on the floor in the cleaning area. The cleaner includes a first pattern irradiation unit and a second pattern irradiation unit on the front surface of the main body, the first and second pattern irradiation units radiating light in a preset pattern towards the front lower side and the front upper side of the main body, respectively. The cleaner includes a camera on the front surface of the main body, for capturing, at a preset interval, an image including a first light pattern and a second light pattern formed by the first and the second pattern irradiation units, respectively. The cleaner includes a control unit for determining whether a first obstacle exists at a location upwardly spaced apart from the floor, using the image captured by the camera.
