Self-location Detection Method for Moving Objects Using One Camera and Multiple Light Sources

Recently, robots are widely used for transporting materials, parts and so on at manufacturing sites, It is predicted that they will be introduced to general facilities and homes in near future. For expanding the activity of robots, it is necessary to realize a robot capable of autonomous movement, and it is important to detect the self-position of robots in order to enable independent movement. As a general position detection method, there is a method in which an object or a pattern serving as a landmark is set as a landmark and its own position is detected by performing image processing. However, it takes much time to prepare and process, and it costs too much, so it is difficult to introduce it to general facilities and homes. Therefore, it is desired to realize a position detection method with easier preparation in advance and lower installation cost. In this presentation, we propose a simple method of location detection for a robot using several LED illumination and one camera.
