Proposal of a Method to Detect Position of Moving Object from a Camera Using LEDs and Markers

The authors proposed a new indoor position detection method using a surveillance camera and LED markers for the increasing demand of robots. Robots such as automatic guided vehicles can be expected to be used not only in factories but also in a wide range of fields, so it is necessary to provide position detection system with easy introduction and high accuracy. The proposed method uses a general surveillance camera to capture a moving target with an LED marker. By using the information from camera image and the angles and height of the camera, a high accuracy position detection can be achieved when the height of the target LED maker can be obtained.
