This study proposes an information transmission device constructed by a LED panel and a video camera. The LED panel displays various patterns of AR markers, QR and micro QR codes. Then, from images taken by the video camera, some information and 3D position and pose of the camera from the LED panel are extracted. We are planning to apply this system for a communication between moving objects. In this paper, we propose a method to distinguish AR markers, QR and micro QR codes, and show results of discrimination rates and the altitude estimation accuracy in the experiment.
