Abstract

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 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 a radio-controlled helicopter and a base station. In this paper, we propose a method to distinguish AR markers and micro QR codes automatically, and show results of discriminated rates in the experiment.
