Abstract :
We propose an automated photogrammetric system using visible light communication. Our system can be applied to the measurement of a variety of distances using a light as a reference point. In addition, the matching of same lights in different viewpoints can be automatically done by using unique blinking patterns. A light area is extracted based on a rule of the lighting patterns without a pre-known threshold. Experimental results show that our system can provide enough accuracy for photogrammetry.
