“A Photogrammetric System Based on Visible Light Communications Using Light Markers”

We propose a photogrammetric system based on visible light communications using a light marker as a reference mark. Our system automatically matches the light markers captured from multiple viewpoints. Each light blinks as a signal based on visible light communications. Using the signal, the automatic matching of the light markers is achieved. In addition, the automatic detection of the light markers is achieved by the rule of pulse position modulation and cyclic redundancy check. In our experimental results, the accuracy of the detection of the light areas and photogrammetry using light markers are discussed.
