Paper Abstract

A novel system based on color-encoded structured light for 3D shape measurement is presented in this paper; only one image is needed to be captured by the camera, so it has some advantages such as high resolution, rapid measurement. The relationship between color and height is established through color coding, the height of object can be calculated by decoding. According to the measurement principle, the calibration technique of the system is designed. The color stripe encoded pattern with 6 colors, they are three primary colors: red, green, blue and their contrary colors: yellow, magenta and cyan. There are two important characters that the combination of three color stripe order is unique and any two of adjoining color stripes are different. An effective stripe thinning method is put forward. Finally, experiment system is set up, and experiments of measurement cuboids are performed.
