Abstract :
We present a new method of image coding in structured light 3D scanning called color-coding. The method reduces the number of projected patterns needed to generate the code used to retrieve depths of an object being scanned to only three slides, each one containing RGB values that identify the vertical image stripes correctly. The technique converts the RGB values to the well-known Gray-code algorithm values, making easier and faster the scanning process.
