摘要：This paper proposes a color encoding structural light approach for the three-dimensional measurement of turbine blade surface. It adopts RGB color mode design coding scheme, by using the six basic colors, red, green, blue, yellow, magenta, and cyan for color-coded stripes. Every three stripes are grouped together, while the color combinations for each group are different. The coding pattern based on these color stripes is projected to the blade. A CCD camera then captures the image modulated by the blade. We then decode this image to obtain the three-dimensional coordinates of the measured points on blade surface. According to the structure light measurement principle, we designed and determined the parameters of the three-dimensional measurement. This paper established a mathematical model of a turbine blade through simulation by using 3ds max software. We designed a three- dimensional measurement system for the simulation, and obtained the three-dimensional coordinates of the blade surface by measuring the turbine blade. Finally, the three- dimensional blade model reconstructed by the measured data is established
