| Abstract: | The digitalization process of 3D human body color data captured by the 3D laser scanner is taker as the example to discuss the algorithms commonly used during data pretreatment which includes noise point deletion, aiming at multi-sensor scan data, and merge multi-sensor data, and 3D human body model reconstruction which includes human data reconstruction, triangle meshes decimation, mesh smoothing and mesh subdivision, and features of the algorithms. A processing instance is given and the ideal 3D human body model is obtained. By direct processing of the 2D color images captured by color sensors, the color edge of 3D color data is extracted, and finally, the 3D color digitalization model is constructed. |
