Paper Abstract

As computer graphics technology becomes more popular, a large amount of 3-D model data is required for various purposes. Three-dimensional (3-D) digital modeling of object through 3-D optical scanners has been demonstrated in recent years. However, most current 3-D scanners are usually large, heavy, expensive, and commonly accurate (Mean Square Error is around 0.3mm). Presently, highly accurate, easy-to-use and cheap 3-D shape acquisition system provides viable solutions to meet the requirements of users. In this paper, we introduce a linear structured scanning system covers an area of 600mm by 400mm in width in a high accurate way (MSE is lower than 0.1mm). Hardware setup of the linear structured scanning system and the process of the shape acquisition for 3-D object modeling based on the linear structured scanning system are proposed in this paper. We also proposed a highly accurate calibration method which can overcome complicated calculations of camera parameters. This highly accurate calibration method can be widely applied to linear structured light measurement system. Then we describe the modeling approach of our linear structured scanning system. Finally, reconstruction and visualization results are illustrated and further analyses are discussed in this paper.
