Abstract: Laser scanning 3 D modeling was an important way to build a 3 D digital model.Considering the present high-performance portable Creaform3 D scannin g system,in this paper,the product features and the working principles were introduced comprehensively.Combining with the scanning point cloud data of specific object, the process of 3 D model construction was discussed based on Creaform3 D scanning system,and experimental analysis on the effects of the constructed 3 D model wa s carried out.The experimental results showed that Creaform3 D scanning system had following characteristics such as high scanning accuracy,strong integrity,high efi ciency and small constraint.
