Filling the holes of 3D body scan line point cloud

摘要：

Our team developed a portable three dimension (3D) body measurement system based on binocular stereo vision. By measuring the body using the system, the body scan line point cloud is reconstructed. Because the surface properties, occlusions and accessibility limitations cause scanners to miss some surface areas, leading to incomplete reconstruction and introducing boles in the resulting models. In this paper, a simple and efficient method is proposed to fill holes. Based on the characteristics of scan line point cloud orderly stored in computer, points that belong to same scan line are fitted into a curve by cubic parametric spline function. Before that, the overlapping points which are not accessible to fit curve are removed and data points that are so dense to make computer poor efficiency are reduced. Because cubic parametric spline has C, C and C continuity at each junction point, the filled points naturally transit to initial points and the holes are disappeared. Then body model without holes whose points are even distributed is constructed.
