Study of body point cloud simplification based on non-contact measurement

Based on the characteristic of body point cloud data obtained by body scanning system which is developed to satisfy the needs of the garment industry,the paper proposed a method of fan-shaped grids to simplify the body point cloud.The method can be operated with high speed and the simplifying rate can be controlled easily.By this method,the simplified point cloud retained the details in the concave to prevent the contour from distorting.The simplified point cloud can be sorted quickly by fan-shaped angles and grids.The result optimized subsequent operations such as noise elimination and hole-repairing.
