摘要： 本文针对服装领域需求所开发的人体扫描系统获取的人体点云数据的特征，提出了人体截面曲线点云的扇形栅格简化方法。该方法运算速度快，且简化率易于调整，能较好的保持点云凹部细节特征，防止轮廓失真。简化后的点云可以直接快速地通过扇形的角度和栅格进行排序，优化了后续点云的光顺去噪及孔洞修补。

Abstract: A portable three dimension (3D) body measurement system was developed. By measuring the body using the system, the body point clouds are reconstructed. Base on the characteristic of point cloud, 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 the following operations of denoising and hole-repairing.
