基于三维人体点云的尺寸提取是非接触式人体尺寸测量的重要方法之一。但是由于人体自身遮挡以及扫描死角等问题，扫描人体所得点云往往存在大量孔洞。为此，该文提出了一种面向人体尺寸测量系统的点云孔洞修补方法。该方法首先调整人体点云位置，然后采用映射法分割人体点云取横截面，接着确定横截面轮廓上孔洞位置，最后通过基于最小二乘的二次曲线拟合修补点云数据。实验结果表明，利用该算法拟合得到的人体点云横截面尺寸与直接对模特手工测量得到的尺寸基本一致，对尺寸测量数据的比较得出误差小于3％。

Measurement methods based on the three-dimensional human point cloud are important ways for extracting measurement of body in a non-contract way .However , due to the body's own shelter , scanning dead and other issues , the resultant scanning point cloud often has lots of holes .In this paper , we present a method to repair holes in the point cloud for body measurement system .Firstly, it adjusts the position of the body point cloud, and divides the body point cloud using the mapping method to take a cross-section.It then determines the cross-sectional profile of the holes on the location .Finally through conic fitting based on least squares patch point cloud data , it repairs the holes .Experiments prove that the measurements of the body point cloud model obtained by our method are consistent with the measurement manually acquired , whose difference is within 3%.
