基于足底扫描仪扫描数据的处理研究

由于环境及设备因素的影响,利用三维激光扫描仪获得的STL格式的足底数据,含有大量冗余数据、噪声点和对模型重构作用不大的点数据。这严重影响了数据读取与显示的效率,不利于后续的曲面重构。针对三维足底扫描系统FS-200 Pro所获得的足底数据,本文提出采用在读取时进行冗余点判断,不重复读取顶点;对读取数据用孤立点去除法和弦高法对扫描线数据进行去噪;通过计算距离与弦高,设定阈值遍历比较每个数据点判断其是否为去除点。经实例检测验证,上述方法能有效去除噪声点,提高简化效率,在保持数据原型的基础上达到了预期效果。

Pelma scanning data processing research based on the plantar scanner

The foot data in STL format acquired from three-dimensional laser scanner contains a lot of redundant data, noise points and little effect reconstruction of point data because of environmental and equipment factors. They seriously affected the efficiency of data access, display and surface reconstruction. In this paper, It propose judge the redundant points when access the data obtained form the 3D foot scanning system FS -200 Pro so that avoid duplication of accessing the vertex data and the method of outl...
