Data Collection and Extraction of Similar Material Model Based on XJTUOM and Geomagic Studio

针对传统的物理测量或机械测量方法测量相似材料模型时易使模型变形且采集数据点有限、操作复杂、效率低等问题,介绍了一种采集并提取相似材料模型点云数据的方法。该方法采用XJTUOM三维白光面扫描系统采集相似材料模型的点云数据,并利用该系统的点云预处理软件对采集到的点云数据进行拼接和对齐处理,然后采用Geomagic Studio点云处理软件对预处理后的点云数据进行数据提取操作。试验结果表明,该方法获取数据量大,测量效率高,点云数据采集和处理精度高,抗干扰能力强。

In order to solve problems of deformed model,limited collected data,complex operation,low efficiency and so on existed in measuring similar material model by use of traditional physical or mechanical measuring methods,the paper introduced a method of collecting and extracting point-cloud data of similar material model.The method adopts XJTUOM 3D white-light surface scanning system to collect point-cloud data of similar material model and point-cloud pre-processing software of the system to put the collected point-cloud data together and in order,then uses Geomagic Studio point-cloud processing software to extract preprocessed point-cloud data.The experimental result showed that the method can collect a large number of point-cloud data and has high measuring efficiency and precision of point-cloud data collection and procession and strong anti-interference capability.
