Study on Data Registration of Subdivided Shapes in Optical 3-D profilometry
摘要
根据空间坐标组合变换原理,提出在三维形面相邻子区域重合区人为引入空间非共线三点以实现测量对象全形面数字化的方法,分析了测量数据的合成精度,并以光切法三维测量系统作为应用对象进行了实验研究.结果表明,利用该方法实现三维形面分区域测量及后序多片数据拼接,具有速度快、精度高、可操作性强等特点.
Abstract
Based on the combined transformation theory of the space coordinates, a scheme, which introduces three non co-linear marked points in the public areas of the adjacent subdivided shapes to digitize the whole profile, is proposed. The blending accuracy of the result data is analyzed and a verification about this is done in light-sectioning measurement system. Experimental results show that this approach can realize the subdivided shapes measuring and data registering as the features of rapid speed, high accuracy and simple operation in optical three dimensional profilometry.
