摘要
虽然基于各种物理原理的坐标测量设备发展很快 ,测量方法朝着自动化方向发展 ,但目前机械点触发式的坐标测量机在许多情况下仍有大量应用。本文根据点触发式坐标测量机的特点 ,首先提出了坐标数据测量的布点规划原则 ,包括考虑被测物体的对称性、分区测量的规划以及测量数据的充分性和必要性原则。在此基础上 ,给出了基于人工规划的测量数据模型重建方法。应用实例中给出了对摩托车整车外形数据的采集及
Although coordinate measuring method is going towards automation, coordinate measuring machine(CMM) is widely used in a variety of situations. According to the character of CMM, we first put forward the principle of coordinate measuring,including considering the symmetry of the object to be measured, segmentation programming and the sufficiency and essentiality of the measured points. Functionalities of our model reconstruction software are described in the paper. As practical examples, the overall measured data of two types of motorcycle and the reconstructed CAD models are also included in the paper.
