摘要

为解决叶片高精度三维轮廓测量成本高、效率低的问题

搭建了基于相位测量的三维轮廓测量系统.在完成了系统标定后

为了检验系统的测量精度

测量了一个滚珠轴承

测量精度为(0.084±10.01)mm.利用该系统从不同方向对某叶片进行了6次数据采集

采集到的数据通过数据融合得到了整个叶片的三维点云

利用整个叶片三维点云数据得到了叶片的不同截面图

为叶片型面轮廓和几何尺寸的检测提供了依据.相位测量轮廓术用于叶片三维轮廓测量

在保证测量精度的同时大大降低了测量成本

因此将相位测量轮廓术用于叶片三维轮廓测量是非常有意义的.

Abstract

In order to solve the problem that three-dimensional (3-D) profile measurement of blades was costly and had low efficiency

a 3-D profile measurement system based on phase measurement was built.After system calibration

a ball bearing was measured to test the system’s measurement accuracy and got the measurement accuracy of 0.08±0.01mm.Then data acquisition of a blade was carried on from different directions for six times.The 3-D point cloud of the whole blade was get through data fusion and got the different blade sections based on the point cloud

which provided datas for the detection of blade size and surface contours.Phase-measurement-profilometry is used in blade measurement

which ensures the measurement accuracy and has lower costs.So using phase-measurement-profilometry in blade measurement is very meaningful.
