摘要

提出了利用激光光栅投影技术对硬合金刀具磨损图像进行检测的方法。利用采集待测物体栅线图样中未变形区域包含的相位信息

使用最小二乘迭代法将数据拟合

方向最大深度参数的标准差和相对精度都小于0.01

具有较好的三维形貌轮廓检测精度。

Abstract

Image detection method for carbide tool wear based on laser grating projection is presented. Phase information in undesformed areas that belongs to object shadow and data regression with the least-squares iteration are used to obtain phase distribution parameters on the ideal reference plane. For unnecessary to collect deformed grating images of object reference plane

it reduces operation steps and takes no solution for the phase of object reference plane. Experiments show that the method realizes the on-line measurement by detecting the parameters during the time slots caused by replacing tools of numerical control machine. Also

the measurement data of maximum width

maximum area

circumference and maximum depth in

direction of wear region come to the results that measurement standard deviation and relative accuracy are no more than 0.01. Therefore

this method is a precise 3D profilometry of wear area.
