A Novel Method of Three Dimensional Profile Measurement
一种新的三维轮廓测量方法

A method of a practical and effective optical-electronic three dimensional profile measurement is proposed in this paper.The method,based on laser triangulation,takes use of low-pass filter and changing threshold and barycenter to get the central line of light section.Not only fast is the processing velocity,but also it can get rid of the noise influence and work out the accurate position of the central line of light section.Finally,a linear equation between the object and image is successfully concluded which solves the problem of system calibration and realizes the profile measurement.
