摘要
在线结构光测量系统中,光条中心的准确提取是影响整个测量系统精度的关键因素之一。由于被测物体表面的性质等系统噪声的影响,使得精确提取光条中心存在一定的难度。采用了抛物线拟合法和基于光条骨架的方向模板法对采集的光条图像进行光条中心提取,实验结果表明当光条图像的曲率较大时,基于光条骨架的方向模板法能够有效、准确的提取光条中心。
In the field of linear structured light measurement system,the extracting technology of light stripes center is a key factors which affects the whole system＇s precision.However,it is difficult to do,because of the system noise effect from the measured surface.This paper uses the parabola fitting method and direction masks method based on strip skeleton to extract the light stripes center.The experiment result shows that the direction masks method can extract the light strip center more exactly and effectively,when the light strip curvature is great.
