摘要
将数字图像处理技术应用于叠栅条纹测量物体三维形状,使用Inter公司的开源视觉库OpecCV,经过灰度化、锐化和去噪、叠加虚参考光栅对图像进行处理,简化测量过程,提高测量速度和精度.
The 3-D shape of an object measured by moiré fringes was improved using the digital image processing techniques.The open source vision library developed by Inter company,OpecCV,was used.The image was processed by grayscaling,sharpen,denoise and composite virtual reference grating.The experimental process was simplified,and the measuring speed and precision were improved.
