摘　　要：为实现对密集网孔尺寸的快速测量,提出一种大面积高精度平面网格尺寸快速自动化检测方法及系统。首先利用高、低双放大倍率光学同轴成像系统同时获取被测网格图像;并由图像中同名网孔计算出高、低倍图像尺寸转换比例系数,进而得到低倍图像中所有网孔的尺寸;最后通过三维运动平台实现不同位置网孔的自动化测量。实验证明该系统大幅提升了密集网孔的测量效率,最高精度达1μm,可用于试验筛检测并可实现对筛网面质量的客观综合评价。In order to realize the fast speed measurement of the mesh size,the fast speed automated detection method and system with high accuracy for the mesh size in large flat area is proposed. By adopting the optical coaxial imaging system with two of the magnification,low and high; to capture the image of the measured mesh,and calculate the conversion ratio between the sizes of images of the same mesh under different magnification,then the sizes of all meshes in low magnification images are obtained. Finally,automatic measurement of the mesh in different position is implemented through 3D motion platform. The experiments verify that the system greatly enhances the measurement efficiency of dense mesh,the maximum accuracy is up to1μm,it can be used in detection of test sieves,and realize objective comprehensive evaluation for quality of sieve surface.
