摘要
提出了一种基于IMAQ的孔径检测方法,首先对图像进行灰度变换、同态增晰、平滑、锐化等预处理得到清晰的轮廓,并通过坐标校正获得坐标校正系数,最后利用软件寻找圆周边缘实现孔径检测。
It introduces a method to measure the pore diameter based on IMAQ. This can obta in clear outline with image pre-processing such as gray and scale transform, def inition enhancing, smoothing and sharpening, revising with coordinate correction . It develops the system to realize measurement of pore diameter from the circul ar edge.
