摘　　要：在网格应变测量中提取网格,先对图像进行边缘检测,然后求出边缘图像中每个网格的质心,利用质心重组应变网格并计算网格应变。以Android系统智能手机为平台,对印有应变网格的零件进行拍照,并在智能手机上实现图像网格质心的提取,完成网格应变测量。A new method of grid extraction has been designed for grid strain measurement to implement image edge detection by using the image processing technology.Then,the centroid of each grid is calculated,and the grid is rebuilt with the centroid and finally the strain of grid is measured.Intelligent mobile phone equipped with Android system is used to replace the computer with camera,CCD unit and PCI bus frame grabber.The whole process is realized in the mobile phone,including photographing with the on board HD camera,the subsequent image processing process and grid centroid extraction.
