本系统对采集到的齿轮实物图进行处理，通过对比多种边缘检测方法，选择了效果较好的高斯拉普拉斯方法进行齿轮的边缘检测。
Gear's image is processed by system and several diversified algorithms of edge detection are compared, LoG algorithm is chosen in paper because of its good results.
首先对图像进行中值滤波去除噪声，然后用高斯—拉普拉斯算子提取边缘，这种边缘检测方法的效果很好。
First, do median filter to image in order to wipe off noise, then make use of Gauss-Laplace operator to pick up edge. The result showed the kind of edge detecting method has good performance.
