摘要
应用Harr_Gaussian小波变换对图形图像的边缘进行频域分析 ,建立边缘测量的物理模型 ,并用带宽匹配方法和远心测量光学系统 ,在大景深物体测量中获得准确的结果 .
The Haar-Gaussian wavelet transform is applied to analyze the pattern edges in the frequency domain and to establish a physical model for the edge detection. The bandwidth-matching algorithm is proposed. A telecentric optics is used to achieve a high-precision edge detection results with large-depth of focus.
