Embodiment Construction
[0021] The present invention will be further described below in conjunction with the accompanying drawings.
[0022] combine figure 1 , the fast and robust visible light image and SAR image registration method based on structural similarity of the present invention, comprises the following steps:
[0023] Step 1, use rational polynomial coefficient RPC model to carry out coarse registration to visible light image and SAR image;
[0024] Step 2. Use the improved corner detection algorithm to detect control points in the visible light image, and select evenly distributed control points;
[0025] Step 3, using the improved direction Harris corner point histogram HIOHC descriptor for the control points in the visible light image to match the corresponding control points in the corresponding search area in the SAR image;
[0026] Step 4, removing the point pairs with matching errors;
[0027] Step 5. Estimate a geometric transformation model with the smallest error using the mat...
