Research on Image Registration of Different Wavebands Based on SIFT Algorithm

With the continuous development of space industry, the types of remote sensing data obtained are increasing. Image registration is widely studied as a key step in image applications. However, the research of existing image registration methods focuses on the same band and the same data source, and there are relatively few studies on different data sources for different bands and different angles. For the images of different wavebands obtained by different types of sensors in the same scene, this paper uses the existing SAR images and optical images of different wavebands to register the different source images based on SIFT algorithm. Experimental results show that the algorithm has a good effect in the registration work between different source images.
