A New Method for Passive Millimeter Wave Image Registration by Applying Super Resolution

The image registration between visual image and passive millimeter wave (PMMW) image is a key technology in terminal guidance and security systems, and feature-based image registration algorithm has been an effective way to align the images from different sensors. Considering the low space resolution and lack of high-frequency of PMMW image, this paper proposed a new combined image registration method with the typical super resolution (SR) algorithms to deal with the PMMW image. The result proved that SR processing could decrease localization error and raise the accuracy of registration. Our study can improve the attack accuracy of missile equipped with scene matching (visual and PMMW image matching) guidance. Furthermore, it is useful in high-accuracy image registration between images from other bands, infrared, for example.
