Abstract
It has long been difficulties in aerial photograph to stitch multi-route images into a panoramic image in real time for multi-route flight framing CCD camera with very large amount of data, and high accuracy requirements. An automatic aerial image mosaic system based on GPU development platform is described in this paper. Parallel computing of SIFT feature extraction and matching algorithm module is achieved by using CUDA technology for motion model parameter estimation on the platform, which makes it’s possible to stitch multiple CCD images in real-time. Aerial tests proved that the mosaic system meets the user’s requirements with 99% accuracy and 30 to 50 times’ speed improvement of the normal mosaic system.
