HighStitch: High Altitude Georeferenced Aerial Images Stitching for Rocking Telephoto Lens

A georeferenced orthophoto built from aerial images is the basic resource for various of remote sensing applications. As traditional low flight altitude aerial photographic survey is hard to handle large areas, higher altitude brings better survey efficiency, and a telephoto camera is required to ma...
