A Novel Method for High Resolution Image Positioning

A novel technical way to solve the problem of high resolution images positioning is proposed. The novel method utilizes only available small-scale topographic map and multi-resolution images without Ground Control Points or large scale topographic map or GPS and IMU data. The first step is to perform rectification and positioning of lowest resolution image by small-scale topographic map, wherein the matching of corresponding linear objects is explained and the algorithm is developed. Then, the image pyramid is to perform image matching layer by layer by Least Square Matching Method until the highest resolution image at the image pyramid top is rectified and positioned. Differential rectification is also discussed to reach the conclusion that DEM come from small-scale topographic map meets the requirement of planar positioning of high spatial resolution images.
