A New Method for Building Panoramas from Uncalibrated Photographs
Xiangxu Meng · Journal of Engineering Graphics · 2002
In this paper a new method is presented to build full view cylindrical panorama from a group uncalibrated photographs. The photos can be taken naturally with an ordinary digital camera supported by a tripod at an (approximately) fixed location. Such photos usually have large perspective distortion, small overlap, brightness difference, small concentric errors and camera rotations. These characteristics make both image alignment and panorama building more difficult than using photos taken by cameras calibrated by special equipment. Simple registration techniques cannot be applied directly to align such images. The novel image registration approach based on feature matching scheme is proposed in this paper. The panorama can be build by two steps: image registration and brightness adjustment. Experiments show that our methods yields good results and has higher computing speed. The method has been practically used in digital museum project.
