Abstract
The orthophoto with refined details and higher accuracy is important for urban geographical information system. The traditional differential rectification did not consider the height information of buildings when dealing with imagery over urban areas, resulting in buildings having relief displacement and cannot be located at their true geographical positions. In this study, a digital building model (DBM)-based procedure for automatic true orthophoto generation is proposed to solve this problem. This procedure includes three major steps: (1) traditional orthophotos generation, (2) buildings relief correction, and (3) occlusion detection and compensation. In our method, the relief displacements for buildings are corrected and occlusions are detected by using the backprojection and intersection method based on vector DBM surface polygon. True orthophotos are obtained with the compensation of occlusions. Experimental results show that the generated true orthophotos can achieve root-mean-square errors of 0.149 and 0.061 m on the
