摘要：Mobile mapping is a hot issue in the communities of photogrammetry and computer vision nowadays. Mobile mapping systems represent a significant advance in integrated, multi-sensor digital mapping technology, providing an innovative path towards rapid and cost-effective collection of high-quality and up-to-date spatial information. Therefore how to acquire geometric and texture information from the images for reducing human operations and enhancing efficiency is a challenge in mobile mapping data processing. In this paper, the rendering of building texture from land-based video is implemented. Firstly, some preprocessing of images is implemented. The occlusion of tree is removed because it goes against the extraction of lines from buildings. Close-ranged DC images are greatly affected by lens distortion, so lens distortion is calibrated and the influence is eliminated accordingly. Then, Land-based Video image sequences are automatically rectified to eliminate nonlinear distortion thanks to the large obliquity of the posture of DC. The building texture is finally mosaic from rectified image sequence and refined by the process of texture analysis
