  • 摘要:This paper presents an automatic mosaicking method for generating building facade texture from a sequence of color close-range digital camera images. The constraint of straight line bundle and the constraint of known orientation of parallel lines in object space are used for determining the digital camera's parameters. Similar to the strip block adjustment used in aerial triangulation, a strip model of the least-square adjustment is used to determine the relative spatial relationship of the image sequence. Then a method similar to orthophoto generation is employed to generate the entire building facade texture. Our results demonstrated that this method is proved to be mor e applicable. Two refining strategies are presented to optimize the mosaic result. One is refining the mosaic region wher e corresponding points are difficult to be matched but ther e are plenty of horizontal lines. The constraint of correspondingly horizontal lines is introduced to implement this process. The other is refining the mosaic region by densifying the corresponding points according to the relatively spatial relationship of the image sequence
