| Abstract: | With the close-range photogrammetry technology further development,and the resolution of digital cameras general increasing, digital camera has become an important image data acquisition device. In this paper, through three-dimensional reconstruction of a small building, the two methods of fast three-dimensional reconstruction based on single image are researched, that the body and plane as the basic unit. The accuracy of reconstruction three-dimensional model is analyzed. Experiment shows that the method of three-dimensional reconstruction, high efficiency, low cost, can be used in the actual building measurements. |
