| Popis: | The real and measurable model is helpful for structure simulation. Photogrammetry technology provides a new method to model a structure by photos. This article explored the feasibility of photo-based 3D modeling for the arc bridge structures by ordinary digital camera. Firstly, the preparation processes before modeling were introduced, that included camera calibration, designation of shooting program, how to take photos and plan measurement. Secondly, photo orientation and modeling process were introduced, too. A measurement test was put forward to get some good points to enhance the accuracy. By comparing the measurement accuracy of modeling results from the four photos and eight photographs, some proposals were presented to improve the accuracy. The 3D model can be integrated with the loading conditions and material properties, to provide the detailed data for analyzing the structure. |
