Abstract Research purposes: The measurable 3D stereo model, as a new expression tool for the geographic information, is very important to the railway alignment and engineering design. But the traditional stereo model is a single photo pair model with the complicated calculation of the coordinates and this limites its applications. The digital stereo orthoimage method presented in last years breaks through the limitation of the single photo pair model, but the calculation process of accurate coordinates is still complex. On the premise of ensuring the accuracy, the calculation method should by simplified and the application of the large sight stereo model should be sped up. This paper presents a new set of methods for building and measuring the model.
Research conclusions: The experimental results show that the large sight stereo model build with this method has good visual effects. Its calculation method is simple and easy to realize. Its measurement accuracy is good as the measurement accuracy of the digital photogrammetric workstation in same scale. So it is available for the railway alignment and engineering design, and with it the design works can be directly done in the 3D stereo environment.
