An Approach of Aerial Photogrammetry Measurement Based on 3D Model

Abstract:

. This paper introduces a new approach on measurement of aerial photogrammetry. Because of the development of stereoscopic display technology, the author wants to change 2D working environment to 3D working environment during aerial photogrammetry measuring process. The approach gives a new way to do aerial photogrammetry measurement in 3D environment. Firstly, we made image pixel data one-to-one corresponding with DEM data of the area. Then, we built a 3D model of the area. Since the one-to-one corresponding of DEM and image, we obtained photo coordinates of the target points of stereo pair on left image and right image in single click. And then, with the help of traditional theory， we finished calculation of the transforming from photo coordinate system to ground coordinate system, by which we could obtain ground coordinates of the target points. Finally, we overlapped the points which we calculated on the DLG in ArcGIS software to validate the correction of the calculation. The result shows that the precise of this approach is acceptable. At the end of the paper, the author gave some advices to improve the approach and the expectation of 3D measurement in true 3D environment.
