| Nowadays building three dimensional models using a sequence of images of the scene is an important issue in close range photogrammetry known as videogrammetry. In this paper, we propose an efficient absolute orientation of video frames method for urban 3D reconstruction and mapping. Generally, we have five steps for 3D reconstruction from video sequence: camera calibration, key frames extraction, relative orientation of key frames, absolute orientation of key frames and dense 3D reconstruction. We suppose the calibration step and key frames extraction step are done beforehand and our purpose is absolute orientation of video frames with an effective method. The method uses videogrammetric solution in combination with surveying for absolute orientation. After relative orientation of video frames and creating an adjusted model from the scene, absolute orientation is done using the control points just in first and last frames. The results in real scene shows the efficiency of the method. |
