摘要

The main purpose of this study is to explore the potential of normal digital video camera for virtual 3D City modeling. For any photogrammetric project work, image acquisition is the main issue. Co st, time, and success of any close range photogrammetric project is mainly dependent on image acquisition method. Video recording is an easy way to capture the large city area in less time. In the present study a simple method for 3D scene reconstruction by using digital video camera is develo ped for virtual 3D City modeling. The digital video camera used was Sony DSC HX7V camera for video recording. From this video data, image frames created and identified for suitable image frames for image based modeling. After processing some intermediate products were obtained and finally textured 3D model of area was created. Stud y area was Civil engineering department, IIT-Roorkee, India. Agisoft Photoscan software was used for this work. This paper covers the methodology, result, discussion, conclusion, advantages and limitations of the method
