A new approach towards image based virtual 3D city modeling by using close range photogrammetry
3D city model is a digital representation of the Earth's surface and it’s related objects such as building, tree, vegetation, and some manmade feature belonging to urban area. The demand of 3D city modeling is increasing day to day for various engineering and non-engineering applications. Gener...

| description | 3D city model is a digital representation of the Earth's surface and it’s related objects such as building, tree, vegetation, and
some manmade feature belonging to urban area. The demand of 3D city modeling is increasing day to day for various
engineering and non-engineering applications. Generally three main image based approaches are using for virtual 3D city
models generation. In first approach, researchers used Sketch based modeling, second method is Procedural grammar based
modeling and third approach is Close range photogrammetry based modeling. Literature study shows that till date, there is no
complete solution available to create complete 3D city model by using images. These image based methods also have
limitations
<br><br>
This paper gives a new approach towards image based virtual 3D city modeling by using close range photogrammetry. This
approach is divided into three sections. First, data acquisition process, second is 3D data processing, and third is data
combination process. In data acquisition process, a multi-camera setup developed and used for video recording of an area.
Image frames created from video data. Minimum required and suitable video image frame selected for 3D processing. In
second section, based on close range photogrammetric principles and computer vision techniques, 3D model of area created. In
third section, this 3D model exported to adding and merging of other pieces of large area. Scaling and alignment of 3D model
was done. After applying the texturing and rendering on this model, a final photo-realistic textured 3D model created. This 3D
model transferred into walk-through model or in movie form. Most of the processing steps are automatic. So this method is
cost effective and less laborious. Accuracy of this model is good. For this research work, study area is the campus of
department of civil engineering, Indian Institute of Technology, Roorkee. This campus acts as a prototype for city. Aerial
photography is restricted in many country and high resolution satellite images are costly. In this study, proposed method is
based on only simple video recording of area. Thus this proposed method is suitable for 3D city modeling.
<br><br>
Photo-realistic, scalable, geo-referenced virtual 3D city model is useful for various kinds of applications such as for planning in
navigation, tourism, disasters management, transportations, municipality, urban and environmental managements, real-estate
industry. Thus this study will provide a good roadmap for geomatics community to create photo-realistic virtual 3D city model
by using close range photogrammetry. |
