3D-modeling of Norrköping

Abstract: The interest for a detailed and high solution city model has been large within the project” Optical signature analysis” at the department for Sensor Technology in FOI, Linköping. Thus, a textured 3D-model over Norrköping is needed, which later can be imported into simulation software to study optical signature in urban environment. The aim with this thesis work is to be able to use the result as a multi-used 3D-model within applications of the Swedish defence force for future usage. It is important to have a realistic representation of the environment so that the exercises can be planned and analyzed at the current position. For the final result to be as good as possible, the thesis work has been concentrated and limited into a smaller area, i.e. the quarter of Svärdet at Nya torget. Thereafter the thesis work has been divided into different stages: photographing, laser measurement, photomontage, modeling and texturing. One of the most important and extensive stages is to make the high solution and detailed texture pictures with photomontage. These pictures are first created with photographing and then be performed into panorama pictures. Further, the thesis work has been performed with suitable software, such as 3ds Max and Photoshop CS. The finished 3D-model will be supplied as a 3ds-file and max-file, where the textured pictures from the model have been moved into a folder to facilitate future works, for example in classification of texture-pictures.
