This interesting and detailed architectural project was carried out by Jan Wesbuer in his diploma at the department of civil engineering at FH Aachen (Aachen University of Applied Sciences, Institute of Surveying Sciences).
The Emmaburg is one of the most important historical buildings in East-Belgium. It consists of different buildings - segments like a donjon, a chapel, living quarters and buildings for farming. In this photogrammetry project the chapel was measured to create a photorealistic and measurable 3D model.
The project consists of 104 photographs taken with a Nikon Coolpix 5700 with 35mm and 107mm focal length lenses. The project had 16 control points (to support measuring strength), over one thousand points, one thousand lines, over two hundred NURBS curves and over 900 surfaces.
The project was exported into VRML with 22 MB of texture and imported into Cinema 4D to make a flight around the building. Other products such as ortho-photos and stereo views were created. Beside these products, the authors were also interested in the accuracy of close range photogrammetric methods and checked the accuracy of the PhotoModeler predictions with a Zeiss Trimble 3305 DR total station. The measurements were all in the expected range of prediction.

PhotoModeler Pro 5 was used to create this model of the Bank of China Tower in Hong Kong. The 368 metre skyscraper is one of the most recognizable landmarks in Central Hong Kong. It has a unique sectional design, providing a different perspective from each side of the building.
Producing models of tall structures such as this building presents a number of photography challenges.
1) Obstructions: Like many big cities, Hong Kong is dense and it can be difficult to take photos than capture full and unobstructed views of the building.
2) Elevated shots: it is not always possible to gain access to elevated positions for taking photos. Most photos will have to be taken from easily accessible positions at ground level.
To compensate for these limitations, extra photos were taken, with some sections of the building photographed in overlapping sections to ensure proper coverage. This resulted in 27 photographs being used, which is a large amount to work with in a PhotoModeler project. To use this high number of photos efficiently, PhotoModeler's Photo Sets were used to organize photos in groups for use in marking, referencing, and troubleshooting. The Photo Sets also assisted in assigning the best quality photo textures for the model.
The building itself contained many identifiable features that could be marked and referenced in PhotoModeler. Its triangular sections provided many corners, while the criss-cross bars on the sides of the building provided additional features to mark. They are also important to the model because they represent important structural features, as these bars are major components of the weight bearing structural design.
A number of different PhotoModeler tools were used to complete the model - such as points, lines, surfaces, surface draw, referencing, projections, photo sets and cylinders. The final model was a detailed wireframe CAD model, that captured the full building and its features in detail. In addition, photo-textures were added for a complete 3D model.
The project was completed by SJF Marketing, using 25 photos taken with a 2.1 Mega Pixel Canon Powershot digital camera.
PhotoModeler Pro 5 was used to create this model of a wooden cabin in British Columbia, Canada. The cabin is a complex object to model but using PhotoModeler's range of modeling tools and proper photograph coverage, the project was completed in detail.Architecture 3D Model
The realistic 3D result made use of PhotoModeler's enhanced surfacing and photo texturing tools. The project was completed by Eos Systems, using 351 3D points on 14 photos taken with a 2.1 Mega Pixel Toshiba PDR-M4 digital camera.
In 2002 the 8 metre, 70 ton Merlion, the icon of Singapore, was moved from its existing location at the mouth of Singapore River to a new location about 230m away at Marina Bay. Precise measurement and documentation were required in case any damage was sustained during the difficult move that involved crane and barge transport.
The statue was surveyed, documented and modeled by a team of surveyors led by Loi Hwee Yong of Presentus Pte Ltd. (Email: loihyong@cyberway.com.sg), Singapore. Over 20,000 3D points were generated within PhotoModeler to create this incredibly detailed model from about 200 photos. The Merlion was reopened to the public on September 15, 2002 - 30 years after its first opening at its former site. For more information on this project, please view the Documentation of the Merlion for Relocation ( 1.34MB pdf) file.
This 3D model of Lucerne's historic town center was created for use on a website to enable potential visitors to experience a realistic on-line tour. The tour provides a much better perspective of the area than can be obtained with a simple map. The revenue for the site is provided by merchants who pay to have their stores featured as part of the model.
The 50 buildings included in the model meant this would have been a time consuming and very expensive process using traditional surveying methods. PhotoModeler provided a more efficient means of creating an accurate and visually realistic model from about 500 photos, at a fraction of the cost.
The client was so pleased with the results that Architect Olivier Hess of Archiscan in Belgium has been asked to model another 1000 buildings. He can be reached at info@archiscan.com.
