3D models obtained with advanced survey techniques such as close-range photogrammetry and laser scanner are nowadays particularly appreciated in Cultural Heritage and Archaeology fields. In order to produce high quality models representing archaeological evidences and anthropological artifacts, the appearance of the model (i.e. color) beyond the geometric accuracy, is not a negligible aspect. T...

Digital Photogrammetry is the quality leap in the means, ability, efficiency and agility of spatial information acquirement. Digital Photogrammetric Workstation (DPW) is the mainstream product of Digital Photogrammetry System. Nowadays DPW plays important roles in acquiring spatial data. With the emergence of high resolution sensor, such as IKONOS, QuickBird, SPOT5 and ADS40, the traditional DP...

The Institute for Photogrammetry at the University of Stuttgart has made substantial contributions to photogrammetry since its launch on April 1st, 1964, first under the supervision of Fritz Ackermann. Since June 1st, 1992 Dieter Fritsch suceeded and continued the profile in photogrammetry, but started R&D in remote sensing and geoinformatics as well. In the following some highlights of the las...

A calibration target can be imaged to provide correspondences between points in the image and points in space. It is, however, generally impractical to position the calibration target accurately with respect to the camera coordinate system using only mechanical means. As a result, the relationship between the target coordinate systemand the camera coordinate system typically also needs to be re...

Close-range photogrammetry is based on the acquisition of imagery to make accurate measurements and, eventually, three-dimensional (3D) photo-realistic models. These models are a photogrammetric product per se. They are usually integrated into virtual reality scenarios where additional data such as sound, text or video can be introduced, leading to multimedia virtual environments. These environ...

The aim of this paper is to present a method that can be used for getting better point cloud by structured light photogrammetry. The data is from the project of 3D reconstruction of old Beijing model. The object we scanned is the 1:1000 model of old Beijing city of 1950’s. The main contents of the model are a large number of building and house models. The distinguishing feature of structured li...

With the ever wider adoption of spatial information analysis, there has been an increasing awareness of the importance of 3D data acquisition systems to support traffic accident reconstruction and forensic analysis. In an application such as accident reconstruction, GIS and CAD systems have limited utility without the underlying data. Digital close-range photogrammetry displays many attributes ...

Inverse Photogrammetry is used as a tool for visualizing projected developments or past situations within an existing environment. Usually traditional photogrammetric practice is followed with respect to data input, processing and output of inverse photogrammetric products. Since the purpose is visual inspection and overview rather than strict metric needs, fast and cheap methods for both the d...

Digital airborne cameras play a significant role for aerial Photogrammetry development from analog to full-digital age. Because of the gap between digital sensor performance and Photogrammetry request, digital airborne also becomes the bottleneck of full-digital approach. In this paper, we present a design of twice-imaging airborne camera system with distributed sensors based on film camera, an...
