We describe a method of automated reconstruction of buildings from a set of uncalibrated photographs. The method proceeds in two steps (i) Recovering the camera corresponding to each photograph and a set of sparse scene features using uncalibrated structure from motion techniques developed in the Computer Vision community. (ii) A novel plane-sweep algorithm which progressively constructs a piec...

The current process of asset creation in digital multimedia applications, such as movies and video games, requires tedious amounts of work. The average pipeline for creating one character model, for instance, takes an average of two weeks for the studio to implement, while still struggling to pass the uncanny valley for photorealistic rendering. Duplicating models from the real material world c...

Digital orthoimage compose an efficient and economic way for the representation of two-dimensional texture information. This kind of information is functional when the user has to evaluate, analyze or measure the objects presented in the image. If the projection has to be performed on a single plane and the form of the object is not rough, the process is simple and well-known as simple rectific...

Automatic camera calibration via self-calibration with the aid of coded targets is now very much the norm in closerange photogrammetry. This is irrespective of whether the cameras to be calibrated are high-end metric, or the digital SLRs and consumer-grade models that are increasingly being employed for image-based 3D measurement. Automation has greatly simplified the calibration task, but ther...

As a component of the overall traffic incident management process, 3D measurement for accident reconstruction has gained increasing importance over recent years. Digital close-range photogrammetry displays many attributes which make it a well-suited technology for this purpose. However, traditional close-range photogrammetric approaches can pose difficulties. These include the predominance of n...

A procedure for an automatic search and measurement of artificial targets in digital images for elose-range photogrammetric applications is presented. Photographs taken with a sem i metric 6x6 camera were digitized by the "ASTROSCAN" at the Sterrewacht Leiden. The especially designed targets contain a circular barcode for automatic identification. It is shown that this procedure improves both p...
