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...

In volcanic areas, where it can be difficult to perform direct surveys, digital photogrammetry techniques are rarely adopted for routine volcano monitoring. Nevertheless, they have remarkable potentialities for observing active volcanic features (e.g., fissures, lava flows) and the connected deformation processes. The ability to obtain accurate quantitative data of definite accuracy in short ti...

In photogrammetry a camera is considered calibrated if its interior orientation parameters are known. These encompass the principal distance, the principal point position and some Additional Parameters used to model possible systematic errors. The current state of the art for automated camera calibration relies on the use of coded targets to accurately determine the image correspondences. This ...

One of the most significant achievements in digital photogrammetry in the last decade is the development of large format digital mapping cameras. In addition to large format digital mapping cameras, a number of medium format digital mapping cameras systems have also been developed. At Pictometry, a medium format digital imaging system has been developed and been widely used for acquisition of b...

Photogrammetry is the art and science of deriving accurate 3-D metric and descriptive object information from multiple analogue and digital images. Recently, there has been an increasing interest in utilizing imagery in different fields such as archaeology, architecture, mechanical inspection, and surgery. The availability of reasonably priced, off-the-shelf, and high-quality digital cameras is...

We examined two image-based methods, photogrammetry and stereo vision, used for reconstructing the threedimensional form of biological organisms under field conditions. We also developed and tested a third ‘hybrid’ method, which combines the other two techniques. We tested these three methodologies using two different cameras to obtain digital images of museum and field sampled specimens of gia...
