This paper focuses on the use of control linear features extraction from a terrestrial laser scanning (TLS) surface to produce a good datum definition for a close range photogrammetric model. The difficulty of identifying conjugate points between both datasets is overcome by the derivation of automatic features extraction. Hence, the extracted features from the terrestrial measurements represen...

There are now available excellent integrated sensor orientation systems for the direct measurement of sensor position and attitude using GPS and IMU technology. With the maturity of these systems has come a wider interest in using this technology in an everincreasing range of applications. With a variety of applications, there becomes a need for a variety of solutions, balancing quality and cos...

Camera calibration has always been an essential component of photogrammetric measurement, with self-calibration nowadays being an integral and routinely applied operation within photogrammetric triangulation, especially in high-accuracy close-range measurement. With the very rapid growth in adoption of off-the-shelf digital cameras for a host of new 3D measurement applications, however, there a...

Novice users currently use Digital Photogrammetric Applications increasingly in order to record close range objects of great cultural value or for the monitoring of sensitive objects or procedures (industrial and medical applications). Monoscopic procedures (digital rectification) have been embedded recently, in many popular commercial applications. Also, CAD and CAM applications are gaining ev...

Close-range photogrammetry is increasingly being employed for 3D measurement and modelling across a host of application areas. Consumer-grade digital cameras are becoming ubiquitous, and ‘professional’ digital cameras are becoming less expensive. Thus, access to suitable imaging technology for 3D measurement and subsequent model building and visualisation is now open to all. Access to suitable ...

In close-range images, normally a large number of geometrical features is available. For photogrammetrists, the detection of shapes such as straight lines is very useful. These features are very helpful for further photogrammetric work, such as sensor calibration, image orientation, DTM generation etc. Hough Transform (HT), is such a powerful tool for detecting predefined shapes (i.e. lines, el...
