Semi-Automatic Orientation of Images With Respect to a Point Cloud System
Adjustment automation calibration detection matching orientation programming
2015/12/8
This paper presents the results of a master thesis in which it was tried to orient a set of images of an object to a point cloud of the same object. As test object the “Semper Sternwarte” in Zürich wa...
Results of A Performance Test of a Dual Mid-Format Digital Camera System
medium format dual-head camera direct georeferencing empirical test geometric performance
2015/11/23
The low weight and the relatively low cost of medium format digital cameras have pushed the use of those units for aerial survey. These medium format cameras are often used as secondary sensors togeth...
The 3D Photo-Logging System for Easy and Effective Recording and Understanding of Archaeological Sites
Camera phone 3D viewpoint GPS motion sensor photograph documentation
2015/11/12
A “3D photo-logging system,” a new method for recording archaeological sites, was developed. The prototype system consists of several servers running on a single machine and logging units composed of ...
