8. Photogrammetry, videogrammetry
These are the names given to techniques used to determine the dimensions, shape and positions of objects from photographed perspective views, a method very similar to triangulation.
8.1 Measuring principle
Photogrammetry is a measuring method that uses images (photographic or digital) taken from different angles to determine the dimensions, shapes or positions of objects. To do this, we use :
either calibrated cameras using flat, dimensionally stable silver film or CCD detectors for static measurements;
or cameras (film or CCD) if dynamic measurements are required (videogrammetry).
These cameras are often referred to as metric cameras. They are...
