Digital Videogrammetry

Digital Videogrammetry is the video equivalent of photogrammetry. A video camera takes 1500 'pictures' per minute, each of which can be independently viewed, printed and measured as an individual 'photograph'. Precise digital videogrammetry is a combination of precision instruments with one or more video cameras and a laptop computer. The pictures taken are recorded as digital images on the laptop, that can display combinations of the images on screen in real time. In this way the view through one or more theodolites, together with the theodolite readings and other information, can all be reviewed and recorded simultaneously at relatively high speed and then examined in detail at leisure.
