Calibration based on VIOSO technology requires a suitable camera connected to the computer. The following cameras can be used:
Webcams ...are usually connected via a USB port and should work if the automatic control system can be disabled.
DV video cameras ...are connected via Firewire and, in view of the low resolution, offer very good geometry connection.
HD video cameras ...can be used if the computer has a video input card whose driver supports a DirectShow.
Industrial HD cameras ...are connected via USB or network cable. The latter makes the setup location largely independent of camera and computer and is an interesting option. Such HD cameras are produced by IDS, for example. See www.ids-imaging.com.
A precondition for successful calibration is always manual adjustability of white balance and exposure. The better the quality of the camera, the better are the calibration results to be achieved.
