Scaling Camera

The Tritech Image Scaling System (ISS) can measure the size of objects underwater.
 
 
The system consists of a PAL colour zoom video camera with six lasers. Four of these lasers provide parallel beams. The other two are mounted at predefined angles to provide reference points. To measure an object, a video screen capture has to be taken with the lasers pointed at the object. The screen capture is then imported into the ISS-SOFT package after the dive, where the image can be analysed and measurements can be taken Depending on the image quality and camera angle, objects can be measured to within one millimetre.
