Stereo camera accuracy testing with IMR

Mohn Technology is currently testing an underwater stereo camera system with Institute of Marine Research. The accuracy testing performed this time was done by comparing the distance between the white dots on a calibration bar to the camera based measurements. The distance between the dots is 596,4 mm, and most measurements had a margin of error around 0,5%

These kinds of tests are important to verify the hardware accuracy under different conditions and improve software. Underwater machine vision measurements are more complex due to the poor light and contrast. The underwater stereo camera is a compact version of what is used in the autonomous Fish Research System (FRS)
