Pelagic fish project with IMR

Mohn Technology and the Norwegian Institute of Marine Research (IMR) are working together to create new tools to improve the accuracy of purse seine fisheries. The project consists of many technological advancements, and Mohn Technology will contribute with our machine vision and remote controlled vehicle knowledge.

The results will help the fishing industry increase their pre-catch knowledge about the fish and improve profits. The tools can also be used by researchers who wish to learn more about the pelagic fish population.

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)
