VISIOMASTER has been developed for the purpose of eliminating the manual check of the fish that are gutted in a Kroma gutting machine. VISIOMASTER takes a picture of the belly area of ​​the fish that has just been cleaned. Before the fish leaves the gutting machine, the picture has been analyzed and decided if the fish is going to move on in the process or go past a manual gutting table. Several cameras can be mounted to the same PC. A different camera does not have to check fish, but can for example be used for sorting the fish when they enter the production area. It is possible to process with different programs for cleanliness, depending on our customer’s requirements.

From the picture made by VISIOMASTER, it is possible to determine whether there is still a residue of kidney blood, gills, heart, or other parts of intestines still in the fish, by using the developed software. During the running-in of the system, it is established how much kidney blood is allowed in the fish before it is sent to manual check. The different allowed values ​​are completely up to the customers.

The camera and lights are built inside the gutting machine. Both parts are built into a stainless-steel box. The light, which functions as a flashlight, is an LED and it is only lit in the brief time when the fish passes and triggers the sensor. To execute the picture processing a powerful industrial server is used. The server is mounted in a normal office environment at a short distance from the gutting machine. The camera and server are directly linked to achieving fast response times that are demanded from the system.
