Abstract

Framgangsmåte for regisfrering og beregning av vekt av fisk. Det brukes et antall kamera, særlig eeD- kamera, som regisfrerer bilder av fisk som beveger seg forbi kameraene i en overføringskanal. Fisken belyses fra forskjelhge sider i overføringskanalen og det regisfreres bilder av forskjellige deler av fisken med en sekvensstyring, slik at det dannes et sammensatt billedopptak som brukes som grunnlag for beregning av fiskens vekt. En anordning for å gjennomføre måling på fisk (11) som beveger seg i en overføringskanal (12) har minst to lyskilder (14) ved overføringskanalens vegg, for belysning av fisk, samt to eller fiere kameraer (10), særiig eeD-kameraer, plassert i et tverrplan jevnt fordelt rundt omkretsen, for å regisfrere refiekser fra eller skyggebilder av fisken.Procedure for registration and calculation of weight of fish. A number of cameras, especially eeD cameras, are used, which record images of fish moving past the cameras in a transmission channel. The fish is illuminated from different sides of the transmission channel and images of different parts of the fish are recorded with a sequence control, thus forming a composite image recording which is used as a basis for calculating the weight of the fish. An apparatus for carrying out measurements on fish (11) moving in a transmission channel (12) has at least two light sources (14) at the wall of the transmission channel for illumination of fish, and two or more cameras (10), special eeD cameras, placed in a transverse plane evenly distributed around the perimeter, to record reflexes from or shadow images of the fish.
