Abstract
A method for external fish parasite monitoring in aquaculture, comprising the steps of: —submerging a camera (52) in a sea pen containing fish, the camera having a field of view; —capturing images of the fish with the camera (52); and—identifying external fish parasite on the fish by analyzing the captured images, characterized in that a target region within the field of view of the camera (52) is illuminated from above and below with light of different intensities and/or spectral compositions.
Claims14
A method for external fish parasite monitoring in aquaculture, comprising the steps of:
- submerging a camera (52) in a sea pen (40) containing fish (72, 74), the camera having a field of view;
- capturing images of the fish (72, 74) with the camera (52);
- and
- identifying external fish parasite on the fish (72, 74) by analyzing the captured images, characterized in that a target region within the field of view of the camera (52) is illuminated from above and below with light of different intensities and/or spectral compositions.
A system for external fish parasite monitoring in aquaculture, comprising:
- a camera (52)
- a lighting rig (10) comprising an upper lighting array (22), and a lower lighting array (24)
- a ranging detector (54)
- wherein upper lighting array and the lower lighting array each comprise one or more lights wherein the light in the upper lighting array has a different intensity and/or a different spectral composition than the light in the lower lighting array.
