Underwater floating light trap for capturing small aquatic organisms
The invention relates to a method for non-contact detection of the health status of fish (1) in their natural environment, in which the field of view (2) of a 3D camera (5) and the field of view (2) of a high-speed camera (6) are directed into the monitored area (3). resolution. The fields of view (2) of the two cameras (5, 6) at least partially overlap. Subsequently, a primary image is taken by a 3D camera (5), for which the presence of at least one fish (1) in a suitable position is verified in a computer (4). Then, at least one secondary image is taken by a high-resolution camera (6), on which the recorded fish (1) is located in a suitable position by a computer (4) using data from the processing of the primary image. The selected secondary image data set with the recorded fish (1) is analyzed on a computer to identify the recorded fish (1), and the selected secondary image data set with the recorded fish (1) is analyzed on a computer to find visual symptoms (7) accompanying the health change. recorded identified fish (1).
