The invention relates to the field of marine ranch monitoring and operation and
maintenance management, in particular to a high-resolution real-time 3D marine ranch monitoring device capable of automatically sinking, which comprises a shipborne
control system, a net cage, a sliding rail, a range gating
laser imaging device and an automatic sinking
system, and is characterized in that the range gating
laser imaging device is slidably arranged in the net cage through the sliding rail; the range gating
laser imaging device comprises a lighting unit and two
solid-state camera units, the autonomous sinking
system is arranged on the side opposite to the input ends of the
solid-state camera units, and the output ends of the
solid-state camera units are connected with the input end of the shipborne
control system. According to the invention, real-time panoramic 3D monitoring of marine ranching devices in different water bodies with different depths can be realized, dynamic capture and analysis of fishes in the ranching net cage can be realized based on the range gating
laser imaging device, and excellent data support is provided for efficient operation of the marine ranching.
