The invention belongs to the technical field of
deep sea net
cage culture observation, and relates to an abnormity detection method for a
marine culture net cage netting, which is used for detecting two states of
biological adhesion and damage of the netting, and equipment comprises an
underwater robot ROV provided with a camera and a computer. When the
marine culture net cage netting is detectedabnormally, the problems of high risk and low efficiency of
underwater detection operation are fully considered, an ROV is used as a carrier, and a visual
image measurement technology is combined to carry out abnormal alarm on common
biological adhesion and netting damage phenomena in
marine culture. According to the invention, the ROV is utilized to take a netting image; the image recognition technology of the
key frame is tightly combined with the characteristic
curve analysis method; the
underwater netting abnormity detection
system suitable for offshore net cage inspection is flexibly constructed, the reliability of ROV inspection is greatly improved, the risk of marine culture observation, especially
deep sea culture observation, is reduced, and the application and popularization of the ROV and
image measurement technology in marine culture net cage inspection are greatly promoted.
