Embodiment 1

[0060] Embodiment 1, the present invention proposes a method for monitoring cage net damage based on monocular space-time continuous images, including an unsupervised learning network model training step and a net clothing image processing step, wherein the unsupervised learning network model training step, Used for training to obtain an unsupervised learning network model;

[0061] Net clothing image processing steps, such as figure 1 shown, including:

[0062] S1. Use a monocular camera to scan the net clothing to obtain multiple spatially continuous net clothing partial images; figure 2 As shown, it is a netting model, assuming that the netting is a standard cylinder, and the monocular camera scans and takes pictures along the surface of the netting;

[0063] S2. Input the net partial image into the unsupervised learning network model to obtain the depth of field with different semantics in each net partial image, separate the pixels whose semantic meaning is net, remove...

Embodiment 2

[0124] Embodiment 2, this embodiment proposes a cage net clothing damage monitoring system based on monocular space-time continuous images, such as Figure 9 shown, including:

[0125] Central axis 11, it is arranged on the center of net clothing 12 along vertical direction;

[0126] a beam 13, which is arranged horizontally and is rotatably connected with the central shaft 11;

[0127] A first driving mechanism (not shown in the figure), which accepts the control of the control module, is used to drive the beam 13 to rotate around the central axis 11;

[0128] Telescopic arm 14, one end of which is fixed on crossbeam 13 near one end of net clothing 12, and the length can be stretched along the vertical direction;

[0129] Monocular camera 15, which is fixed on the free end of telescopic arm 14, is used for shooting net clothing 14;

[0130] The control module 16 receives the image information sent by the monocular camera 15, and monitors the damage of the net clothing acco...

Abstract

The invention discloses a net cage netting damage monitoring method and system based on monocular space-time continuous images. The method comprises an unsupervised learning network model training step; a netting image processing step, comprising the following steps: (1) scanning a netting by using a monocular camera to obtain a plurality of spatially continuous netting local images; (2) inputtingthe local image of the netting into an unsupervised learning network model to obtain a preliminary image of the netting; (3) repairing and splicing the shielded area in the preliminary image of the netting to obtain an overall image of the netting; and (4) carrying out damage detection on the whole image of the netting. According to the netting damage monitoring method, the whole process is automatically detected and analyzed, manpower consumption in netting damage detection can be effectively reduced, and the netting damage condition can be monitored in real time with high precision. And compared with an underwater robot, hardware configuration required by the method is simpler, and the cost is low.

Description

technical field [0001] The invention belongs to the technical field of image processing, and in particular relates to a method and system for monitoring damage to cage netting based on monocular space-time continuous images. Background technique [0002] Fishery is an important part of my country's agriculture and national economy. With the growth of population and the improvement of national living standards, the demand for fishery products is also increasing, especially the demand for high-quality marine aquatic products is growing rapidly. Fish cage culture has developed rapidly, especially the scale of deep-water cages has gradually increased. Large-scale and large-scale production of deep-water cage culture is an inevitable trend. However, it is difficult to find out in time when the deep-sea net cage is damaged, which will easily cause a large number of cultured fish to escape, causing huge losses to the farmers. Therefore, net clothing safety monitoring has become a ...
