Problems solved by technology

[0007] The object of the present invention is: in order to solve the low investigation efficiency caused by diving sampling by divers in the prior art, the high cost of investigation work, and the difficulty in detailed investigation of the distribution pattern of indicators such as the species, quantity, and size specifications of large-scale benthic organisms in marine pastures on the seabed Problem, the present invention provides a remote survey equipment and method for large-scale benthic organisms in marine pastures. It mainly uses underwater remote video cameras to shoot images of the distribution of benthic organisms on the seabed, and identifies, measures and records species of benthic organisms on the seabed, Quantity, size, specification, and distribution pattern, complete the survey of macrobenthic organisms in marine pastures, improve the current technical level of macrobenthos surveys in marine pastures, improve the efficiency of macrobenthic investigations in marine pastures, and strengthen the supervision of macrobenthos resources in marine pastures Level

Embodiment approach

[0063] As the first embodiment of the present invention's marine ranch macrobenthos remote survey equipment, the mobile terminal 4 includes a movable server and a display screen, which can dynamically display and store the submarine video information captured by the underwater remote video camera 6 .

[0064] As the second embodiment of the large-scale benthos remote survey equipment in marine pastures of the present invention, the video information remote receiving PC 3 is a desktop computer, which is connected with the mobile terminal 4 through microwaves, and is used to store the underwater remote video camera 6. Submarine observation video data, and install video data processing software and image processing software to analyze and process submarine video data and images collected by underwater remote video cameras.

[0065] The present invention also provides a method for remote investigation of macrobenthic organisms in marine pastures, using the above-mentioned method fo...

Abstract

The invention relates to the technical field of marine fishery resource investigation, in particular to a remote survey equipment and method for large-scale benthic organisms in marine pastures. Several grid lines are set on the plexiglass sealing cover to form several irradiation grid areas, and the Under the action of the lamp tube, several grid projection areas are correspondingly formed on the bottom surface of the underwater remote video facility bracket, which are photographed by the underwater remote video camera, and the video information is remotely received by the PC to analyze the water quality of each investigation point. Download the remote video image, respectively observe and record the species name and quantity of the marine pasture macrobenthic organisms in each grid projection area, which solves the problem of low investigation efficiency in the prior art, and the present invention does not require divers Diving sampling can greatly reduce the cost of survey work on benthic organisms in marine pastures, and also improve the precision of survey work.

Description

technical field [0001] The invention relates to the technical field of marine fishery resources survey, in particular to a remote survey device and survey method for large-scale benthic organisms in marine pastures. Background technique [0002] Marine ranching is a new marine fishery production model that combines the functions of environmental protection, resource conservation and sustainable fishery output, and has been valued and applied by more and more countries. At present, my country has approved the construction of 5 batches of 110 national-level marine ranch demonstration areas, with a total sea area of ​​200,000 hectares. Large marine benthic organisms are important fishery resources in marine ranching and also an important part of marine biological resources. The macrobenthic animals in my country's marine pastures mainly include sea cucumbers, abalones, lobsters, sea urchins, conchs and scallops. [0003] The current investigation method of marine benthic orga...
