Problems solved by technology

However, human beings stay on the bottom of the sea for a limited time, and are greatly affected by the ocean environment such as currents, water temperature and transparency. The measurement fails to meet the requirements of scientific research, and the cost of hiring divers is relatively high

Embodiment Construction

[0018] The application of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0019] refer to figure 1 , a marine benthos on-site automatic photographing and measuring device, which includes a movable support 1 and a vertical bar 2, a sample frame 4 is provided at the lower end of the movable support 1, and the vertical bar 2 is provided with a free end and a photographing end, The photographing end is equipped with an underwater camera 5, and the photographing end passes through the snap ring 3 on the upper end of the movable support 1 and is placed above the sample frame 4, and the distance between the underwater camera 5 and the sample frame 4 can be adjusted. The underwater camera 5 is connected with the line connection of the photography processing system 6 arranged outside the movable support 1 .

[0020] The camera processing system 6 is generally a portable computer, which is displayed on the computer through the Pi...

Abstract

The invention discloses a marine benthos on-site automatic shooting and measuring device which comprises a movable support and a vertical rod. The movable support is provided with a sample frame, the vertical rod is provided with a shooting end which is provided with an underwater camera, the shooting end penetrates through a clamping ring at the upper end of the movable support and then is placed above the sample frame and can be used for adjusting the distance between the underwater camera and the sample frame, and the underwater camera is in line connection with a shooting processing system arranged outside the movable support. The movable support is arranged and provided with the underwater camera, and therefore when an underwater sample is shot, the movable support is arranged on a survey station and located underwater to observe benthos in the sample frame, the vertical rod is used for adjusting the distance between the underwater camera and the sample frame, the underwater camera is used for shooting and recording the conditions of the sample and sending images to the shooting processing system, and therefore the types and the quantity of the benthos in the sample frame can be conveniently counted, sample data can be collected automatically, and the shooting processing system can be connected with a rechargeable storage battery. The device is suitable for measurement on the sea.

Description

technical field [0001] The invention relates to an on-site automatic photographing and measuring device for marine benthic organisms. Background technique [0002] Marine benthic organisms are animals and plants that live at the bottom of the ocean, including life types such as camp fixation, bottom burial, drilling erosion, bottom crawling and bottom swimming. In marine ecosystems, different benthic organisms are at different trophic levels. Monitoring the species and quantity changes of marine benthic organisms and clarifying their relationship with marine biological production and resource development are important contents of marine benthic organisms research. [0003] In order to investigate and grasp the status quo of marine benthic organisms and their habitats, the current method usually employed is to hire divers to dive into the seabed for photography and measurement. Specifically, divers took underwater cameras and rulers to the bottom of the survey site, marked ...
