Embodiment

[0034] The camera mounting device 2 and the light mounting device 3 form an included angle of 130 degrees and are connected by a flange. The traction ring 1 is circular and is located at the top of the camera mounting device 2. It is used to connect with the wire rope of the winch on the ship and pull the front of the shooting equipment. Row. The camera fixed frame 12 and the light fixed frame 13 are composed of corrosion-resistant metal pipes, and the joints are welded. The camera fixed frame 12 is triangular in shape, the bottom side is 180cm long, and the height is 110cm. The corrosion-resistant metal is welded at 1 / 3 of the height from the top. The pipe is used for the installation of the main underwater camera, and a 20cm connecting pipe is protruded from the bottom edge to 1 / 4 of the bottom corner to weld the flange. The light fixing frame 13 is a long trapezoid, with a waist length of 100 cm. It is welded with flanges at the two bottom ends, and the corrosion-resistant ...

Abstract

The invention relates to the technical field of shooting, in particular to dragging type water bottom shooting equipment. The dragging type water bottom shooting equipment comprises a camera carryingdevice, a lamplight carrying device, a main underwater camera and an underwater photography lamp. A traction ring is arranged at the upper end of the camera carrying device, and the lower end of the camera carrying device is connected with the lamplight carrying device. The area between the camera carrying device and the lamplight carrying device is a shooting area. The main underwater camera is arranged on the camera carrying device and used for shooting the shooting area. The underwater photography lamp is arranged on the lamplight carrying device and used for providing a light source for the shooting area. The water bottom shooting equipment is in a dragging type, image shooting is stable, the image area is fixed, a large number of continuous seabed images can be obtained, and the dragging type water bottom shooting equipment can be used in the research and survey of ocean demersal creatures.

Description

technical field [0001] The invention relates to the technical field of photographing, in particular to a towed underwater photographing device. Background technique [0002] The existing underwater shooting equipment used for the investigation of marine benthic organisms can be divided into two categories: man-made control and automatic control. Artificial control refers to divers carrying underwater cameras and underwater cameras to dive into the seabed for shooting. The disadvantage is that artificial diving depth and time are limited. Automatic control refers to underwater robots and deep submersibles diving into the seabed for shooting. These devices can guarantee the depth of the dive, but cannot guarantee the stability of the shooting area, cannot carry out quantitative research, and it is difficult to obtain continuous video and image data. At the same time, due to its high cost and inconvenient portability, it is difficult to apply it to the investigation of marine ...
