Problems solved by technology

[0002] At present, in the muddy water experiment of the tank, the most difficult thing is to measure the shape of the sand wave on the bed surface, and the shape of the sand wave has an important influence on the structure of the water flow. The related research on the water flow and the sand wave has been carried out for about half a year. century, due to the limitations of measurement methods, there has been no breakthrough in theory

Embodiment Construction

[0017] As shown in Figure 1, the underwater three-dimensional terrain measurement system of the present invention comprises: computer 5, support 8, conveyer belt 2, wheel 1, variable speed motor 3, luminous device 6 and CCD camera 7, and support 8 is framed on the water tank 4 to be measured The support at the upper end is equipped with a conveyor belt 2 on its upper end. The conveyor belt 2 is driven by a variable speed motor 3. The conveyor belt 2 is a conveyor belt with racks. The wheel 1 is a toothed wheel. The wheel 1 rolls on the conveyor belt 2 (see Figure 2 ). The light emitting device 6 is mounted on the rotating shaft 12 of the wheel 1 through a rope. Camera 7 is installed on the corresponding side of the water tank 4 perpendicular to the light surface emitted by luminous device 6, and computer 5 is electrically connected with luminous device 6, wheel 1, variable speed motor 3 and CCD camera 7 respectively.

[0018] As shown in Figure 3, light emitting device 6 comp...

Abstract

The invention relates to underwater three-dimensional topographic survey system. It includes computer, bracket, carrying belt, wheel, electric machine, light emitting device, and video camera. The bracket is set at the upper end of the tested sink. Its upper end is set the carrying belt driven by the electric machine. The wheel rolls on the carrying belt and is set light emitting device. The video camera is set the side face of the sink. The computer is respectively connected with the light emitting device, wheel, electric machine, video camera. The invention is based on digital image recognition, combines with digital videotape, laser, and image recognition, adopts CCD video camera to up-take underwater topography, uses three-dimensional digital to do reconstruction for the underwater three-dimensional sand wave model, measure under water topography real time change, and plays crucial role in current, sand wave corresponding study.

Description

technical field [0001] The invention relates to an underwater three-dimensional topography measurement system, in particular to an underwater three-dimensional topography measurement system for measuring the shape of sand waves. Background technique [0002] At present, in the muddy water experiment of the tank, the most difficult thing is to measure the shape of the sand wave on the bed surface, and the shape of the sand wave has an important influence on the structure of the water flow. The related research on the water flow and the sand wave has been carried out for about half a year. In the last century, due to the limitations of measurement methods, there has been no breakthrough in theory. Contents of the invention [0003] The purpose of the present invention is to solve the difficult problem of measuring the shape of sand wave, and provide an underwater three-dimensional terrain measurement system for measuring the shape of sand wave. [0004] In order to accompli...
