Wave video measuring device and method

Abstract

The invention discloses a wave video measuring device and method in the technical field of marine observation. The device comprises a video image acquisition module, a data transmission module, a datareceiving and processing module, a wave parameter display module, a floating body moored on the sea surface and a calibration plate. An existing wave measurement method is improved. A left industrialcamera and a right industrial camera are used for synchronously collecting water surface preset floating body motion sequence images. An image recognition processing method is used for extracting animage coordinate system floating body center, three-dimensional coordinates in a floating body world coordinate system are calculated on the basis of a binocular vision photogrammetry principle, and then wave parameters are inverted according to sea wave observation related requirements in ocean observation standards. The invention has the advantages of being convenient to operate, simple and reliable in algorithm, low in cost and high in measuring precision, low-cost, high-precision, large-range and long-time continuous measurement of wave parameters can be achieved, and the measuring deviceand method have wide application prospects in the field of ocean wave observation.

Description

technical field [0001] The invention relates to the technical field of ocean observation, in particular to a wave video measurement device and method. Background technique [0002] Marine observation technology is an important technical support for the development of marine resources and the protection of marine rights and interests, and is of great significance to my country's coastal defense construction and the development and utilization of marine resources. The measurement of ocean wave parameters is very important to marine activities such as marine transportation, exploration and development of offshore oil and other minerals, marine fisheries, marine engineering, and maritime military activities. [0003] Traditional ocean wave parameter measurement methods include pressure wave measurement method, acoustic wave measurement method, wave trace buoy method and radar measurement method, etc. The above traditional wave measurement methods have complex structure, single f...
