Embodiment Construction

[0048] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0049] Experiments are carried out according to the ship-mounted field of view adjustable sea surface observation device and method of the present invention, specifically comprising the following steps:

[0050] 1) Synchronize the time of the high-definition camera 4 and the shipboard positioning device 7:

[0051] Synchronize the time of the shipboard positioning device 7 to the system time of the satellite positioning system provided by the positioning system, and update the system time of the high-definition camera 4 to the time of the shipboard positioning device, so that the two keep time synchronization.

[0052] 2) Device installation and measurement:

[0053] Secure the securing mechanism to the vessel. The fixing mechanism provides two kinds of fixing methods, vertical and horizontal, and can be fixed vertically on the side of the ship according to the nee...

Abstract

The invention discloses a ship-mounted sea surface observation device and method with adjustable field of view. Through the design of ship-mounted positioning device, high-definition camera and fixed mechanism, a ship-mounted sea surface observation device and method with adjustable field of view is established, which is realized through steps such as time synchronization, device installation, field of view adjustment, observation and information processing. The invention is based on high-definition camera technology and high-precision positioning technology, and designs a fixed mechanism with adjustable field of view, proposes an information processing method, and realizes sea surface observation and area estimation. The invention can exert great practical value in the on-site positioning observation and area estimation of marine phenomena and processes such as sea surface red tides, oil spills, fronts and underwater reefs.

Description

technical field [0001] The invention belongs to the field of marine observation, and specifically relates to a sea surface observation with an adjustable field of view through shipboard positioning, high-definition camera and fixing mechanism, etc., and performs positioning and measurement of roughness and abnormal color areas of the sea surface as desired. and area estimation device and method. Background technique [0002] Red tides, oil spills, fronts, underwater reefs and other marine phenomena and processes that widely exist on the sea surface can appear as abnormal areas of roughness and color on the sea surface. In the existing ocean observation methods, it is difficult to determine the exact position and range through visual, photographic and video observation methods, and there are defects such as poor maneuverability and low accuracy through satellite or aerial remote sensing methods. How to obtain information such as the exact location and range of the above-ment...
