Problems solved by technology

[0004] However, since the video information recorded by the AIS and the camera is independent, although the AIS information can be displayed on the electronic chart, it is not as intuitive as the video information after all; and the video information is intuitive but has a large amount of information. The manual workload is very large and complex

Embodiment Construction

[0032] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0033] Such as figure 1 As shown, the maritime intelligent monitoring method of the embodiment of the present invention mainly includes the following steps:

[0034] S1. Obtain the basic information of the target sent by the ship automatic identification system. The basic information of the target is: when the moving target enters the coverage area of ​​the AIS receiver, the AIS receiver receives the AIS information of the target and analyzes the result;

[0035] S2. According to the basic information of the target, estimate the time and place when the target reaches the video surveillance boundar...

Abstract

The invention discloses a special maritime camera and an intelligent maritime monitoring method. The special maritime camera comprises an information acquisition unit which is used for acquiring the basic information of a target from an automatic identification system (AIS) of a ship, an evaluation unit which is used for evaluating the time and the place when the target reaches a video monitoring boundary according to the basic information of the target and performing amendment periodically; a video data processing unit which is used for acquiring video data when the ship enters a video acquisition area according to the evaluated time and place and processing the video data by a significance detecting algorithm based on frequency modulation to obtain the information of the target, and a matching unit which is used for matching the information of the target with the information of the AIS, calibrating the target in the video and keeping tracing till the target leaves the monitoring area. According to the special maritime camera, the maritime information system of the AIS and the video information are organically integrated in the camera, so that the AIS information of a moving ship can be displayed in the video directly.

Description

technical field [0001] The invention relates to the field of intelligent monitoring, in particular to an AIS and CCTV-based maritime intelligent monitoring method and a special camera for maritime affairs. Background technique [0002] AIS (Automatic Identification System, Ship Automatic Identification System) is a new type of ship aid produced with the rapid development of computer and telecommunication technology following ARPA (Automatic Radar Plotter) and ECDIS (Electronic Chart Display and Information System). navigation equipment. It has the advantages of large amount of information, transmission over obstacles, strong anti-weather interference, and display of short-distance targets. It can be used in combination with electronic charts to display signs such as ship names, ship positions, headings, speeds, and headings on electronic charts. As an emerging science and technology, AIS has promoted the informatization and intelligent construction of maritime management, a...
