Problems solved by technology

At present, the method of manually controlling the camera pan/tilt can generally be used to track the ship to be detected. This method requires the attention of the on-duty personnel, especially the ability to respond to abnormal situations. caused by inattention
In addition, the video image motion detection and tracking method can be used. This method will be affected by various scene lights and weather, and the processing algorithm after image acquisition is complex and has a large processing delay. It is difficult to meet the requirements of real-time tracking

Embodiment Construction

[0048] Such as figure 1 , the ship real-time tracking system of the present invention such as figure 2 As shown, the system includes an AIS message collection module 201 , an information processing module 202 , a PTZ camera 203 and a monitoring center 204 . Wherein the AIS message collection module 201 mainly collects the AIS information of the ship and stores it in the AIS database, and transmits the information of the relevant ship coordinates, speed and focus of the collection to the information processing module; the information processing module 202 is composed of the AIS information processing module and The dynamic prediction module is composed of the AIS information processing module, which mainly transforms the AIS information of the target ship's coordinates, speed and focal length with time. Predictive calculation of speed and focal length, and select and control the PTZ camera according to the result of dynamic predictive calculation. In order to adapt to a larg...

Abstract

The invention relates to a ship real-time tracking monitoring method. The method comprises the steps that a ship automatic identification unit collects an AIS message and related information transmitted by a tracked ship and stores the collected information in an AIS database of a ship tracking system; any one ship is selected to be monitored, the latest ship position and speed information recorded in the database acts as an initial monitoring value, and coordinate position transformation, speed transformation and focal length conversion are performed on AIS information of a target ship required to be tracked according to the initial monitoring value so that related transformation values are obtained; navigation coordinates and ship speed of the ship of the next moment are predicted according to the transformation values, and control threshold examination is performed on the prediction values so that a tracking holder camera is confirmed; and control parameters of the tracking holder camera are corrected. The ship real-time tracking monitoring method has advantages being low in signal processing complexity and high in accuracy so that working efficiency of on-duty personnel can be greatly enhanced.

Description

technical field [0001] The invention relates to a tracking and monitoring method, in particular to a ship real-time tracking and monitoring method using a pan-tilt camera using AIS information. Background technique [0002] In order to ensure the safe passage of ships in the waterway, it is necessary to track and monitor the ships in the water area to actively avoid safety accidents. At present, the method of manually controlling the camera pan / tilt can generally be used to track the ship to be detected. This method requires the attention of the on-duty personnel, especially the ability to respond to abnormal situations. caused by inattention. In addition, video image motion detection and tracking methods can be used. This method will be affected by various scene lights and weather, and the processing algorithm complexity after image acquisition is high, and the processing delay is large. It is difficult to meet the requirements of real-time tracking control. In addition t...
