Real-time virtual ship video displaying method for AIS data

Abstract

The invention discloses a virtual ship real-time video displaying method for AIS data. The method includes the following steps that step1, a GPS is used for accurately positioning the ship displaying area of an electronic navigation channel chart and making the ship displaying area be in accordance with a video monitoring area; step2, the displaying ratio of the simulated ship size to the relative position size between simulated ships is adjusted in the electronic navigation channel chart, so that the displaying ratio of the simulated ship is in accordance with that of ships in video monitoring; step3, based on parameters which are received at this time and provided by an AIS signal, navigation tracks of the ships are predicated before a next AIS signal is received and displayed in the electronic navigation chart in a simulated mode, so that the positions of the simulated ships displayed in the electronic navigation channel chart are in accordance with the actual positions of the ships in video monitoring. Virtual ship video displaying is performed on the AIS data, the positions of the virtual ships are predicated, and the displayed AIS virtual ships accurately correspond to ship images in video monitoring.

Description

technical field [0001] The invention relates to a method, in particular to a video display method of a real-time AIS data virtual ship. Background technique [0002] At present, with the rapid development of the shipping industry in recent years and the increasingly busy water traffic, it is particularly important to ensure the safety of water traffic, which is directly related to social stability and the safety of people's lives and property. With the advancement of science and technology, various ship safety supervision technologies are constantly updated and developed. At present, water traffic management departments widely use ship monitoring methods, including AIS ship automatic identification system, video monitoring system, etc. [0003] AIS Ship Automatic Identification System (Automatic Identification System) is composed of shore-based base station equipment and ship-borne equipment. It is a digital navigation aid system integrating network technology, modern commu...

Problems solved by technology

[0005] Both the AIS system and the video surveillance system have unique monitoring effects in the monitoring of ships in inland waterways, and the two complement each other. Through the video surveillance system, we often only know that there is a ship at a certain location, but do not know other information about the ship; and The information displayed on the ship in the electronic channel chart is relatively rich, but it is impossible to understand the real image of the ship and the intuitive navigation status

During use, the user usually needs to use these two systems to simultaneously grasp the navigation data and real-time dynamics of a certain ship. At this time, it is necessary to accurately find the ship in the two systems. Because the technical principles of the two systems are different, The monitoring screens presented are quite different, and it is often impossible to accurately correspond to the ships in the monitoring screens of the two systems, which causes inconvenience in use
