Video-based three-dimensional virtual ship positioning and track simulation method

Abstract

The invention discloses a video-based three-dimensional virtual ship positioning and track simulation method which is characterized by comprising the following steps: 1, recognizing a ship on the basis of a video and extracting the characteristic information of the ship; 2, obtaining the position information and the motion direction of the ship in the video according to fixed time intervals; 3, realizing accurate positioning of a virtual ship in a three-dimensional virtual scene according to the obtained position information; and 4, fitting the obtained position with the current position point so as to generate the motion track of the ship in real time. According to the method, the real-time matching of ships in virtual scenes can be realized, the virtual dynamic representation of water transportation videos can be realized, and significance is brought to the management of ship navigation channels and the safe position prediction of ships.

There are many methods of 3D modeling technology. Image-based modeling technology is currently the most widely used method. Using the information of multiple images not only reduces the difficulty of feature matching, but also improves the accuracy of reconstruction. There are many traditional water transport 3D systems, but they cannot It matches the real water transportation scene information and cannot meet the real-time requirements, so real-time demonstration and real dynamic presentation cannot be achieved
