Problems solved by technology

[0004] The technical problem that the present invention solves is, because in the prior art, in the process of existing ship video monitoring, often function point all is to lock the real-time navigating map of a certain ship, compare whether the ship is installed with GPS system or whether it is opened or not. Difficult to judge, resulting in the need to use a lot of manpower to accurately monitor the ships and check whether the ships use or turn on the GPS system. It may also be necessary to find the ships in danger one by one. The work efficiency cannot be guaranteed, and the current requirements for ships The problem of real-time positioning requirements, and then provides an optimized ship GPS positioning verification method and ship GPS interactive system

Embodiment Construction

[0038] The present invention will be described in further detail below in conjunction with the examples, but the protection scope of the present invention is not limited thereto.

[0039] As shown in the figure, a GPS positioning verification method of a ship, the positioning verification method includes the following steps:

[0040] Step 1.1: Use the camera to obtain the panoramic video, take the average value set of each pixel point of all frame images of the panoramic video within the latest T time as the background image A, and set it as a grayscale image;

[0041] Step 1.2: Take the video image B at the current time point and set it as a grayscale image; perform a difference operation between the video image B and the background image A, compare the difference, and record the difference as M;

[0042] Step 1.3: Binarize the differential image C of the video image B and the background image A, and compare M with the threshold Q. If M is greater than the threshold Q, set th...

Abstract

The invention relates to a ship GPS positioning and checking method and a ship GPS interactive system. According to the method, difference operation is carried out on a clipped video image and a background image, binaryzation is carried out, and then a ship object is obtained by using a region growing algorithm; locking and GPS positioning and checking are carried out on the identified ship object. The interactive system comprises a ship positioning terminal in communication connection with a ship real time information database and a GPS positioning and checking terminal which is composed of a processing analysis module employing the method and a camera, a display module and a communication module connected with the processing analysis module. According to the invention, a continuous ship video can be obtained, all-weather monitoring of a navigation channel is realized, ships which are not equipped with or are equipped with but do not start GPS systems can be screened out by using GPS technology, real time position locking of the ships can be carried out, smooth traffic in the navigation channel and driving safety of the ships can be guaranteed, manual operation is reduced, automated management is realized, and digital management of ships and acquiring of ship information by management staff are facilitated.
