Problems solved by technology

[0004] The technical problem solved by the present invention is that, since the existing technology can only function when the visibility is high during the day, at night or under conditions of heavy fog, the existing monitoring is almost useless, and the existing monitoring system must be manually Only by controlling the console and the zoom lens can the ship be monitored in real time, which leads to the need to use a lot of manpower to solve the above problems and at the same time cannot guarantee the work efficiency, which increases the difficulty of monitoring to a certain extent, thus providing a Optimized Ship Monitoring Method

Embodiment Construction

[0036] 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.

[0037] Such as figure 1 , 2 As shown, the present invention relates to a ship monitoring method, the monitoring method includes a target recognition method and a target tracking method, and the target recognition method includes the following steps:

[0038] Step 1: Obtain a panoramic video, initialize the background image, and set it as a grayscale image;

[0039] Step 2: Capture the video image in real time, set it as a grayscale image, perform a difference operation with the background image, compare the difference, and record the difference as M;

[0040] Step 3: Binarize the differential image of the video image and the background image, compare M with the threshold T, if M is greater than the threshold T, set the gray value of the differential image to 255, otherwise set its gray value to 0,...

Abstract

The invention relates to a ship monitoring method. The monitoring method comprises a target identification method and a target tracking method, wherein in the target identification method, after an intercepted real-time video image and a background image are subjected to differential operation and binarization, a ship target is obtained by using a region growing algorithm, and the identified ship target is tracked and locked. By matching the target identification method, the target tracking method, a target locking method and a pairing comparison and database management method, a monitoring system can capture a ship and acquire continuous ship video under the condition of fog or night so as to realize all-weather monitoring of a shipping lane, ensure smoothness of the shipping lane and safety of the ship, reduce manual operation and realize automatic management; and the data information and the like acquired by monitoring are stored into a database, so that the data information and the like are convenient for digital management of the ship, can be timely called as required and can assist managers in learning more information about the ship.

Description

technical field [0001] The invention belongs to the technical field of electric communication technology; test circuit or test equipment; circuit or equipment for detecting, indicating, or reporting faults or accidents, and in particular relates to a ship monitoring method which can be realized by computer programming. Background technique [0002] With the rapid development of the electronics industry, the update of electronic technology continues to accelerate. Various sensors, cameras and collectors are widely used in the research and development and use of electronic technology, and due to the increasing requirements of various industries for equipment automation and functional digitization, sensors The number of electronic devices such as cameras and collectors continues to increase, and their functions are continuously enhanced. [0003] With the continuous development of the monitoring system, the video monitoring system has been rapidly upgraded from manual control t...
