[0020] Figure 2 This is a system architecture diagram of the maritime video monitoring system of the present utility model. DETAILED DESCRIPTION

[0021] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of the present application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not used to limit the scope of the present invention.

[0022] Figure 1 This is a structural diagram of the utility model maritime video monitoring system and Figure 2 This is a system architecture diagram of the maritime video monitoring system of the utility model, including:

[0023] Fixed-focus gun camera 1 for collecting data on monitored waters;

[0024] Zoom ball camera 2 for collecting navigation marks and ship information in distant waters;

[0025] A data processor 5 for processing fixed-focus bolt camera information and zoom ball camera information;

[0026] A monitoring display 6 for displaying maritime data provided by the data processor;

[0027] The data processor 5 is connected in communication with the fixed-focus gun camera 1 and the zoom ball camera 2 , and the monitoring display 6 is connected in communication with the data processor 5 .

[0028] It can be understood that the utility model first uses a fixed-focus gun camera 1 to monitor the entire target water area, determines the monitoring range of the zoom ball camera 2 according to the monitoring scene, and monitors the long-distance target. The liquid level radar 3 obtains the camera installation height, and the data processor 5 converts the pixel coordinates of the object detected by the zoom ball camera 2 into a preset world coordinate system, and converts the world coordinates of the object into the coordinate system of the fixed-focus gun camera 1, obtains the pixel coordinates of the fixed-focus gun camera 1 of the object, associates the pixel coordinates of the variable and fixed-focus gun cameras, and displays them on the monitoring display 6. According to the prior art patent publication number: CN115830124A discloses a camera pixel coordinate and geodetic coordinate conversion method and system based on matching. First, determine the three-dimensional position of the target camera in the world coordinate system; then, based on the three-dimensional position, obtain the remote sensing image of the target camera's camera coverage range and the video image taken by the target camera; finally, match the remote sensing image and the video image and input them into the preset coordinate linear transformation image matching model to obtain the geodetic coordinates corresponding to the pixel coordinates in the video image. Therefore, the prior art provides certain technical inspiration for the pixel coordinate association method of the variable-focus and fixed-focus gun cameras involved in the present invention.

[0029] It can be further understood that the utility model cannot determine whether a ship will collide with a navigation mark or a bridge, which is mainly achieved through the following steps:

The pixel area of ​​the navigation mark is determined according to the pixel coordinates of the navigation mark, and the world coordinates of the bridge pier are determined according to the installation position of the camera. After the coordinate conversion, the pixel area of ​​the bridge pier is obtained. Based on the data processor 5, it is determined whether the ship will enter the pixel area of ​​the navigation mark or bridge pier. If it enters, it is considered that the ship and the navigation mark or bridge are in danger of collision, and the sound and light alarm device 4 issues a warning to it, and the ship is highlighted in the monitoring display 6. Specifically, Figure 2 shown.

[0031] It should be noted that the utility model can perform ship superelevation monitoring, which is mainly achieved through the following steps:

[0032] First, the ship is detected by a variable and fixed focus gun, and the data processor 5 generates a ship detection frame, and the height of the ship detection frame, that is, the height of the ship above the water surface, is obtained. Then, the liquid level radar 3 installed on the bridge obtains the bridge clearance height. If the height of the ship above the water surface is greater than the bridge clearance height, it is considered that the ship is too high, and the sound and light alarm device 4 issues a warning to it, and it is highlighted on the monitoring display 6 interface.

[0033] In some embodiments of the present invention, the system further includes: a liquid level radar 3 for collecting bridge height signals, and the liquid level radar 3 is communicatively connected with the data processor 5 .
