Description

Technical Field

[0001] This utility model relates to the field of ship video tracking and positioning technology, specifically a video tracking and positioning device for ship navigation. Background Technology

[0002] Video tracking and positioning devices for ship navigation are equipment that combine video acquisition, intelligent analysis and positioning technologies. They are mainly used to monitor the ship's surrounding environment in real time, track targets (such as other ships, obstacles, coastlines, etc.), and combine positioning information to assist in navigation safety and management.

[0003] Its working principle is to use multiple monitoring cameras on board the ship to collect video footage in real time of key areas such as the surrounding sea area, deck, and bridge, covering blind spots or key monitoring scenarios. With the help of computer vision algorithms (such as motion detection, target recognition, and trajectory prediction), it automatically identifies targets in the video (such as ships, buoys, islands, fishing nets, etc.) and tracks their movement trajectory in real time. When a target enters a dangerous area or there is a risk of collision, it issues an early warning. Combining the ship's GPS, electronic chart (ECDIS), and radar equipment data, it fuses and analyzes the position of the tracked target in the video with the ship's own position and navigation route, and intuitively displays the target's relative position, distance, and heading on the screen to assist the driver in decision-making.

[0004] Surveillance cameras act as the "eyes" of a vessel, transmitting video footage in real time. However, these cameras are typically mounted on the exterior of the ship, making them susceptible to splashing water and water droplets or mist onto the lenses, which can interfere with the monitoring. Therefore, a video tracking and positioning device for ship navigation is proposed. Utility Model Content

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0021] This utility model provides a technical solution: such as Figures 1 to 4 As shown in this embodiment, a video tracking and positioning device for ship navigation includes a monitoring camera 1. A mounting base 2 is fixedly installed at the bottom of the monitoring camera 1. A transparent protective cover 4 is provided above the monitoring camera 1. The transparent protective cover 4 has a hemispherical structure. A connecting seat 5 is fixedly connected to the bottom of the transparent protective cover 4. The connecting seat 5 has an annular structure. A connecting plate 6 is fixedly installed at the bottom of the connecting seat 5. The connecting plate 6 has an annular plate. A connecting groove 8 is provided at the upper edge of the mounting base 2. The connecting groove 8 and the connecting plate 6 are mutually adapted. An external thread is provided on the outer ring sidewall of the connecting plate 6. An internal thread is provided on the outer ring inner wall of the connecting groove 8, which is threadedly engaged with the external thread.

[0022] Among them, a sealing groove 9 is also provided at the upper edge of the mounting base 2. The sealing groove 9 is located outside the connecting groove 8. The depth of the sealing groove 9 is less than the depth of the connecting groove 8. A sealing ring 7 is provided inside the sealing groove 9.

[0023] The outer diameter of the connecting seat 5 is larger than the outer diameter of the connecting plate 6, the inner diameter of the connecting seat 5 is equal to the inner diameter of the connecting plate 6, and the connecting seat 5 and the sealing groove 9 are mutually compatible.

[0024] With this configuration, when the connecting plate 6 is threaded into the connecting groove 8, the edge of the connecting seat 5 extending out of the connecting plate 6 will enter the sealing groove 9, thereby compacting the sealing ring 7 in the sealing groove 9, thus ensuring the sealing of the connection between the transparent protective cover 4 and the mounting seat 2, and preventing water from seeping into the interior of the transparent protective cover 4.

[0025] The mounting base 2 has four fixing plates 3 fixedly connected to its bottom edge. The four fixing plates 3 are arranged in a ring array and have fixing holes.

[0026] The surveillance camera 1 can be fixed to the installation location on the ship by using the external fixing bolts and fixing plate 3.

[0027] The outer wall of the transparent protective cover 4 is coated with a nano-silica film. With this design, when water falls onto the transparent protective cover 4, the "lotus effect" prevents the water droplets from adhering to the lens surface. Instead, the water droplets quickly shrink into spherical shapes and slide off, reducing the formation of a water film and ensuring that the monitoring camera 1 can capture clear images.

[0028] This utility model provides a video tracking and positioning device for ship navigation, the specific working principle of which is as follows:

[0029] Multiple surveillance cameras 1 (electrically connected to a computer) onboard the ship collect real-time video footage of key areas such as the surrounding sea area, deck, and bridge, covering blind spots or key monitoring scenarios. Using computer vision algorithms (such as motion detection, target recognition, and trajectory prediction), targets in the video (such as ships, buoys, islands, and fishing nets) are automatically identified and their movements are tracked in real time. Warnings are issued when a target enters a dangerous area or poses a collision risk. Combining data from the ship's GPS, electronic charts (ECDIS), and radar equipment, the positions of the tracked targets in the video are fused and analyzed with the ship's own position and navigation route, displaying the target's relative position, distance, and heading on the screen to assist the navigator's decision-making.

[0030] The surveillance camera 1 is protected by a transparent protective cover 4 to prevent water from directly interfering with it. The transparent protective cover 4 has a hemispherical structure, which ensures that water droplets falling on it can quickly slide off, preventing them from adhering to the cover. By coating the outer wall of the transparent protective cover 4 with a nano-silica film, when water falls on it, the "lotus effect" prevents the water droplets from adhering to the lens surface. Instead, the droplets quickly shrink into a spherical shape and slide off, reducing the formation of a water film and ensuring that the surveillance camera 1 can capture clear images.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
