Problems solved by technology

[0009] In order to solve the above-mentioned problems existing in the prior art, the present invention will design a kind of panoramic color video that can enable the ship to get the panoramic color video of the port shore at night and in foggy days, so that the ship can still pass normally at night when the visibility is low. Navigation system and construction method for ships entering and leaving port under foggy conditions

Embodiment Construction

[0062] Below in conjunction with accompanying drawing, the present invention is further described:

[0063] like Figure 8 As shown, a navigation system for ships entering and leaving the port under night fog conditions, including a coast panorama system around the port 1, a color video reconstruction system 2 under night fog conditions, a wireless request signal sending module 3, and a wireless video signal sending module Module 4, wireless video signal receiving module 5, infrared camera imaging system 6, video display module 7 and differential GPS system 8;

[0064] The coast panorama system 1 around the port is installed in the computer of the control center on the shore, and is used to store the coast panorama around the port obtained by taking pictures of the coast 10 around the port under good visibility conditions and the pictures corresponding to each picture. Photograph position and infrared camera 14 parameter information; Under the described night fog condition, co...

Abstract

The invention discloses a navigation system for entering and leaving port of ships and warships under a night-fog weather situation and a construction method thereof, the navigation system includes a port-circumference seacoast panorama system, a color video reconstruction system for the night-fog weather situation, a wireless request signal sending module, a wireless video signal sending module, a wireless video signal receiving module, an infrared camera imaging system, a video display module and a differential global position system (GPS)system; and the construction method comprises the construction of the port-circumference seacoast panorama system and the construction of the color video reconstruction system for the night-fog weather situation. According to the navigation system and the construction method thereof, port-circumference seacoast panoramas are stored in advance in the ships and warships frequently haunting about a port, so that the ships and warships can still clearly know the details circumstances of a port seacoast without need of commands from an on-shore control center, and the ships and warships can enter and leave the port at a day with night fog. Through use of the navigation system and the construction method thereof, differential GPS information of the ships and warships can be effectively utilized to precisely locate direction, speed, location and other information of the ships and warships, and maps with best view-field effects can be sent to the ships and warships.

Description

technical field [0001] The invention relates to the technology of navigation of ships entering port, monitoring of targets on water and monitoring of objects on shore, in particular a navigation system for entering and leaving port of ships under night fog conditions and a construction method thereof. Background technique [0002] When a ship enters or leaves the port in dense fog or at night, due to low visibility, the navigation aids cannot be seen clearly, and the radar will also cause inaccurate ranging due to the influence of dense fog, and the ship requires an accurate route when entering and leaving the port. At this time, relying only on radar and electronic charts, there is no obvious object mark for visual positioning, it is difficult to find the correct route, and there is a great potential safety hazard. According to incomplete statistics from the shipping department, the collision accidents of ships in poor visibility have exceeded one-third of all collision acc...
