Description
Technical Field

Background
With the development of social economy, the transportation volume of personnel and materials continuously rises, and the transportation channel covers three-dimensional transportation links such as land transportation, water transportation and air transportation, wherein the water transportation is the first choice for the transportation of materials with insensitive transportation time efficiency and large density due to the advantage of low unit cost, for example, the south transportation in the north coal south transportation is the sea transportation. Besides the ocean, the water transportation channel also comprises an inland river water system, in particular to a great river such as the Yangtze river. However, shallow spots and reefs possibly existing below the water surface of the local part of the river, the lake and the sea are larger and larger, and the tonnage and the draft of the transport ship are larger and larger, so that the ship can not navigate at will, but must travel along a navigation channel mapped by a shipping administration department, and the situation that the ship touches the bottom and runs shallow, even drifts to cause collision with piers and other shipping facilities and the like is avoided. In order to guide a passing ship to run along a channel, except for the fact that the ship can be provided with a corresponding positioning system, a navigation mark is generally arranged on the side edge of the channel, the navigation mark is indicated to the passing ship through a mark body reflecting the ship and ambient light lamplight or an additionally arranged flash lamp, and the like, the ship is guided to run according to a specified channel like a cone barrel guiding vehicle running on an isolation control road, so that the navigation safety of the ship and the safety of lives and properties of passengers are guaranteed. Certainly, the ship buoy is also similar to a cone barrel for isolation on a control road and sometimes damaged by a vehicle, and the navigation buoy is sometimes damaged by the impact of a ship deviating from a channel, so that the safe navigation of the subsequent passing ship is seriously threatened, the reef is touched to be stranded if the ship buoy is light, and the heavy person or even the ship can be damaged and die. Besides possible reasons of insufficient driving skills and rapid water flow of the ship rudder, the reason that the traditional navigation mark body passively reflects light and the low-power navigation mark lamp flashes at a fixed frequency cannot bring sufficient attention to the rudder is also a big reason.
Therefore, aiming at sailing ships, how to effectively avoid collision with peripheral ships, navigation marks and submerged reefs becomes a big research problem in the industry, if an effective scheme does not exist in the prior technical scheme, a camera is adopted for monitoring and needs to be maintained, and if the camera is not maintained in time, the detection is easy to be inaccurate; in addition, the camera is greatly influenced by the environment in the foggy weather, so that peripheral obstacles cannot be effectively observed.
