Description

[0001] The present invention relates to an infrared camera and an obstacle detection system for the same,

The present invention relates to an infrared camera and an obstacle detection system for a ship having the same. More particularly, the present invention relates to an infrared camera and an obstacle detection system using the narrow angle lens module and the narrow lens module, And an obstacle detection system for a ship having the infrared camera.

In order to support the safe operation of ships, the Electronic Chart Display and Information System (ECDIS), Automatic Identification System (AIS), Global Positioning System (GPS) ) And radar are used in various types of systems.

In general, the Electronic Navigational Chart (ENC) is used to digitize the paper charts and use them as digital charts for electronic navigation equipment used in various ships to protect marine safety and marine environment. By using such electronic charts, the position, speed, direction, direction, and position of other vessels are displayed on the computer screen. In case of approaching dangerous objects or collision situations with other vessels, By preventing accidents, navigators can navigate vessels more safely than when using paper charts.

By increasing the level of safety navigation by the appearance of electronic charts, it is possible to protect valuable people and property in the sea, to prevent pollution, to protect the environment, and to carry out more smoothly and efficiently through efficient navigation management It was possible.

However, most of ship accidents are mostly collision between vessels, collision caused by collision between ships and fixed obstacles formed in coastal waters, forbidden waters, and coastal waters, etc. Recently, ship size has increased and ship types have diversified As a result, there have been major damages such as casualties caused by collision with ships, secondary damage such as property damage and marine pollution.

Since ship collision occurs mainly in ports near coastal areas and coastal areas, it is becoming more and more necessary to provide navigation information for ships and fixed obstacles in such areas to ships in operation more efficiently .

In addition, since most of the ship collisions occur in small ships of less than 100 tons in the coast near the land, or in most small ships such as fishing boats and small yachts, There are problems such as introduction cost, problem of equipment operation, lack of equipment installation space, and the like.
