Embodiment Construction

[0021] like figure 1 , 2 As shown, a ship-borne photoelectric auxiliary system for safe navigation includes a video acquisition unit 10 , a control host 20 , a display device 30 , and control buttons 40 . The video acquisition unit 10 includes a first thermal imaging lens 110 , a second thermal imaging lens 120 , a third thermal imaging lens 130 , and an ultra-low illumination lens 140 . The thermal imaging lens 1 110 has a focal length of 25 mm, the thermal imaging lens 2 120 and thermal imaging lens 3 130 have a focal length of 12.3 mm, and the ultra-low illumination lens 140 has a focal length of 8 mm.

[0022] The video acquisition unit 10 of the present invention adopts a thermal imaging lens and an ultra-low-illuminance lens to be used alternately. In daytime and when the visibility is low, the ultra-low-illuminance camera can be used to observe the navigation situation and navigation indicator lights ahead; In weather such as weather, rain, snow, etc., the thermal ima...

Abstract

The invention relates to a shipborne safety navigation electro-optical aided system. The shipborne safety navigation electro-optical aided system comprises a video acquisition unit, a control host, a display device and a control key; the video acquisition unit comprises a thermal imaging lens I, a thermal imaging lens II, a thermal imaging lens III and a super low illumination lens; the focal length of the thermal imaging lens II is the same as that of the thermal imaging lens III; the control host comprises a DSP (Digital Signal Processor) processing board and a video selection module; and the DSP processing board comprises an image pretreatment module, an image mosaicking module and an image fusion module. According to the shipborne safety navigation electro-optical aided system provided by the invention, the finally formed video image is wide in range and large in depth of field, so that a scene observed by the shipborne safety navigation electro-optical aided system is larger and the definition is higher, thus the shipborne safety navigation electro-optical aided system can be widely installed and used in various ships.

Description

technical field [0001] The invention relates to the technical field of marine equipment, in particular to a ship-borne photoelectric auxiliary system for safe navigation. Background technique [0002] With the continuous advancement of science and technology, the shipping industry has changed fundamentally, but accidents at sea still occur frequently, and the harm caused by these accidents is huge. Major marine accidents may not only cause huge economic losses to shipping companies, but may also cause casualties and environmental pollution, so safe navigation of ships is very important. [0003] In order to improve the safety of ship navigation, people have installed various photoelectric auxiliary systems on board. For example, Chinese patent 200920228149.X discloses an all-weather high-speed marine night vision device, which uses a CCD camera and an infrared thermal imager to take pictures alternately, and can discover, identify and confirm targets around the clock, ensur...
