Abstract
A multiple visual spots active infrared night visual meter comprises at least two CCD cameras, at least one infrared light source and an electric power source, wherein the eyepieces of the CCD cameras are respectively positioned in parallel and distributed in the same direction, and the infrared light sources are respectively distributed around the camera eyepieces. When the CCD cameras are two, the eyepieces of the two CCD cameras are respectively main close shot eyepiece and aiding middle and far shot eyepiece. The utility model can work on the condition of total dart and high brightness, meanwhile can display multiple aspects object image, more particularly is beneficial for the tracking of a flexible object and the watching of a plurality of objects, which overcomes the deficits that a focus varying eyepiece can only watch one image at the same time and that the flexible objects are easy to get lost when being tracked.
Description
Technical field
The utility model relates to a kind of many viewpoints active infra-red night vision device.
Background technology
Existing night vision device adopts low-light enhancement techniques and far infrared imagery technology more.
As shown in Figure 1, with the low-light level night vision device of low-light enhancement techniques manufacturing be by optical lens 1 ', image intensifier tube 2 ', eyepiece 3 ' and power supply 4 ' composition.By the surplus light in moonlight, starlight or city, target image is carried out the light enhancing and reaches the night vision purpose during use.But under complete dark (as basement, tunnel etc.) high brightness (daytime, strong illumination etc.) condition, can't use.
With the thermal infrared imager that the far infrared imagery technology is made, form by far infrared camera lens, rpyroelectric infrared device and corresponding electronic circuit, the heat distribution intensity of detection of a target object self when using, machine is processed into the image demonstration as calculated.It can be worked under the condition of complete black and high brightness, is not target body image but its shows, but target heat distribution intensity.
The high sensitive ccd video camera that grew up in recent years also can carry out night observation by faint light, to the light activated ccd video camera of near infrared, utilizes the infrared lamp irradiation can obtain satisfied image at night.
Above-mentioned two kinds of night vision devices and ccd video camera are by an optical lens, a kind of visual field object observing, even adapted varifocal optical lens, at one time also can only be with a kind of visual field object observing, especially the time to Moving Target Tracking, very easily lose objects must be observed big visual field for keeping target just not lose, and can't see target detail clearly this moment again.
The utility model content
The purpose of this utility model is to provide a kind of many viewpoints active infra-red night vision device, utilize this night vision device under full dark and high brightness conditions, to work, show simultaneously and look many visual fields target body image, and help to the tracking of moving target with to multiobject observation.
A kind of many viewpoints active infra-red night vision device provided by the utility model, it is characterized in that: comprise at least two ccd video cameras, at least one infrared light supply and a power supply, wherein: the camera lens of described ccd video camera is parallel and equidirectional distribution respectively, infrared light supply be distributed in respectively the ccd video camera camera lens around, and the direction of illumination of light source is consistent with the ccd video camera lens direction, and power supply is to each ccd video camera and the power supply of each infrared light supply.
Above-mentioned many viewpoints active infra-red night vision device, when ccd video camera was two, the camera lens of these two ccd video cameras was respectively main close shot camera lens and the auxilliary medium long shot of looking looked.
Adopted above-mentioned technical solution, be many ccd video cameras to the near infrared sensitivity, be equipped with the optical lens of different visual fields (focal length), overcome the shortcoming of existing two kinds of night vision devices and single-lens ccd video camera, can under the condition of full dark and high brightness, work, can show simultaneously and look many visual fields target body image.Be particularly advantageous in to the tracking of moving target with to multiobject observation, overcome the drawback of easy lose objects when zoom lens can only be observed piece image and Moving Target Tracking at the same time.

Embodiment
As shown in Figures 2 and 3, a kind of many viewpoints active infra-red night vision device provided by the utility model, comprise two ccd video cameras connecting by support 5, two infrared light supplies 1 and a power supply 4, the camera lens of these two ccd video cameras is respectively main close shot camera lens 3 and the auxilliary medium long shot 2 of looking looked.The camera lens 2,3 of ccd video camera is parallel and equidirectional distribution respectively, infrared light supply 1 be distributed in respectively ccd video camera camera lens 2,3 around, and the direction of illumination of light source is consistent with the ccd video camera lens direction, and power supply 4 is to each ccd video camera 2,3 and 1 power supply of each infrared light supply.
Power supply is the 220V civil power to be transformed into DC12V25A (Switching Power Supply) use for video camera and infrared light supply.
Ccd video camera requires the infrared light sensitivity, can select for use model be PC-175IR or W4T-902H or other to infrared light activated machine, operating distance can reach 60M-300M.
The optical lens focal length can be as requested operating distance and decide, medium long shot can be selected f4-25mm for use, relative aperture 1: 1.4--1: 0.95, the close shot camera lens can be selected f50--120mm or 300MM for use, relative aperture 1: 1.1--1: then operating distance is big for 4 infrared percent of pass height, can select " Seiko " for use, " rise dragon ", " COMPUTAR ", " robust and sturdy reaching ", " CHIKON " waits import and homemade camera lens.
Infrared light supply can select for use LED as luminophor, or with the light source of Halogen lamp LED as the respective distance of luminophor.
According to the experimental prototype that the utility model principle is made, selecting model for use at the close shot ccd video camera is that PC-175IR adapted focal length is the main visor head of 120mm.It is that PC-175IR adapted focal length is the auxilliary visor head of 25mm that the distant view ccd video camera is selected model for use, and the adapted model is the efficient infrared light supply of HTS-HWY300, and the maximum viewing distance of its night vision can reach 320m (actual measurement).
Claims (2)
1. the night vision device of viewpoint active infra-red more than a kind, it is characterized in that: comprise at least two ccd video cameras, at least one infrared light supply and a power supply, wherein: the camera lens of described ccd video camera is parallel and equidirectional distribution respectively, infrared light supply be distributed in respectively the ccd video camera camera lens around, and the direction of illumination of light source is consistent with the ccd video camera lens direction, and power supply is to each ccd video camera and the power supply of each infrared light supply.
