Between daytime imaging system by between daytime between varifocal imaging device 11, daytime ccd video camera 10 form, imaging system is installed son round the clock on the switching platform 6 between whole daytime, between daytime varifocal imaging device 11 become real image and ccd video camera 10 imaging target surfaces coupling between daytime, image in ccd video camera 10 target surfaces between daytime.
Laser illuminator system is made up of 4 laser projecting apparatus 1, is distributed in around the reflective mirror 2.Here the angle of divergence of laser projecting apparatus is identical with the reflective mirror visual angle, when 4 laser projecting apparatus 1 of laser illumination system are arranged, by orientation, the attitude of regulating 4 laser projecting apparatus, the hot spot of its ejaculation is overlapped fully at effective observed range place, the center of its coincidence is concentric with reflective mirror 2 optical axises.Thereby accomplish the visual field after hot spot under the situation of not regulating laser covers any zoom of imaging system substantially, cover whole visual field at big coverage place again.
It is relevant with image intensifier 15 input optical wavelength response condition that laser projecting apparatus optical maser wavelength is selected, and should select the optical maser wavelength projector of the higher near-infrared wavelength of image intensifier 15 quantum efficiencies, as the laser projecting apparatus of wavelength 808nm, 850nm.The laser projecting apparatus power selection is about 20W, if monitor area does not have personal safety requirements and can select than the high power laser projector.
In manufacturing process, varifocal imaging device 11 zoom signal line parallels between night varifocal imaging device 16 and daytime are realized zoom simultaneously, so that keep the homogeneity of visual field when changing round the clock.
In the hardware manufacturing process, varifocal imaging device 11 and optical imaging system should adopt ripe zoom lens between night varifocal imaging device 16 and daytime, with the reliability of strengthening system, can reduce cost simultaneously, shorten the processing duration.Must guarantee effective coupling of each optical interface when selecting camera lens, make optical energy loss be reduced to minimum.
Optical lens, the eyeglass of the eyeglass of selecting in the hardware manufacturing process, making can accept 360nm to 940nm wavelength with interior from the light wave of visible light until near infrared band, thereby obtain than the more light wave of visible light, simultaneously also and the light-wave band that can respond of image intensifier 15, night ccd video camera 13, ccd video camera 10 responses between daytime be complementary.
The CCD camera is selected the industrial monitoring camera of low-light (level) as far as possible round the clock, and ccd video camera 10 can be selected color camera between daytime, and night, ccd video camera 13 was because the achromatization image of collection image intensifier 15 should be selected B.
Control section comprise control to The Cloud Terrace, to night varifocal imaging device 16, between daytime varifocal imaging device 11 control and to Stepping Motor Control in the switched system round the clock, computer control is all adopted in the control of this instrument, its implementation method is connected to decoder for the control line of each controlled device, decoder and computer communicate by the RS-485 serial mode, send instruction to controlled device.
Because this instrument uses out of doors, when structural design, to carry out rainproof, anti-hail design.To semiconductor refrigerating heating system and corresponding automatic temperature measurement start stop apparatus be set in the suitable position of instrument according to the working temperature of CCD camera, image intensifier simultaneously.
Software systems comprise following content:
Obtain the vision signal of ccd video camera 10 between daytime or ccd video camera 13 outputs at night, change into digital signal, be shown on the screen in real time, picking rate was 30 frame/seconds, but single frames collection and be stored as file on hard disk, also the speed that can gather is in real time recorded into consecutive image, is stored on the hard disk with document form.Above function realizes that by image video recording capture card is programmed the recording and storing of consecutive image is that image video recording capture card passes through the DMA passage to the hard-disc storage data.
Analysis image visual field illumination, according to ccd video camera 10 between the daytime that sets in advance or 13 pairs of illumination response condition of ccd video camera at night, carry out automatic or manual system's switching round the clock, when night ccd video camera 13 work, according to 13 pairs of visual fields of ccd video camera at night illumination response condition, automatic or manual starts laser illumination system.This place estimates by the average gray of computed image the evaluation of visual field illumination, and the performance of this grey scale and image intensifier, the illumination responding ability of CCD camera are relevant, need to measure by the sense organ of naked eyes, determine gray scale-illumination evaluation criterion.
Interim analyse atmos disturbance situation needs timing, carries out real-time atmospheric perturbation correction to obtaining image automatically.Adopt the atmospheric perturbation algorithm to estimate correction.In general, observe more than 5 kilometers target and will use the atmospheric perturbation correcting algorithm.
By driving varifocal imaging device 11 and night varifocal imaging device 16 between daytime, the transformation system focal length realizes amplifying, dwindling target or visual field.
By on the image that shows in real time, clicking moving target, drive The Cloud Terrace and rotate the man-machine real-time tracking target of finishing jointly of realization.This algorithm is a coordinate difference of calculating institute's click location image coordinate value and picture centre, again by calculating the value of feedback and the visual angle of zoom system, pancreatic system, obtain target apart from the distance of instrument and width, the length of visual field, can calculate the actual range of institute's click location tool picture centre like this, the ratio of directions X distance and target range is exactly that The Cloud Terrace is finished to follow the tracks of and horizontally rotated angle, and Y direction distance is exactly the vertical anglec of rotation that The Cloud Terrace is finished tracking with the ratio of target range.
The definition of Real time identification image, the definition of Real time identification image, by driving the focus control of reflective mirror 2 repeatedly, the continuous image definition before and after the focusing of reflective mirror 2 relatively obtains the distinct image in target visual field.This place mainly realizes the evaluation of definition by many focuses of image acutance algorithm, by with than each image of acquisition after the long focusing of reflective mirror 2 small steps, dividing 12 representative region (horizontal 4 zones on the image, vertical 3 zones), calculate each regional sharpness value, and according to the correlation analysis of each regional sharpness value, obtain the unique evaluation index of each image, this correlation analysis obtains by weighted average, in general, image middle part sharpness value minimum, acutance situation about increasing progressively to the periphery, image is the most clear, relatively the acutance index of one section focus area, the position of focal length due to image sharpness index minimum, this moment, image was the most clear at last.
