Based on the watch-dog of binocular camera, comprise base, horizontally rotate support, back shaft, tilt mount, shell and protective cover, when after CCD camera collection to image, by control module processing image information, and then control micro electric machine makes zoom lens automatic focusing; According to the illuminance that illumination detection module detects, control driver module by control module and make laser infrared lamp module luminous, control optical-filter switcher and switch different filter, and reported to the police by control module when unusual checking module detects abnormal scene.
Two groups of CCD cameras are viewing lens L1 and phtographic lens L2 respectively, and both optical axises are parallel, the alignment surface of spacing to be b, P1P2 be camera lens.Identical with the angle of visual field of phtographic lens if find a view, then the yardstick AC that finds a view is equal with photography yardstick BD, but has dislocation, and namely the scene observed of viewing lens is different from the scene that phtographic lens photographs, and its value is parallax ε, when photographing to the thing of object distance l, image distance is l ', by similar triangles relation, there is ε/b=l '/l, again from geometric optics, 1/l+1/l '=1/f ', so there be ε=bf '/(1-f '), b and f ' is structural constant, therefore parallax ε changes with object distance l, ranging system adopts the operation principle of stereoscopic range finding, and form link gear with zoom lens, by reflective from scenery self of the control module Direct Analysis carrying out calculating, Phase Difference Principle is utilized automatically to select single to focus or kinetoplast prediction focusing, zoom lens automatic focusing is made by control module control micro electric machine.
When the focusing value contrast of adjacent image is less than certain thresholding, the state of object scene and optical lens is relatively stable, now control system is in fine motion scanning mode, controls to export to still have to make focus adjusting mechanism to the trend obtaining the motion of larger amount of focus image direction, but controlled quentity controlled variable is small.When the focusing value contrast of adjacent image is greater than certain thresholding, show that object scene there occurs change, or optical lens has carried out zoom, the operation such as to have turned to, then control system enters the quick focussing process of large step-length.
When illumination detection module detects that illumination is sufficient, by control module control optical-filter switcher switch to can filtering infrared ray and induction visible ray filter, otherwise, when the illumination detected is lower than certain value, the filter being coated with penetrating film will be switched to, and driving laser infrared lamp module is luminous, can round-the-clock remote real-time image acquisition information, and by information storage in a storage module.
When illuminance is very low, according to the distance of target, control module will control driver module drive far away, in, nearly different laser infrared lamp pearl is luminous, launch after the beam expanding lens in zoom lens expands, infrared ray enters CCD camera imaging after reflections off objects, and laser infrared lamp electro-optical efficiency, generally about 50 ~ 60%, is 2 ~ 3 times of LED infrared lamp, so caloric value is low, the life-span is long, object.
When unusual checking module detects abnormal behaviour, can rotate by control module analysis and Control driver module drive motors 1 is corresponding with motor 2, preferential tracking target direction, captured target video information, effectively improves fail safe; When for normal scene, control module controls motor 1 and motor 2 rotates by certain frequency, can gather image information on a large scale.
The beneficial effect that the utility model reaches:
1, laser infrared lamp is simple relative to common LED modulated structure, electro-optical efficiency is high, caloric value is low, irradiation distance is far away and the life-span is grown, can at irradiating object under such as adverse circumstances such as haze, rainy day and night, improve utilance and the fail safe of security device, low-carbon environment-friendly.
2, shell is fin-shaped cutting, and is attached with louvre, perfect heat-dissipating, makes internal components reduce failure rate, long service life.
3, standby battery in power supply paralysis situation, by battery management module identification abnormal power-down, and then can make storage battery power supply to system, reaches real-time monitoring effect.
