Under picture, image co-registrations are carried out to two pictures by processor 50 later and obtain clearly picture；This first pair optical filtering at this time
The first camera lens of optical filter face 10 of piece switch switching cut-off infrared light works, second pair of optical-filter switcher switching
The second camera lens of optical filter face 30 of cut-off visible light works；First camera lens 10 is focused at visible wavelengths, quilt
The light that first pair of optical-filter switcher filters off infrared light enters first sensor 20, thus the clearly visible light picture that obtains focusing
Face, since illumination is faint, which only has recorded the colour information of part；Second camera lens 30 under IR wavelength into
Row focusing enters second sensor 40 by the light that second pair of optical-filter switcher filters off visible light, so that it is clear to obtain focusing
Infrared light picture；The infrared light picture has recorded black and white profile information；First sensor 20 respectively will with second sensor 40
Visible light picture and infrared light picture are sent to processor 50, and processor 50 is by Image Fusion, by the visible light picture
It is merged with the infrared light picture, to obtain clearly shooting picture under conditions of night low illuminance.
It is above-mentioned by taking the street of day and night change as an example, to the workflow of the binocular camera for carrying double optical-filter switchers into
Introduction is gone, it should be noted that above-mentioned driving mechanism 120 can be divided into stepper motor driving according to the difference of driving principle
Four kinds of mechanism, magnetic valve driving mechanism, gear driven mechanism and pulley driving mechanism situations, above-mentioned four kinds of driving situations are applicable in
In different shooting environmentals, next coming in order are illustrated.
(1) stepper motor driving mechanism.
Referring to Figure 12, stepper motor driving mechanism includes stepper motor 121, the power output shaft of the stepper motor 121
121A is connect with composite filter mating plate 110, and when stepper motor work, stepper motor drives the power output shaft to provide displacement of the lines,
To drive an optical filter in composite filter mating plate 110 to move to position corresponding to camera lens, stepper motor driving mechanism work
Work is stablized, and driving speed can be adjusted with the difference of stepper motor model, can be suitable for different operative scenarios.
(2), magnetic valve driving mechanism.
Referring to Figure 13, magnetic valve driving mechanism includes the electromagnet 122 of a pair of opposing, and is arranged in composite filter
The metalwork 123 that can be adsorbed by the electromagnet 122 on piece 110, the metalwork 123 are located at two electromagnet being oppositely arranged
Between 122；When specific works, the electromagnet 122 of this side, which is powered, generates magnetic force, and the power-off of opposite side electromagnet 122 is without magnetic force, at this time originally
Side electromagnet 122 adsorbs the metalwork 123 and moves to this side, so that composite filter mating plate 110 be driven to move to this side；On the contrary, right
Side electromagnet 122, which is powered, generates magnetic force, and the power-off of this side electromagnet 122 is without magnetic force, and opposite side electromagnet 122 adsorbs the metalwork at this time
123 to allocinesi, to drive composite filter mating plate 110 to allocinesi.Pass through one group of electromagnet 122 from two being oppositely arranged
The metalwork 123 is adsorbed in side, and the optical filter of different cutoff wavelengths in composite filter mating plate 110 is driven to move to position corresponding to camera lens
It sets.Magnetic valve driving mechanism has faster driving speed, changes unexpected shooting environmental for light and shade condition, can cut in time
Optical filter is changed, there is stronger mobility.
(3), gear driven mechanism.
Referring to Figure 14, gear driven mechanism is used on 124 output shaft of the first motor including the first motor 124, setting
The gear 125 of transmission, and the rack gear 125A being engaged on composite filter mating plate 110 with 125 phase of gear is set；Specific works
When, the work of the first motor 124 drives the gear 125 to rotate by output shaft, and gear 125 in the course of rotation, passes through rack gear
125A drives composite filter mating plate 110 to move, and when the first motor 124 rotates forward, composite filter mating plate 110 is moved to side, when first
When motor 124 inverts, composite filter mating plate 110 is moved to the other side, to drive in composite filter mating plate 110 in this way
One optical filter moves to position corresponding to camera lens.Gear driven mechanism movement is more steady, can reduce switching optical filter
Mechanical oscillation in the process are conducive to protect equipment.
(4), pulley driving mechanism.
Referring to Figure 15, pulley driving mechanism includes the second motor 126, the first belt pulley 127, the second belt pulley 128 and
Belt 129, wherein first belt pulley 127 is arranged on the output shaft of the second motor 126, first belt pulley 127 and this
Two belt pulleys 128 are connected by belt 129, which is connect with composite filter mating plate 110 by connector 129A, the connection
Part is a cylinder, and one end of the cylinder connect with belt 129, and the other end is connect with composite filter mating plate 110, when specific works, the
Two motor 126 rotates forward, and 127 drive belt 129 of the first belt pulley is moved to side, to drive composite filter by connector 129A
Mating plate 110 is moved to side, and similarly, when the second motor 126 inverts, composite filter mating plate 110 is moved to the other side, to pass through this
Kind mode drives an optical filter in composite filter mating plate 110 to move to position corresponding to camera lens.The mode of belt wheel drive
It can be effectively protected composite filter mating plate 110, driving mechanism drives cause to filter by force when composite filter mating plate 110 being prevented to be stuck
Piece fragmentation.
It should be noted that in low illuminance, above-mentioned second mesh when shooting infrared light picture, due to light compared with
Weak, the light intensity of infrared light is also inadequate, affects the clarity of infrared light image, in this regard, being arranged on the second mesh useful
