Abstract
The utility model relates to a vehicle night vision camera. The vehicle night vision camera is applied to car backing safety assistance, and comprises a housing, a lens, an optical filter switcher, and a main control circuit board, the periphery of the lens is provided with infrared lamps, the optical filter switcher is disposed behind the lens, and the infrared lamps, the optical filter switcher, and the control circuit board are electrically connected. The vehicle night vision camera is advantageous in that, images are clear in daytime car backing, infrared ray assistance is provided in night car backing, scenes behind a vehicle can be clearly seen, and car backing safety is improved.
Description
Technical field
The utility model relates to a kind of camera, relates in particular to a kind of on-vehicle night vision camera.
Background technology
Along with improving constantly of people's quality of life, automobile generally enters our routine work life, and the safety problem in vehicle traveling process also more and more causes people's attention simultaneously.Very dark when especially move backward night, be beyond recognition reversing rear scenery.Easily there is the formal matter part of thrusting into of moveing backward, bring immeasurable consequence, Given this in the urgent need to a reverse image both daytime, see that see night again, reduce the generation of traffic accident.
At present, on market, existing camera can only can be seen below image clearly daytime, to night very dark, be beyond recognition the situation after car, so need also can see the camera of clear reverse image a night.
Utility model content
The problems referred to above that exist for solving prior art, the utility model proposes a kind of on-vehicle night vision camera, are applied to reversing safety auxiliary, daytime, reverse image was clear, when move backward night, there is infrared ray auxiliary, also can clearly see the scenery at car rear, improved the fail safe of reversing.
The utility model can be solved by the following technical programs:
A kind of on-vehicle night vision camera, comprise housing, camera lens, optical-filter switcher, master control circuit board, the surrounding of described camera lens is provided with infrared lamp, camera lens be below provided with optical-filter switcher, infrared lamp, optical-filter switcher are electrically connected to control circuit board.
As preferred embodiment:
Described master control circuit board includes illuminant module, pattern process module and video output display module.
Described optical-filter switcher includes two filters, is respectively 650nm colored filter and 850nm infrared filter, is respectively used to pass through at filtering on daytime infrared ray and night infrared ray.
Described optical-filter switcher includes transfer strip switch, and transfer strip switch is connected on plates lamp for vehicles both positive and negative polarity, opens license plate lamp, utilizes night license plate lamp as power supply, completes the switching of two filters after illuminant module induction.
Described optical-filter switcher can also comprise photo resistance and drive circuit, and this drive circuit and described master control circuit board are electrically connected, and automatically responds to and switches two filters.
By above technical scheme, a kind of on-vehicle night vision camera the utility model proposes, utilize the switching principle of filter, two tablet filters are switched back and forth, two filters work in respectively day and night, the filter on daytime stops infrared ray, makes color reduction, not colour cast, image is soft, night, filter was to allow infrared ray pass through, auxiliary camera insufficient light at night, compensation camera because of insufficient light, and do not see scenery, had ultrared subsidy, the scenery at night is more high-visible, to reversing, brings safety.
Accompanying drawing explanation
Fig. 1, the 2nd, the structural representation of the utility model on-vehicle night vision camera.
Wherein, 10 housings; 1 camera lens; 2 optical-filter switchers; 3650nm colored filter; 4850nm infrared filter; 20 master control circuit board; 5 illuminant modules; 6 pattern process modules; 7 video output display modules; 8 infrared lamps.
Embodiment
Below in conjunction with embodiment, further set forth the utility model:
As shown in Figure 1, 2, a kind of on-vehicle night vision camera, comprise housing 10, camera lens 1, optical-filter switcher 2, master control circuit board 20, the surrounding of described camera lens 1 is provided with infrared lamp 8, after camera lens 1, be provided with optical-filter switcher 2, infrared lamp 8, optical-filter switcher 2 are electrically connected with master control circuit board 20.Described master control circuit board 20 includes illuminant module 5, pattern process module 6 and video output display module 7.
As preferred version, described optical-filter switcher includes two filters, is respectively 650nm colored filter 3 and 850nm infrared filter 4, is respectively used to pass through at filtering on daytime infrared ray and night infrared ray.Utilize the switching principle of filter, two tablet filters are switched back and forth, two filters work in respectively day and night, and the filter on daytime stops infrared ray, make color reduction, colour cast not, image is soft, and night, filter was to allow infrared ray pass through, auxiliary camera insufficient light at night, compensation camera because of insufficient light, and do not see car rear scenery.
As preferred version, described optical-filter switcher includes transfer strip switch, and transfer strip switch is connected on plates lamp for vehicles both positive and negative polarity, opens license plate lamp, utilizes night license plate lamp as power supply, completes the switching of two filters after illuminant module induction.
Another execution mode, described optical-filter switcher can also have photo resistance and drive circuit, and this drive circuit and described master control circuit board are electrically connected, and automatically respond to and switch two filters.
Described optical-filter switcher can adopt above any one frame mode to complete the switching of filter.
But above-mentioned embodiment is exemplary, be to be this patent to be comprised to the restriction of scope in order better to make those skilled in the art can understand this patent, can not to be interpreted as; So long as according to spirit that this patent discloses do be anyly equal to change or modify, all fall into the scope that this patent comprises.
