Description
Technical field
The utility model relates to a kind of focusing system more particularly to a kind of infrared photography mould group active focusing systems.
Background technique
Since the 1970s, reaching its maturity with electronic technology, imaging technique and computer technology, and sense
Optical chip sensitivity, resolution ratio and in terms of advantage, CMOS camera technique rapidly developed and extensive
Applied to fields such as civil camera, medical apparatus, military surveillance and remote sensing telemeterings.Round-the-clock imaging of the people to CMOS camera
The requirement of energy is also higher and higher, and night vision system is come into being.
Night vision system can be divided into actively and passively two ways according to lighting source itself whether is provided: passive night vision system
Objective emission and the light of reflection are imaged using imaging device, the observation to target is realized, in no light or low-light (level)
Under conditions of, it is difficult that target is imaged；Active laser illumination image-forming assembly is taken the photograph by near-infrared semiconductor laser and CMOS
Camera composition, the two cooperate respectively as lighting source and image detector, optical axis and the angle of departure, reach not by environment
Illumination influences, to the purpose of low-light (level) target imaging.But existing active Night Vision Imaging System is in manufacture, detection process, closely
Infrared illumination system mostly uses transmission-type to illuminate, and is sequential illumination system, and the application illumination of such method and camera is not inconsistent, shadow
The focusing accuracy and image quality of camera are rung, and sequential illumination system frequency and duty ratio are non-adjustable, power consumption is relatively large.
Summary of the invention
In order to overcome drawbacks described above, the utility model provides a kind of infrared photography mould group active focusing system, close to reality
Border application illumination, not only increases camera focusing accuracy and image quality, while being conveniently adjusted illumination frequencies and duty ratio, reduces
Energy consumption.
The utility model is to solve technical solution used by its technical problem: a kind of infrared photography mould group is actively right
Burnt system, including chart board, lighting system, relay lens, camera lens, mechanical arm, imaging sensor and controller, the camera lens are fixed on
On the mechanical arm, the relay lens and chart board are sequentially arranged in outside the side of the camera lens, and described image sensor is set to described
Outside the opposite other side of camera lens；The lighting system is set to the relay lens periphery, and can issue infrared light to the chart board；
Described image sensor communication connects the controller, and the controller can control the lighting system and mechanical arm work.
The light source of the lighting system is high-frequency impulse control as a further improvement of the utility model, adjustable
Frequency and duty ratio reduce energy consumption.
The light source of the lighting system is narrowband infrared LED light source as a further improvement of the utility model,.
The beneficial effects of the utility model are: the infrared photography mould group active focusing system is infrared using high-frequency impulse control
Lighting system, not only the frequency and duty ratio of pulse are adjustable, substantially reduce energy consumption, and controller can be according to imaging sensor
Chart board image come control mechanical arm drive camera lens adjustment both position, optimum image plane is found, due to using narrowband infrared LED
Light source, reflective illumination, the practical application illumination with camera are more nearly, and greatly improve the focusing accuracy of camera module to mention
High camera module image quality.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model.
In conjunction with attached drawing, make the following instructions:
1 --- chart board；2 --- lighting system；
3 --- relay lens；4 --- camera lens；
5 --- mechanical arm；6 --- imaging sensor.
Specific embodiment
Below in conjunction with attached drawing, elaborate to a preferred embodiment of the utility model.But the guarantor of the utility model
Shield range is not limited to following embodiments, i.e., in every case with simple made by present utility model application the scope of the patents and description
Equivalent changes and modifications all still belong within the utility model patent covering scope.
It refering to fig. 1, is a kind of infrared photography mould group active focusing system described in the utility model, including chart board 1, illumination
System 2, relay lens 3, camera lens 4, mechanical arm 5, imaging sensor 6 and controller, camera lens 4 are fixed on mechanical arm 5, relay lens 3
It is sequentially arranged in chart board 1 outside the side of the camera lens, imaging sensor 6 is set to outside the opposite other side of camera lens；Lighting system 2 is set
In 3 periphery of relay lens, and infrared light can be issued to chart board；6 communication of imaging sensor connects the controller, and controller can
It controls the lighting system 2 and mechanical arm 5 works.
When work, lighting system 2 issues infrared light to chart board 1, and the infrared light which issues encounters chart board 1
Relay lens 3 is passed through after reflection and enters camera lens 4, and the image of chart board 1 is projected imaging sensor 6 by camera lens 4, and imaging sensor 6 will
Received picture signal sends controller to, and picture signal driving mechanical arm 5 adjusts camera lens 4 and image to controller based on the received
The relative position of sensor 6 is most preferably practised physiognomy with finding.
In addition, the light source of the lighting system is high-frequency impulse control, adjustable frequency and duty ratio, energy consumption is reduced.
The light source of the lighting system is narrowband infrared LED light source.
It can be seen that the infrared photography mould group active focusing system controls infrared illumination system using high-frequency impulse, not only
The frequency and duty ratio of pulse are adjustable, substantially reduce energy consumption, and controller can according to the chart board image of imaging sensor come
Control the position that mechanical arm drives both camera lens adjustment, to find optimum image plane, greatly improve camera focusing accuracy and at
Image quality amount.
