Description
Technical field
The present invention relates to a kind of focusing system more particularly to a kind of infrared photography module active focusing systems.
Background technology
Since the 1970s, reaching its maturity with electronic technology, imaging technique and computer technology, and sense
In the advantage of sensitivity, resolution ratio and noise abatement etc., CMOS camera techniques are rapidly developed and extensive optical chip
Applied to fields such as civil camera, medical apparatus, military surveillance and remote sensing telemeterings.Round-the-clock imaging of the people to CMOS cameras
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 to be imaged to target；Active laser illumination image-forming assembly is taken the photograph by near-infrared semiconductor laser and CMOS
Camera forms, and the two cooperates with the angle of departure, reaches not by environment respectively as lighting source and image detector, optical axis
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 illumination, 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.
Invention content
In order to overcome drawbacks described above, the present invention provides a kind of infrared photography module active focusing system, closing to reality is answered
With illumination, camera focusing accuracy and image quality are not only increased, while being conveniently adjusted illumination frequencies and duty ratio, reduces energy
Consumption.
The present invention in order to solve its technical problem used by technical solution be：A kind of infrared photography module active focusing system
System, including chart board, lighting system, relay lens, camera lens, mechanical arm, imaging sensor and controller, the camera lens are fixed on described
On 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 the camera lens
Outside the opposite other side；The lighting system is set to the relay lens periphery, and can send out infrared light to the chart board；It is described
Imaging sensor communication connects the controller, and the controller can control the lighting system and mechanical arm work.
As a further improvement on the present invention, the light source of the lighting system controls for high-frequency impulse, can adjust frequency
And duty ratio, reduce energy consumption.
As a further improvement on the present invention, the light source of the lighting system is narrowband infrared LED light source.
The beneficial effects of the invention are as follows：The infrared photography module active focusing system controls infrared illumination using high-frequency impulse
System, not only the frequency and duty ratio of pulse are adjustable, substantially reduce energy consumption, and controller can be according to the figure of imaging sensor
Project picture comes the position of both control machinery armband index glass head adjustment, optimum image plane is found, due to the use of 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 improve
Camera module image quality.
Description of the drawings
Fig. 1 is schematic structural view of the invention.
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 implementation mode
Below in conjunction with attached drawing, elaborate to the preferred embodiment of the present invention.But protection scope of the present invention is not
Be limited to following embodiments, i.e., in every case with simple equivalence changes made by scope of the present invention patent and description with repair
Decorations, all still belong within patent covering scope of the present invention.
Refering to fig. 1, it is a kind of infrared photography module active focusing system of the present invention, including chart board 1, lighting 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 and figure
Plate 1 is sequentially arranged in outside the side of the camera lens, and imaging sensor 6 is set to outside the opposite other side of camera lens；During lighting system 2 is set to
After 3 periphery of mirror, and infrared light can be sent out to chart board；6 communication of imaging sensor connects the controller, and controller can control
The lighting system 2 and mechanical arm 5 work.
When work, lighting system 2 sends out infrared light to chart board 1, and the infrared light which sends out encounters chart board 1
Relay lens 3 is passed through to enter camera lens 4 after reflection, the image of chart board 1 is projected imaging sensor 6 by camera lens 4, and imaging sensor 6 will
The picture signal of reception sends controller to, and controller drives mechanical arm 5 to adjust camera lens 4 and image according to the picture signal of reception
The relative position of sensor 6 is most preferably practised physiognomy with finding.
In addition, the light source of the lighting system controls for high-frequency impulse, frequency and duty ratio can be adjusted, reduces energy consumption.
The light source of the lighting system is narrowband infrared LED light source.
It can be seen that the infrared photography module 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 machinery armband index glass head adjustment both position, to find optimum image plane, greatly improve camera focusing accuracy and at
Image quality amount.
