Description
Technical field
The utility model relates to the test of the low-light (level) of camera, especially a kind of environment simulator of low-light (level) test,
A kind of energetic uniform low-light (level) test environment can be simulated.
Background technique
Currently, the low-light (level) performance requirement for camera is higher and higher, it is often necessary to test the even lower illumination of 1Lux
Performance.But the satisfactory quantization of construction one and uniformly low light environment are to be increasingly difficult to, or spend suitable
Big cost can just manufacture.
The utility model, which proposes, counts a kind of test environment for using simple device, achieving the purpose that simulate low-light (level), should
Device is not only easy to operate, and low to the technical requirements of environment, can all meet the test request under camera low-light (level).
Summary of the invention
To solve the one or more defects mentioned in background technique, the utility model proposes a kind of tests of low-light (level)
Environment simulator.
A kind of environment simulator of low-light (level) test, including a light box, a test card, several couples of adjustable light sources, one
Dim light mirror, a closing magazine, a fixed device, a camera, power supply and display screen；The test is fastened in the front side of light box
Wall, several pairs of adjustable light sources are respectively provided at the left and right sides inner wall of light box, and the front side of the closing magazine is equipped with opening, dim light
Mirror is located at open front side, and camera is mounted in closing magazine by fixed device, and camera harness irradiates after passing through dim light mirror
In test card in light box, the power supply is camera power supply, and vision signal is transferred to display screen by the camera；Pass through
Fixed device adjustment camera is adjusted at a distance from dim light mirror, and adjusts the intensity of several pairs of adjustable light sources, to obtain
Low-light (level) tests the test card graphic under environment.
The fixed device will be determined according to the structure of camera, as long as not influencing the field range of camera, material is not
It is reflective, do not influence brightness.
Preferably, it can be equipped with idler wheel in the bottom of fixed device, or is equipped with skid, it is convenient to be fixed by mobile
Device adjusts the relative position (distance) between camera and dim light mirror.
Preferably, low luster coating can be smeared in fixation device surface, or uses dumb light pad pasting.
The sealing structure of magazine is closed, shape is unlimited, closes the outside installation dim light mirror of magazine, suitable hole location is stayed in inside
It is passed through to the harness of camera (externally connected with display screen and power supply).
The type of the adjustable light source of adjustable light sources such as adjusts colour temperature, brightness, its working principle is that:
(1) color-temperature regulating is realized by changing the ratio that do not share the same light.Such as increasing feux rouges, colour temperature warms；Increase blue
Light, colour temperature turn cold.
(2) it is to flow through the size of current of LED by change to realize that LED light, which adjusts brightness,.Electric current is more greatly, just brighter；
Otherwise it is just dark.And the adjusting of electric current, it is realized with PWM is changed.So-called PWM is exactly pulse width adjustment.Pulse width
The method of adjustment, the most fundamental is the numerical value for changing the resistance and capacitance that determine its width.The product of RC is big, then width can be big
A bit.General halogen bulb or fluorescent tube, which adjust brightness, to be controlled by adjusting light bulb/fluorescent tube size of current.
Dim light mirror is above the optical glass by superelevation finish using superelevation degree of polarization, the light polarizing film mistake of high pass rate
Optical filtering line, in the utility model, dim light mirror uses being ok with fixation multiple or adjustable multiple.
Compared with prior art, the utility model has the beneficial effects that a kind of the utility model provides structure simple, behaviour
Make the environment simulator of convenient low-light (level) test, the device is not only easy to operate, and low to the technical requirements of environment, can be all
Meet the test request under camera low-light (level).
