Abstract
The utility model discloses an adopt railway contact net image device of blue light as light source. An object of the utility model is to provide an adopt railway contact net image device of blue light as light source. The utility model discloses a 4C supporting arrangement, filter, camera lens and blue -light source, its characterized in that: the filter is located between 4C supporting arrangement and the camera lens, and 4C supporting arrangement's downside is equipped with the blue -light source. Is the blue ray that the blue -light source sent that single wavelength is 400 500nm's blue ray. The utility model discloses mainly used adopts the blue light to form images to the railway contact net as the light source.
Description
Technical field
The utility model is related to a kind of imaging device, more particularly to a kind of use blue light as light source railway contact line into
As device.
Background technology
With developing rapidly for domestic railway, how efficient safety problem and failure that rail track occurs are detected
Hidden danger has been extremely urgent.At present, to the imaging of contact net suspension status detection monitoring device (4C) using LED and xenon lamp
White light source is used as imaging source.Up to the present, application of the blue-light source of single wavelength in 4C is blank out.
White light source as 4C light emitting source, there is aberration, cause image quality unintelligible in camera lens；Non- blue light shines
It is mapped in unlike material or the different identical material of newness degree, the picture of imaging has different differences, causes under-exposure
Or excessively；On daytime, because the influence of lamp is larger, there are problems that photo unsharp；When there is water on subject surface
During layer, most of visible ray is only absorbed by the water, and shooting effect is undesirable, and blue light farthest reduces effect shadow of the water to shooting
Ring.In order to solve the unsharp problem of image quality, the utility model uses single wavelength (400~500nm) blue light conduct
The light emitting source of 4C, can effectively solve the problem.
The content of the invention
The purpose of this utility model is the railway contact line imaging device for providing a kind of use blue light as light source, with gram
The drawbacks of clothes using white light source due to being brought.
To achieve the above object, technical solution of the present utility model is：A kind of use blue light as light source railway
Contact net imaging device, including 4C supports device, filter, camera lens and blue-light source, it is characterised in that：The filter 2 is located at 4C
Support between device 1 and camera lens 3,4C supports to be provided with blue-light source 4 on the downside of device.
The blue ray 5 that the blue-light source 4 sends is the blue ray that single wavelength is 400-500nm.
The beneficial effects of the utility model are：
1. the utility model provides a kind of railway contact line imaging device of use blue light as light source.White light is a kind of multiple
Coloured light, by various monochromatic light compositings.Camera lens can not be the light focusing of different wave length to same focal plane, so as to form color
Difference.After light passes through camera lens, water chestnut mirror decomposition of white light into different colours (wavelength) light, the light of different wave length can not be
Focused in same focus, so as to cause the problem of camera lens aberration, prevent railway contact line from being effectively identified.This practicality is new
The light source that type is imaged using a kind of single wavelength (400~500nm) blue light as 4C, the light of single wavelength can be same
Focused in focus, camera lens aberration can be effectively solved the problems, such as, so as to lift the recognition effect of railway contact line.
2. non-blue light is irradiated in unlike material or the different identical material of newness degree, and the picture of imaging has difference
Difference, cause under-exposed or excessively.Non- blue light is irradiated in unlike material or the different identical material of newness degree, warp
Cross different, clear so as to the cause picture quality blur margin problem of the light color formed after diffusing reflection.The utility model
The light source being imaged as 4C using a kind of single wavelength blue light, can become more fully apparent image tablet quality edge.
3., on daytime, natural lighting is mapped to camera lens, after imaging surface imaging, the intensity effect camera aperture of light
Size.Light is stronger, bigger using aperture so that images thicken unclear.The utility model is using a kind of single
The light source that wavelength blue light is imaged as 4C, single blue light is irradiated to camera lens, after imaging surface imaging, due to single ripple
Than relatively low, aperture diminishes the light intensity of blue light long, so that imaging picture becomes apparent from.
4. water is 100 times of blue light to the absorptivity of feux rouges, and blue light can play good reflecting effect to subject, be beneficial to
Imaging.The light source that the utility model is imaged using a kind of single wavelength blue light as 4C, can effectively be imaged.
By experiment：Image quality definition can be obtained as the light source that 4C is imaged using single wavelength blue light
Photo high.
Brief description of the drawings
Fig. 1 is the structural representation as the railway contact line imaging device of light source using single wavelength blue light.
Fig. 2 is the structural representation as the railway contact line imaging device of light source using white light.
In figure：1-4C supports device, 2- filters, 3- camera lenses, 4- blue-light sources, 5- blue rays, 6- focal planes, 7- whites
Light source, 8- white lights.
Specific embodiment
The utility model and its specific embodiment are described in further detail below in conjunction with the accompanying drawings.
Referring to Fig. 1, the utility model includes that 4C supports device, filter, camera lens and blue-light source, it is characterised in that：It is described
Filter 2 is located at 4C and supports between device 1 and camera lens 3, and 4C supports to be provided with blue-light source 4 on the downside of device.
The blue ray 5 that the blue-light source 4 sends is the blue ray that single wavelength is 400-500nm.
Single wavelength blue light illumination supports device to 4C, and influence of the other light sources to being imaged is filtered by filter, can drop
The influence of low sunshine on daytime, the light of filter treatment forms clearly image by lens reflex to focal plane.
Referring to Fig. 2, Fig. 2 is the structural representation as the railway contact line imaging device of light source using white light.Work as white light
When being irradiated to 4C support devices, the light for reflecting different wave length passes through lens reflex to focal plane, it can be seen that not
The light of co-wavelength will not be focused perfectly on focal plane, so as to clearly picture cannot be formed.
