Description
Technical field
The present invention relates to coal mine safety monitoring fields, and in particular, to a kind of mine supervision image enhancement processing method.
Background technique
Safety of coal mines is always the problem of paying close attention to of colliery industry, with advances in technology and develops, utilizes modernization
Monitoring device substitute the characteristics of traditional artificial monitoring has been Modern coal mines industry.
Mine supervision system can obtain the monitoring image of colliery scene, and for rear end, staff is checked, however due to coal
Mine site environment is complicated, causes mine supervision picture quality poor, is not easy to staff and checks, each in practical application
Part is likely to that image quality is caused to be deteriorated, and the information for transmitting image normally can not be read and be identified.For example, acquiring
Cause image global illumination uneven or Image Acquisition system due to light environment or body surface are reflective etc. in image process
The limitation of the unavoidable addition acquisition noise of reason or image display united in collection process due to mechanical equipment
Property cause image displa layer time sense to reduce or color reduction etc..
Much since the visual effect of the influence image taking of scene condition is bad, this just needs image enhancement technique to change
Certain features of target object in the visual effect of philanthropist, such as prominent image, the feature that object is extracted from digital picture
Parameter etc., these are all conducive to the identification, tracking and understanding to target in image.Image enhancement processing to the effect that protrudes
Unwanted information is weakened or removed in interested part in image.Useful information is set to be strengthened in this way, to obtain one kind
More practical image is converted into a kind of image for being more suitable for people or machine is analyzed and processed.
The gray level of image is reduced after existing mine supervision image is converted, and causes certain detailed information not obvious enough
It even disappears, therefore, it is necessary to carry out image enhancement processing to mine supervision image, but in the prior art only in backend computer
Image enhancement processing is carried out to mine supervision image, for bad environments, if illumination condition is unsatisfactory for or too strong environment, image
Enhancing treatment effect is not obvious.
Summary of the invention
The present invention provides a kind of mine supervision image enhancement processing method, solves and only calculated in the prior art in rear end
Machine carries out image enhancement processing to mine supervision image, for bad environments, if illumination condition is unsatisfactory for or too strong environment, and figure
The technical issues of image intensifying treatment effect is not obvious realizes computer graphic image intensifying processing method and practical illumination condition
Adjusting method combines, and the preferable mine supervision image of picture quality can be also obtained in the case where actual environment is severe
Technical effect.
For achieving the above object, this application provides a kind of mine supervision image enhancement processing method, the methods
Include:
Step 1: obtaining mine supervision image, picture quality judgement is carried out to the picture quality of mine supervision image, if coal
The picture quality of mine monitoring image is qualified, then is shown in mine supervision system；If the picture quality of mine supervision image
It is unqualified, then follow the steps 2；
Step 2: to mine supervision image carry out image enhancement processing, to the mine supervision image after image enhancement processing into
The judgement of row picture quality carries out in mine supervision system if the mine supervision picture quality after image enhancement processing is qualified
Display；If the mine supervision picture quality after image enhancement processing is unqualified, 3 are thened follow the steps；
Step 3: the mine supervision image after image enhancement processing being analyzed, the image for obtaining mine supervision image is bright
Spend distributed intelligence；

Row adjustment.
Wherein, the principle of this method are as follows: acquisition mine supervision image first carries out the picture quality of mine supervision image
Picture quality judgement, that is, judge that image is whether quality needs to enhance, and can save operation time and process if not needing, if coal
The picture quality of mine monitoring image is qualified, then is shown in mine supervision system；If the picture quality of mine supervision image
It is unqualified, then image enhancement processing is carried out to mine supervision image, figure is carried out to the mine supervision image after image enhancement processing
As Quality estimation, if the mine supervision picture quality after image enhancement processing is qualified, shown in mine supervision system；
If the mine supervision picture quality after image enhancement processing is unqualified, even picture quality or unqualified after enhancing processing, that
Then judge that site environment is severe, using live illumination Adjusted Option, the mine supervision image after image enhancement processing is carried out
Analysis obtains the image brightness distribution information of mine supervision image, that is, analyzes where excessively dark where excessively bright in picture；Then base
In the image brightness distribution information of mine supervision image, generate the brightness of image Adjusted Option of mine supervision image, i.e., it will be excessively bright
The intensity of illumination in place reduce, the intensity of illumination in excessively dark place is enhanced；The image for being then based on mine supervision image is bright
Adjusted Option is spent, the illumination brightness of colliery scene and direction are adjusted.
Further, the method also includes steps 6: after the illumination brightness and direction for obtaining colliery scene are adjusted
Mine supervision image carries out picture quality judgement to the picture quality of mine supervision image, if the image matter of mine supervision image
Amount is qualified, then is shown in mine supervision system；If the picture quality of mine supervision image is unqualified, alerted,
Adjustment does not come then to be alerted, and otherwise will affect Field Monitoring System operational effect.
