Description
Technical field
The invention belongs to a kind of image detecting method, and in particular to a kind of images flat degree inspection of 5,000,000 pixel CCD camera
Survey method.
Background technology
At present, intelligent transportation system carries the important of vehicle behavior monitoring as the important component of urban construction
Task.Meanwhile, with maintaining sustained and rapid growth for vehicles number, traffic accident, traffic congestion and the public security related to motor vehicle
Case is also being increased rapidly.Intelligent transportation system is for improving criminal case detection rate, alleviating traffic congestion, raising road
More and more important effect is played in terms of efficiency, government administration section is also more next for the attention degree of intelligent transportation system
It is higher.Therefore, especially traffic department of government agencies at all levels proposes more and more higher to the image definition and flatness at scene
Requirement.
Only have 5,000,000 pixel CCD on existing market（Charge Coupled Device, charge coupling device）Video camera
Planeness detection system, the system is excessively complicated, and input cost is higher, and software algorithm is not perfect enough, is easily caused erroneous judgement
Rate is too high, it is impossible to be well adapted for the market demand.
The content of the invention
The present invention be for above-mentioned technical problem, and propose a kind of 5,000,000 pixel CCD camera images flat degree inspection
Survey method.
The technical scheme is that：
A kind of images flat degree detection method of 5,000,000 pixel CCD camera, step is as follows：
CS adapter rings, 20 millimeters of camera lenses are first sequentially arranged in the CCD camera of 5,000,000 pixels, and CCD camera are put by I
In on camera tripod；
II is again connected 12V/3A power supplys with CCD camera, is connected CCD camera with portable computer by netting twine, opens
Portable computer, makes portable computer connect the video of CCD camera；
Then III is placed on ISO12233 definition cards on definition clamping stent 1 meter high, and make definition card distance
1.5 meters of CCD camera camera lens；
IV last regulation LED light supplement lamp, using the illumination around illumination photometer measuring resolution card, until illumination is maintained at
1000lux, adjusts the focus knob of camera lens, until image focus, is adjusted to highest by central sharp degree and be defined, checks figure
As marginal definition, so as to judge images flat degree.
A kind of specific regulating step of the images flat degree detection method of 5,000,000 pixel CCD camera is：
I first adjusts the focus knob of camera lens, by image according to 4:3 ratio match definition card size, and make in image
The vertical definition of the heart is more than or equal to 1500 demand pairs/millimeter, horizontal definition and is more than 1400 demand pairs/millimeter；
After II regulation picture centre definition, the marginal definition at four angles of image is observed by portable computer；If four
The vertical definition at individual angle is more than or equal to 1000 demand pairs/millimeter, horizontal definition and is more than 900 demand pairs/millimeter, judges figure
The flatness of picture is normal；Conversely, judging the flatness of image to be abnormal.
The beneficial effects of the invention are as follows：
The images flat degree detecting system and its method of the 5000000 pixel CCD cameras of the present invention, shooting can be judged rapidly
The flatness situation of system, Effective selection is carried out to defective products, it is to avoid occur that image or so is unclear or side at actual installation scene
The problem of edge is obscured, greatly shortens the video camera installation and debugging process of intelligent transportation field.
Brief description of the drawings
Fig. 1 is the schematic flow sheet of the present invention；
Fig. 2 is the ISO12233 definition cards of the present invention.
Embodiment
Hereinafter, referring to the drawings and embodiment the present invention is described in detail：
As shown in figure 1, a kind of images flat degree detection method of 5,000,000 pixel CCD camera of the present invention, step is as follows：
I is first sequentially arranged at CS adapter rings, 1 in2,0 millimeter of camera lens in the CCD camera of 5,000,000 pixels, and by CCD phases
Machine is placed on camera tripod；
II is again connected 12V/3A power supplys with CCD camera, is connected CCD camera with portable computer by netting twine, opens
Portable computer, makes portable computer connect the video of CCD camera；Portable notebook computer minimalist configuration is CPU：Inter
(R) the Duo CPU P8700@2.53GHz of Core (TM) 2, internal memory：4G；
Then III is placed on ISO12233 definition cards on definition clamping stent 1 meter high, and make definition card distance
1.5 meters of CCD camera camera lens；
IV last regulation LED light supplement lamp, uses the photograph around model FLUKE 941 illumination photometer measuring resolution card
Degree, until illumination is maintained at 1000lux, adjusts the focus knob of camera lens, until image focus, is adjusted with central sharp degree
It is defined to highest, check image marginal definition, so as to judge images flat degree.
As shown in Fig. 2 a kind of specific regulating step of the images flat degree detection method of 5,000,000 pixel CCD camera is：
I first adjusts the focus knob of camera lens, by image according to 4:3 ratio match definition card size, and make in image
The vertical definition of the heart is more than or equal to 1500 demand pairs/millimeter, horizontal definition and is more than 1400 demand pairs/millimeter, correspondence
" 15 ", " 14 " scale on ISO12233 definition cards；
After II regulation picture centre definition, the marginal definition at four angles of image is observed by portable computer；If four
The vertical definition at individual angle is more than or equal to 1000 demand pairs/millimeter, horizontal definition and is more than 900 demand pairs/millimeter, correspondence
" 10 ", " 9 " scale on ISO12233 definition cards, the flatness for the image that breaks is normal；Conversely, judging the flatness of image
For exception.
The images flat degree detecting system and its method of the 5000000 pixel CCD cameras of the present invention, shooting can be judged rapidly
The flatness situation of system, Effective selection is carried out to defective products, it is to avoid occur that image or so is unclear or side at actual installation scene
The problem of edge is obscured, greatly shortens the video camera installation and debugging process of intelligent transportation field.
