For disadvantages mentioned above existing for prior art, applicant is studied and improved, there is provided one kind is based on image procossing
Note detection eliminating system.The defects of system can exist to variety classes paper is detected and rejected, and avoids
Substandard product flows into next process.The utility model uses following scheme：
A kind of note detection eliminating system based on image procossing, including：Optoelectronic switch, high-definition camera, open with photoelectricity
Close and the connected image acquisition units of high-definition camera, the graphics processing unit and image that are connected with image acquisition units at
Reason unit be connected and by graphics processing unit control pick mechanism of paper, the simultaneously bi-directional data of being connected with graphics processing unit it is tactile
Touch screen.
Further improvement as above-mentioned technical proposal：
Image acquisition units use FPGA, realize the high speed acquisition to image.
Graphics processing unit uses DSP, realizes the high speed processing to image.
It is the mechanism that high pressure air jet nozzles are controlled using air-operated solenoid valve to pick mechanism of paper, is carried out using the gases at high pressure of nozzle
Reject.
As control interface, touch-screen includes paper kind select button, start button, stop button, SR.Paper kind is selected
The feature database of different paper kinds can be transferred by selecting button, for detecting and rejecting.Start button, stop button direct control system open
Stop.SR is that the number of paper and bad product rate data of a cycle are initialized.
It is of the present utility model to have technical effect that：
For traditional inspection mode workload is big, efficiency is low and the present situation such as existing equipment complex designing, costly, this
The automaticity of utility model is high, it is possible to reduce and inspector hard work amount, greatly improve and select paper efficiency, and cost is low,
It is reliable, provide Reliable guarantee to improve product quality.

Embodiment
Specific embodiment of the present utility model is described further below in conjunction with the accompanying drawings.
As shown in Figure 1 and Figure 2, the note detection eliminating system based on image procossing of the present embodiment, including：Optoelectronic switch
1st, high-definition camera 2, the image acquisition units 3 and the phase of image acquisition units 3 that are connected with optoelectronic switch 1 and high-definition camera 2
Graphics processing unit 4 even, it is connected with graphics processing unit 4 and picks mechanism of paper 5 and image by what graphics processing unit 4 controlled
Processing unit 4 is connected and the touch-screen 6 of bi-directional data.
When system works, paper kind and flowing water linear velocity are set first on touch-screen 6, then presses start button, entirely
System enters working condition.Paper enters collection site in the presence of material conveyer belt, optoelectronic switch 1 detects carry out paper after,
" carrying out paper " signal is sent to image acquisition units 3, synchronization high-definition camera 2 gathers under the immediate record of image acquisition units 3
Paper image.Due to acquisition zone paper maximum speed up to 6 m/s, in the case of such high speed, how at a high speed and
It is extremely important that logistics image information is obtained without distortion, therefore system is up to the high-resolution of 9600 lines/second using line scanning frequency
Power RGB line array CCD camera.
Image acquisition units 3 are using FPGA as data buffering and logic control element.For high speed paper detection image data
Measure the characteristics of big, system realizes the caching of a frame image data using ping-pong operation, to reach requirement of the system to real-time.Figure
Picture processing unit 4 receives the paper image from image acquisition units 3 and detected using DSP as core.DSP not only has
Programmability, and the speed of its real time execution is considerably beyond general purpose microprocessor, especially suitable for Digital Image Processing.
Mainly the sand holes of paper, pleat, slurry scar etc. are identified using template matching method for graphics processing unit 4, and are tied
The method for closing Characteristic Extraction, on the premise of recognition accuracy is ensured, improves the efficiency of template matching algorithm.Template matches master
To include image preprocessing, defect classification, flaw and accurately match several steps.Image preprocessing is to carry out one to the image of input
Series of transformations processing, the method for use is image binaryzation, and gray-scale map is converted into the image for comprising only two kinds of gray values, a kind of
For background, another kind is flaw to be identified.Flaw includes sand holes, breach, pleat, slurry scar etc., and different flaws has different
Feature, it is quickly and efficiently classified, the flaw scope of next step template matches can be substantially reduced, lifting system
Recognition speed.Finally by exact matching algorithm, quantity and the position of various flaws are obtained, so as to determine underproof paper
.
The final executing agency that mechanism of paper 5 is whole system is picked, high pressure air jet nozzles mechanism is controlled using air-operated solenoid valve,
It is made up of air-operated solenoid valve and supporting control circuit.Air nozzle（Air-operated solenoid valve）It is transversely mounted on apart from collection site
15cm region.After graphics processing unit 4 detects side run paper, exporting " rejecting " signal immediately makes air-powered electromagnetic valve actuation
Make, high pressure draught is hit paper by air nozzle, so as to complete the whole process for detecting and rejecting.When paper presses 6 m/s
Speed flowing when, the response frequency of magnetic valve should be greater than 600Hz.
Touch-screen 6 is control and the monitoring interface of whole system, as shown in Fig. 2 including paper kind select button, starting and pressing
Button, stop button, SR.Paper kind select button can transfer the feature database of different paper kinds, for detecting and rejecting.Startup is pressed
The start and stop of button, stop button direct control system.Touch-screen, which can be monitored in a cycle, have been examined paper, has rejected paper, bad product rate
Etc. data, SR is that the number of paper and bad product rate data of a cycle are initialized.
In the utility model, the kicking paper machanism of nozzle-type is conventional structure, therefore the utility model is not described in detail.Photoelectricity is opened
Close 1, high-definition camera 2, image acquisition units 3, graphics processing unit 4, touch-screen 6 and be similarly prior art.
Embodiment of the present utility model is the foregoing is only, not thereby limits the scope of the claims of the present utility model, it is every
The equivalent structure or equivalent flow conversion made using the utility model description, or directly or indirectly it is used in other phases
The technical field of pass, similarly it is included within scope of patent protection of the present utility model.
