Embodiment
Below in conjunction with the drawings and specific embodiments the present invention is described in further detail.
As shown in Figure 1, the important collection that is used for image of imageing sensor (1), central processing unit (2) is important to be used for the image that imageing sensor (1) is gathered is handled and analysis of accounts, display module (3) is important to be used to show that count results and counting failure error message, keyboard load module (4) are mainly used in signals such as the On/Off of generator and enabling counting.
As shown in Figure 2, behind the paper side in alignment imageing sensor of operating personnel with estimated amount, open counter, system enters power-up initializing.System enters the cycle detection state subsequently, waits for and detect the enabling counting signal.After operating personnel press paper counting button in the lower keyboard load module (4), central processing unit (2) will detect this button and press, be that system detects signal arrival, the image that central processing unit (2) reading images sensor (1) is gathered is in Installed System Memory, carry out Flame Image Process and analysis of accounts then, finish tally function, and the result deposited in the viewing area, and control display module (3) net result that the viewing area is deposited shows on display unit, and prepares counting next time.
The system operation programs step is as follows:
A, system's power-up initializing.
B, wait detection signal.The system wait operating personnel press the paper counting button, when button is pressed, change step c over to, otherwise system are in the inquiry waiting status always.
C, system are read into imageing sensor (1) current shooting image in the Installed System Memory, and prepare to carry out image processing and analyzing.
D, system's starting Flame Image Process and routine analyzer, and finish Flame Image Process and analysis of accounts.
E, system show the result who deposits in the results display area on display module (4).
F, return step b, prepare to count next time.
As shown in Figure 3, imageing sensor (1) images acquired and be input to central processing unit (2) after, central processing unit (2) carries out Flame Image Process and analysis of accounts to the image of being gathered.
At first the image with input is divided into three zones of upper, middle and lower, respectively Flame Image Process and analysis of accounts is carried out in three zones then.When trizonal count results is identical, then counts successfully, and count results is stored in the viewing area is used for showing.Otherwise, think the counting failure error message to be stored in the viewing area.The concrete operations content of Flame Image Process and analysis of accounts comprises:
1. the filtering and noise reduction of image.Utilize Gauss's smoothing filter to come smoothed image to remove noise (promptly doing convolution) with Gauss's smoothing filter and image.
2. edge of image detects.Utilize the Canny operator to realize that edge of image detects, image is converted into bianry image after the rim detection.
3. isolated edge noise point filtering.The part isolated noise point is removed.Calculate the connected domain of each marginal point,, think that this marginal point is caused by noise, then removes this marginal point when connected domain during less than threshold value.
4. the inclination of image is corrected.Because the angle of input picture is not a vertical direction, therefore need be rotated rectification to image, the parallel edge oblique line after the image segmentation is modified to vertical straight line.
To the image rotating that makes correction for direction, the quantity of edge pixel forms histogram to concrete grammar in the every row pixel of each rotation back statistics for gradually.When certain is listed as histogrammic height greater than threshold value c
MaxThe time determine that this classifies edge columns as, when certain is listed as histogrammic height less than threshold value c
MinThe time determine that this classifies non-edge columns as.Carry out the number of edges statistics then.When adjacent column was edge columns, number of edges only added 1, and pairing RA is best RA when number of edges is maximum.Finish the inclination rotation of image corrects by this angle.
5. analysis count results.Number of edges after the rectification is this regional paper number of pages.If three determined numbers of pages in zone of upper, middle and lower are identical, then count successfully, otherwise the counting failure.
The program step of Flame Image Process and analysis of accounts is as follows:
The parameter initialization of a, Flame Image Process and analysis of accounts.
B, images acquired is divided into three zones by upper, middle and lower.
C, initialization area label i=1.
D, smothing filtering is carried out in i zone, remove noise spot, reduce noise effect.
E, rim detection is carried out in i zone.
F, the bianry image after the rim detection is carried out secondary filtering handle, remove the isolated noise marginal point.
G, the angle of inclination correction process is carried out in i zone.
The paper number of pages in h, i zone of calculating.
I, region labeling increase 1, i.e. i=i+1.
If j is i＞and 3, then counting operation is all finished in three zones of upper, middle and lower, then changes step k over to, otherwise changes steps d over to, carries out the analysis of accounts in next zone.
If the trizonal count results of k upper, middle and lower is identical, then count successfully, count results is stored in the viewing area, otherwise the counting failure is stored in the viewing area with error message.
L, Flame Image Process and analysis of accounts finish.
Imageing sensor among the present invention (1) adopts ccd video camera, and central processing unit (2) adopts single-chip microcomputer, and display module (3) adopts charactron or liquid crystal display, and keyboard load module (4) contains 2 buttons at least, i.e. on ﹠ off switch and enabling counting key.Handling procedure adopts C Plus Plus to write.
