Description
Technical field
The invention belongs to the image recognition technology field, be specifically related to the hit telling system that a kind of method that has adopted image to process is carried out the automatic identification calculating of scoring ring.
Background technology
Along with the progress of information technology, computer network and correlation technique incorporate sports field just fast.In present gunnery meeting, indication of shots mainly relies on artificial interpretation or mechanical type is measured, and its process is loaded down with trivial details, and efficient is low, labor intensive, and it is also not accurate enough, controversial easily to gather achievement.
The present invention has adopted image to process the method that combines with embedded technology, designs a kind of shooting automatic scoring round target system based on the DSP technology.It is dissolved into the present computer technology, wire/radio network access technology, database design technique, IMAQ and treatment technology and embedded development technology in this design, and integrated level is higher, and cost is low, and operation is succinct, is easy to layout.
Summary of the invention
This goal of the invention provides some drawbacks that a kind of shooting automatic scoring round target system based on image recognition overcomes the Traditional Man indication of shots, ensures fairness, reliability and the rapid and convenient of match.
The technical scheme that realizes the object of the invention is: a kind of shooting automatic scoring round target system based on image recognition, the method that this system adopts image to process is carried out the automatic identification of scoring ring and is calculated, it is characterized in that, this system comprises: front end indication of shots module, formed by CCD camera, image reception, view data buffer memory (SDRAM), dsp chip, a receipts/module, display terminal, receive the instruction of control centre, the correct operation of control IMAQ is finished image recognition and shooting grade is delivered to control centre by wireless network;
Control centre, produce and safeguard database, management match process, the arrangement of finishing shooting personnel setting and order, printing games results and other form and the double server of doing the whole system network of gunnery meeting, coordinate the operation of whole system, remote inquiry is provided.
As a further improvement on the present invention, gathering storage in the described front end indication of shots module adopts the DMA transmission technology ccd signal to be processed the adjustment collection storage that realizes the CCD data signal.
As a further improvement on the present invention, the following step is carried out in described information gathering storage (DMA): the output control terminal of (1) 8D buffer connects the R/W signal, the R/W signal is also by the ternary buffer control DMA of 88 lines and computer data bus passage, it is identical to clap the distributor output timing for two 8, address generator is 16, distributor is clapped in low 3 inputs 8, and high 13 input RAM are so 8 groups of address rams of per 8 clock pulses rise one simultaneously;
(2) for each of CCD video counts value signal of input successively, can only be by being clapped one group of 8D buffer unloading that distributor is put "+" by 8, the unloading time is 20ns, stabilization process when the data signal of unloading comprises unloading, because the output of 8D buffer is in allowing output state, can appear in the lump on the output line, but be in selection outside (CS=1) with the corresponding RAM of above-mentioned 8D buffer this moment, RAM is in and refuses to deposit state, after the next clock input that and if only if, just be in write state, therefore, only deposit buffer in 20ns for the numerical signal that is input to each time CCD, begin simultaneously RAM is write, write time to RAM reaches 700ns, realizes the data high-speed transmission.
As a further improvement on the present invention, medium filtering is adopted in the preliminary treatment of described image, effectively leaches the noise among the target figure, improves the quality of target figure.
As a further improvement on the present invention, the Threshold segmentation of described image adopts the method for many Threshold segmentations, there is the gray scale in three places that obvious difference is arranged among the target figure: target disc, scoring ring line and background, shell hole, wherein the maximum scoring ring line of the gray scale of shell hole takes second place, if two threshold values are Y1, Y2, according to above-mentioned theory, the image of getting after the threshold value may be defined as:
What so just be perfectly clear separates target disc, scoring ring line, shell hole, has made things convenient for the follow-up target work of declaring.
As a further improvement on the present invention, the thinning algorithm that described calculating shell hole number of rings adopts Hilditch to propose, eight neighborhood p of definition pixel p
i(0≤i≤7) associated number is: N
c=Σ (N
K-1, N
k, N

i≤ 1 o'clock, N
i=0, otherwise N
i=1, the associated number N of pixel p
cClaimed that p was Multiple Pixels at=1 o'clock.
When object pixel P satisfies following condition: P simultaneously
0+ P
2+ P
4+ P
6≤ 3; N
c=1; P
iIn have a unlabelled object pixel at least;
P
2=1 or
P
4=1 or
Then pixel p, is deleted all pixels that are labeled as m behind an end of scan concurrently for can delete pixel (for example being labeled as m), draws the refinement figure line.
After obtaining the scoring ring line, centered by target center, scan according to a certain direction the scoring ring value, then do average computation, draw the radius r of each ring of scoring ring line
i, last according to the shell hole of separating in the medium filtering, scanning obtains the hole heart (M, N) of shell hole, and shell hole can be tried to achieve by following formula to the distance of target center:
With D
RWith the scoring ring line radius r of calculating
iWhich ring contrast is determined shell hole in, thereby is drawn shooting grade.
The method that the present invention has adopted image to process is carried out the automatic identification calculating of scoring ring, and the on-the-spot information issue of shooting is transmitted by the wireless network access and realized, has improved the applicability of system.This system has overcome some drawbacks of Traditional Man indication of shots, at fairness, reliability, rapid and convenient aspects some superiority is arranged, and in the gunnery meeting in-situ processing, can reach more satisfactory effect.
Beneficial effect of the present invention is:
(1) DSP adopts Harvard's bus (HARVARD) structure of 16, and highly-parallel arithmetic has the 40MPIS instruction execution speed, has the multiply accumulating instruction, so that ordering calculation efficient is high, speed is fast;
