The utility model discloses an it can read dynamic bar code to read the ware, and discerns the success rate height, has better application prospect.
Description
Technical field
The utility model relates to a kind of bar-code reader, especially a kind of bar-code reader of twin-lens.
Background technology
At present, the implementation of barcode technology is all the mode based on digital image acquisition and process substantially, is gathered the bar code image of identified thing by digital camera original paper, through image procossing and decoding, realizes the Data Enter to identified thing.In each scene of bar code application, the emphasis of the dynamic identified object of Fast Reading Shi Ge manufacturer research always.
The main cause that bar code in rapid movement is difficult to be identified is: (1) picture pick-up device time for exposure is long, causes bar code in rapid movement cannot blur-free imaging; (2) the old transducer of lining by line scan can produce distortion in shooting Moving Objects process; (3) when the photoreceptor central area that shooting effect is best is mapped to photographic subjects region, scope is very little, and when camera frame per second is not enough, motion bar code is too short in this region time of staying, cannot form effective shooting.
Traditional image-type bar-code reader effective reading scope is very little, and in the single picture transmission time, if reading object moves too fast, object has likely shifted out effective reading scope, thus causes skip.If by reading range and the frame per second of the reader of the single camera of increase, then shooting part cost index level can be caused to increase, and installation volume is uncontrollable.
As can be seen from analysis, solve fast dynamically the most basic the starting with of reading and be a little the optical imaging moieties of equipment.At present, the thinking that each bar code reader manufacturer addresses this problem mainly updates digital camera original paper, to photographing the bar code image of more clear standard.At present, price is high because the cost of IMAQ part limits to adopt the bar code reader of high-speed camera head, or cannot accomplish intensive installation because of the bulky of image acquisition component.
Summary of the invention
The technical problems to be solved in the utility model be existing bar-code reader when reading the bar code in rapid movement, read success rate low.
In order to solve the problems of the technologies described above, the utility model provides a kind of twin-lens high speed dynamic bar codes reader, comprises the first camera, second camera, the first decoder, the second decoder and control board; Control board is provided with microprocessor and supply module; First camera is connected with the second decoder with the first decoder by controls transfer data wire respectively with second camera; First decoder is connected with microprocessor by transmission power supply winding displacement with the second decoder; Supply module is respectively the first camera, second camera, the first decoder, the second decoder and microprocessor power supply.
Adopt Microprocessor S3C44B0X first camera and second camera to hocket IMAQ transmission, under the identical sampling time, effectively can improve the efficiency of bar code reading, even if when bar code is dynamic, also can guarantee bar code reading success rate; Adopt the first decoder and the second decoder to carry out independent decoding to the first camera and second camera respectively, improve decoding efficiency, effectively prevent decoding problem by mistake.
As the further restriction scheme of bar-code reader of the present utility model, the first camera and second camera are for laterally or being longitudinally close to setting side by side.First camera and second camera position are so arranged, can prevent the image of the first camera and second camera collection from occurring bigger difference, thus guarantee that dual camera interleaved acquisition normally runs.
The beneficial effects of the utility model are: (1) adopts Microprocessor S3C44B0X first camera and second camera to hocket IMAQ transmission, under the identical sampling time, effectively can improve the efficiency of bar code reading, even if when bar code is dynamic, guarantee bar code reading success rate; (2) adopt the first decoder and the second decoder to carry out independent decoding to the first camera and second camera respectively, improve decoding efficiency, effectively prevent decoding problem by mistake.
Accompanying drawing explanation
Fig. 1 is reader dual-camera structure of the present utility model;
Fig. 2 is circuit structure of the present utility model.
In figure: 1, the first camera, 2, second camera, 3, controls transfer data wire, the 4, first decoder, the 5, second decoder, 6, transmission power supply winding displacement, 7, control board.
Embodiment
As illustrated in fig. 1 and 2, twin-lens high speed dynamic bar codes reader of the present utility model comprises: the first camera 1, second camera 2, first decoder 4, second decoder 5 and control board 7.
Wherein, control board 7 is provided with microprocessor and supply module; First camera 1 is connected with the second decoder 5 with the first decoder 4 by controls transfer data wire 3 respectively with second camera 2; First decoder 4 is connected with microprocessor by transmission power supply winding displacement 6 with the second decoder 5; Supply module is respectively the first camera 1, second camera 2, first decoder 4, second decoder 5 and microprocessor power supply; First camera 1 and second camera 2 are for laterally or being longitudinally close to setting side by side.
Twin-lens high speed dynamic bar codes reader of the present utility model is when reading, Microprocessor S3C44B0X first camera 1 and second camera 2 carry out image sampling/transmission with beat over-over mode, even if when bar code is dynamic, always have a camera and can collect bar code image, and respectively image is transferred to the first decoder 4 and the second decoder 5 be connected with the speed of 60fps; First decoder 4 and the second decoder 5, after receiving transmitting image, carry out decoding respectively and attempt, and after having any one decoders decode success, terminate this bar code reading.In reading process, the transmission rate of whole reader comprehensively reaches 120fps, and this is in the industry cycle very leading; Simultaneously through experiment, 99% success rate when the dynamic reading rate of reader of the present utility model has brought up to 70cm/s from 95% success rate during original 35cm/s, promotes Be very effective.
