Abstract
The invention discloses a decoding system for enhancing machine vision contrast. The decoding system for enhancing the machine vision contrast comprises a decoding equipment body, a decoder, a camera device and an illumination source are mounted in the decoding equipment body, the decoder is connected with the camera device through a data line, the illumination source is a three-primary color light source which is capable of switching monochromatic sources, and the illumination source is further connected to an adjustment controller used for adjusting light source output. According to the decoding system for enhancing the machine vision contrast, an illumination source of two-dimension code reading equipment is replaced by illumination equipment with the three-primary colors, namely, red, blue and green as light sources, when the decoding equipment reads codes, normally used light sources are switched in sequence through the adjustment controller, when a camera shoots an image with the strongest contrast, the purpose of decoding is achieved, the efficiency and accuracy of the decoding are increased, and the decoding system for enhancing the machine vision contrast is suitable for majority decoding equipment.
Description
Technical field
The present invention relates to a kind of decoding device, particularly a kind of decode system that strengthens machine visual contrast.
Background technology
Quick Response Code reading code equipment is in understanding Quick Response Code process, adopt image-type coding/decoding method, utilize camera to take pictures to Quick Response Code is clear, reach decoding object, the Quick Response Code of high-contrast is the requirement of decoding, camera is in the process of taking pictures, and the selection of light source colour has determined whether photo contrast is clear and can reach solution code requirement.Generally, if use black and white camera, again the color of testee is selected not have special requirement, red (660nm) is proper selection.Because the wavelength of red LED is the sensitivity peaks of proximity transducer more, if carry out colour imaging, conventionally consider to use white light source, but adopt any light source, in decode procedure, all may run into the case that can not decode, as select red LED lamp to throw light on, be radiated at while take the Quick Response Code that green is background color, black and white camera is rendered as black by color, causes taking normal contrast photo.When irradiating red Quick Response Code, black and white camera is rendered as white by color, allows the reading code equipment also cannot be correctly appropriate.
Summary of the invention
In order to overcome above-mentioned defect, the invention provides a kind of decode system that strengthens the reading capability of Quick Response Code reading code equipment.
The present invention for the technical scheme that solves its technical problem and adopt is: a kind of decode system that strengthens machine visual contrast, comprise decoding device body, in described decoding device body, decoder, camera head and radiation source are installed, described decoder is connected with camera head by data wire, described radiation source is the three primary colors light source of changeable monochromatic source, and described radiation source also connects one for regulating the conditioning controller of light source output.
As a further improvement on the present invention, the front end of described radiation source is also respectively equipped with and is connected with ruddiness inductor, blue light inductor and gold-tinted inductor.
The invention has the beneficial effects as follows: the present invention is by the radiation source of Quick Response Code reading code equipment, become with three primary colors, redness, blueness, green is the irradiation apparatus of light source, when decoding device reads, by conditioning controller, convert successively conventional light source, at camera, clap while getting the strongest picture of contrast, reach the object of decoding, the efficiency and the accuracy that increase decoding, be applicable in most decoding devices.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
In figure, indicate: 1-decoding device body; 2-decoder; 3-camera head; 4-radiation source; 41-ruddiness inductor; 42-blue light inductor; 43-gold-tinted inductor; 5-conditioning controller.
Embodiment
In order to deepen the understanding of the present invention, below in conjunction with embodiment and accompanying drawing, the invention will be further described, and this embodiment only, for explaining the present invention, does not form limiting the scope of the present invention.
Fig. 1 shows a kind of a kind of execution mode that strengthens the decode system of machine visual contrast of the present invention, comprise decoding device body 1, in described decoding device body 1, decoder 2 is installed, camera head 3 and radiation source 4, described decoder 2 is connected with camera head 3 by data wire, the three primary colors light source that described radiation source 4 is changeable monochromatic source, described radiation source 4 also connects one for regulating the conditioning controller 5 of toggle lights output, the front end of described radiation source 4 is also respectively equipped with and is connected with ruddiness inductor 41, blue light inductor 42 and gold-tinted inductor 43, in the process of decoding, according to the Quick Response Code of different background colors, ruddiness inductor 41, after blue light inductor 42 and gold-tinted inductor 43 sense, pass the signal to conditioning controller 4, conditioning controller 4 is according to corresponding signal, adjust the output light source color of radiation source 4, thereby camera head can photograph the two-dimension code image that contrast is relatively strong, and decode by decoder 2, thereby increased the decoding accuracy of decoding device, also improved the applicability of decoding device.
