Description
Technical field
This utility model relates to the method and apparatus that machine-readable character is decoded, and relates more particularly to
A kind of scanning device.
Background technology
Machine-readable character（MRS）There is provided a kind of to being in compact printing form（Or emersion form）Information（It is permissible
It is scanned and and then by based on the translation of optical symbol detector）The mode being encoded.Such machine-readable character
Often it is attached to（Or be stamped in）Product packaging, food product, general article of consumption, machine parts, equipment and other system
Make the purpose for the identification based on machine and tracking in project.
One exemplary types of machine-readable character are bar codes, and it adopts a series of along single file vertical orientation
And white space.Groups of bar and space correspond to code word.Code word and alpha-numeric characters, one or more digit order number
Several or other mark functions are associated.
For the ease of greater amount of information is encoded into individual machine readable symbol, have been designed that two dimension（2D）Bar
Shape code.These are also generally referred to as stacking, matrix and/or area barcode（area bar code）.2D matrix notation adopts
The unit of regular polygon（Also referred to as element or module）Arrangement, typically square.Unit in 2D matrix notation
Specific arrangements represent data characteristic and/or mark function.
In the document, interchangeably term " bar code " and " symbol " are adopted, both generally refer to machine-readable character, no
By being linear or two dimension.
Symbol reader using also referred to as scanning device（Or bar code reader）Come using various optics
Scan electronics and method read matrix notation.In order to suitably scan symbol, this symbol must the visual field of reader it
Interior.Some readers are hand-held, and can aim at symbol；Other readers are fixed on position, and symbol（And
The object arriving accompanying by symbol）It is necessarily placed within the visual field of reader.
No matter which kind of mode, symbol scanning device can project " sight pattern " or " sight beam "（The pattern of light, its
The scanner center of visual field can be indicated）；Sight pattern can also project/include turning pattern to indicate the edge of visual field.
The sight pattern being projected and aiming symbol be properly aligned with or overlapping instruction scanning device is suitably aimed to be scanned.
Once scanning device and symbol are properly aimed so that call sign is in the visual field of scanning device, scanning device is just via one-tenth
Element carries out image capturing.When image-forming component captures glyph image, generally it is necessary for closing sight beam, because right
For imager, sight pattern is visible and becomes the noise being superimposed upon on symbol.Even if concentrating on particular color（Red
Color, amber, green）, existing sight also all has high intensity on the sensitive wavelength of imageing sensor.Therefore, hold
Easily capture the sight illumination of symbol, it can upset symbolic interpretation.In other words, when sight is connected, imager is not
The image of symbol can reliably be captured.Great majority are usually used there is the imageing sensor of electronic scroll shutter for, this
It is correct.Therefore, in sight " on "（Illuminate symbol）In the case of time of being spent directly reduce imager bar shaped
Code reader response speed.
Alternatively, for global shutter imageing sensor, the response speed of reduction may be less problem, because
Sight can be connected during whole image captures the shutter close part in cycle.But for global shutter imageing sensor
For, short circuit lead to the period sight also as the restriction of sight light source output power and become less visible.On and off
（on-and-off）Sight also introduces flash mode, and this causes eyestrain of user.
Solve this problem a kind of method be using total image illumination had less contribution be continuously turned on aim at
Device；Such as sight pattern can be thin or have a ray mode.However, for having high density, difference printing quality
2D symbol or there is relatively low redundancy rate 2D code for, this balance be introduced into difference decoding rate.
Accordingly, there exist the Gao Shui that is shared but still realizes with symbol decoding the time avoiding between aiming process and symbol capture
Put down the needs illuminating both system and method for sight illumination and symbol capture of accurate performance.
Utility model content
Therefore, in an aspect, this utility model uses the light of different colours（I.e. different frequency or different frequency bands）Come
Sight pattern is made to separate with image capturing illumination bandwidth.This enables call sign scanning device to capture glyph image, even if taking aim at
When quasi- device light is always turned on.In one embodiment, sight mould can be stoped by adding color barrier filters
Formula reaches imageing sensor to realize color separated.But imageing sensor becomes to be achromatopsia effectively for sight color
's.Image using the capture of this kind equipment is not to be subject to sight schema constraint（aimer pattern free）.
Alternatively, color separated can also process in fact via software image using the color image sensor being usually used
Existing it is not necessary to color barrier filters.However, software Algorithm for Color Image Filtering can lead to some degradations of picture quality；May
Reduce decoding performance；May introduce the longer decoding time；Or the processor cost that may make increase necessitates.
Some in the advantage of color separated sight can include：
Sight pattern can be full frame, thus indicating visual field（FOV）, centre mark and nearly center optimum solution
The whole frame in code area；
Sight pattern can also include some cue marks, such as decoded state（For example get out triggering, be busy with
Decode, be successfully decoded or decode failure）；

Light 118, this reading light 118 includes at least second band different from the first band from sight 222.1.
In a step 715, the light that symbol reader reception is reflected back from machine-readable character.
In the first embodiment, symbol reader has and is configured to the light of the light to second frequency rather than first frequency and enters
The imaging sensor 232 of row response.Continue from step 715, in step 720.1, the imageing sensor 232 being so configured is raw
Become to represent the light of second frequency and be suitable for the signal of telecommunication of symbol data determination.In step 735, symbol reader 100 basis
The signal of telecommunication is determining symbol data.
In the second embodiment of a replacement, symbol reader has imaging sensor 232, and it can be to first frequency
Light and the light of second frequency responded.Continue from step 715, in step 720.2, by being configured to make second
The light of frequency by and stop that the light filter of light of first frequency processes the light receiving of reflection.In step 725.2, warp
The light of filtering is received by imageing sensor 232, and then it generate the light representing second frequency and determine with being suitable for symbol data
The signal of telecommunication.In step 735, symbol reader 100 determines symbol data according to this signal of telecommunication.
In the 3rd embodiment substituting, symbol reader has can be to the light two of the light of first frequency and second frequency
The imaging sensor 232 that person is responded.Continue from step 715, in step 720.3, imageing sensor is in response to the first frequency
Band and second band and generate the signal of telecommunication, thus generate reflection two frequency bands the signal of telecommunication.In step 725.3, symbol
Reader 100 in the way of digital to signal of telecommunication filtering to select to indicate the signal element of second band, remove instruction the simultaneously
The element of one frequency band.In step 735, symbol reader 100 determines symbol data according to the signal of telecommunication.
Summarize.
Exemplary symbols reader 100 to illuminate machine-readable character using at least two detached colors or frequency band.The
One frequency band is used to illuminate symbol to help aim at reader.Second frequency is utilized for actually reading symbol and providing shining
Bright.By using two detached frequency bands, in the case of so that signal integrity is degraded and do not reducing symbol reading process
Reliability in the case of, aim at symbol reader 100 and read machine readable symbol 102 thus be engaged in two operations simultaneously
It is possible.
