Description

具有颜色分离的瞄准器和照明器的成像条形码阅读器 Sight and having a color separation imaging illuminator bar code reader

技术领域 FIELD

[0001] 本发明涉及用于对机器可读符号进行解码的方法和装置,并且更特别地涉及用于瞄准符号阅读器并照亮机器可读符号的方法和装置。 [0001] The present invention relates to a method and apparatus for machine-readable symbol for decoding, and more particularly relates to an aiming symbol reader illuminates the machine-readable symbol and a method and apparatus.

背景技术 Background technique

[0002] 机器可读符号(MRS)提供一种对处于紧凑印刷形式(或浮出形式)的信息(其可以被扫描并且然后通过基于光学的符号检测器翻译)进行编码的方式。 [0002] The machine-readable symbol (MRS) to provide a compact information in printed form (form or float) (which can be scanned and then translated by the symbol based on the optical detector) coding. 这样的机器可读符号经常被附着到(或压印在)产品包装、食物产品、一般消费项目、机器零件、设备以及其它制造项目上以用于基于机器的识别和跟踪的目的。 Such machine-readable symbol is often attached to (or embossed) on the product packaging, food products, consumer items in general, machine parts, manufacturing equipment, and other items for the purpose of identifying and tracking the machine.

[0003] 机器可读符号的一个示例性类型是条形码,其采用沿着单行垂直定向的一系列条和白色空间。 [0003] One exemplary type of machine readable symbol is a bar code, which uses a series of bars and white spaces along a single line perpendicular orientation. 成组的条和空间对应于代码字。 Groups of bars and spaces correspond to the code word. 代码字与字母-数字符号、一个或多个数字位数或其它符号功能相关联。 Code word letters - numeric symbols, one or more digits or other symbols associated functions.

[0004] 为了便于将更大数量的信息编码成单个机器可读符号,已经设计出了二维(2D)条形码。 [0004] In order to facilitate a greater number of machine-readable information is encoded into a single symbol, have been designed two-dimensional (2D) bar codes. 这些通常也被称为堆叠的、矩阵和/或区域条形码(area bar cockOJD矩阵符号采用规则多边形形状的单元(也被称为元素或模块)的布置,通常是正方形。2D矩阵符号中单元的特定布置表示数据特性和/或符号功能。 The arrangement also commonly referred to as stacked, matrix and / or the barcode area (area bar cockOJD using matrix notation of a regular polygon shaped cells (also referred to as an element or a module), typically specific square matrix notation unit .2D arrangement data indicative of characteristics and / or symbols function.

[0005] 在本文档中,互换地采用术语“条形码”和“符号”,两者通常指代机器可读符号,无论是线性的还是二维的。 [0005] In the present document, the term interchangeably "bar code" and "symbol", generally refers to both the machine-readable symbol, either linear or two-dimensional.

[0006] 采用也被称为扫描器的符号阅读器(或者条形码阅读器)来使用各种各样的光学扫描电子器件和方法读取矩阵符号。 [0006] The symbol reader is also referred to as a scanner (or bar code reader) to use various optical scanning method of an electronic device and reading the matrix symbol. 为了适当地扫描符号,该符号必须在阅读器的视场之内。 In order to properly scan the symbol, the symbol must be within the field of view of the reader. 一些阅读器是手持的,并且可以瞄准符号;其它阅读器被固定在位置上,并且符号(以及符号所附着到的对象)必须被放置在阅读器的视场之内。 Some hand-held reader, and you can target symbol; other reader is fixed in position, and the symbol (and the symbol attached to the object) to be placed within the field of view of the reader.

[0007] 无论哪种方式,符号扫描器可以投射“瞄准器模式”或“瞄准器射束”(光的模式,其可以指示视场的扫描器中心);瞄准器模式还可以投射/包括拐角模式以指示视场的边缘。 [0007] Either way, the scanner can be projected symbol "sight mode" or "sight beam" (mode of light, which may indicate the center of the scanner field of view); sight mode may also projecting / corners include mode to indicate the edge of the field of view. 所投射的瞄准器模式与目标符号的适当对准或重叠指示扫描器被适当地瞄准以进行扫描。 Proper alignment of the projected pattern of the target sight or overlapping symbol instructs the scanner is properly aimed to scan.

[0008] —旦扫描器和符号被适当地对准以使得符号在扫描器的视场中,扫描器就经由成像元件进行图像捕获。 [0008] - Once the scanner and symbols are properly aligned so that the field of view of the scanner at the symbol, the scanner proceeds via the image capturing of the imaging element. 当成像元件捕获到符号图像时,通常就必须关闭瞄准器射束,因为对成像器而言瞄准器模式是可见的并且变成叠加在符号上的噪声。 When the imaging element is image captured symbol, usually sight beam must be shut down, as for the imager is visible sight mode and becomes noise superposed on the symbols. 即使集中于特定颜色(红色、琥珀色、绿色),现有的瞄准器也都在图像传感器所敏感的波长上具有高强度。 Even concentrated on a specific color (red, amber, green), conventional sight also has high strength on the image sensor is sensitive to the wavelength. 因此,容易捕获到符号的瞄准器照明,其可以扰乱符号解释。 Thus, to easily capture sight symbol illumination, which may disturb sign explained. 换句话说,当瞄准器接通时,成像器不能可靠地捕获符号的图像。 In other words, when the sight is turned on, the imaging can not reliably capture the image of the symbol. 对大多数通常使用的具有电子滚动快门的图像传感器来说,这是正确的。 For most image sensor with an electronic rolling shutter is commonly used, this is correct. 因此,在瞄准器“接通”(照亮符号)的情况下所花费的时间直接降低成像器条形码阅读器响应速度。 Therefore, the time in the case of sight "ON" (illuminated symbol) takes imager directly reduce the response speed of the bar code reader.

[0009] 作为替代,对于全域快门图像传感器来说,降低的响应速度可能更不是问题,因为瞄准器可以在整个图像捕获周期的快门关闭部分期间接通。 [0009] Alternatively, the image sensor for the global shutter, the response speed may be lowered is not a problem, since the sight can be turned off during a portion of the entire image-capturing period of the shutter is turned on. 但是对于全域快门图像传感器来说,短接通时段的瞄准器还因为瞄准器光源输出功率的限制而变得更不可见。 But for the global shutter image sensors, but also because of the limitation of short aimer light source output power becomes less visible sight ON period. 通和断(on-and-off)瞄准器还引入闪光模式,这引发用户的眼睛疲劳。 On and off (on-and-off) is also introduced into the flash mode sight, which led to the user's eye fatigue.

[0010] 解决这一问题的一种方法是使用对总的图像照明具有更少贡献的持续接通瞄准器;例如瞄准器模式可以是薄的或者具有点线模式。 A method [0010] The solution to this problem is to use continues to be on sight having less contribution to the total image illumination; e.g. sight mode may be a thin line or a dot pattern. 然而,对于具有高密度、差印刷质量的2D符号或具有较低冗余率的2D代码来说,这个权衡将引入差的解码率。 However, for a high-density, poorly printed symbols 2D or 2D codes having lower redundancy rates, this tradeoff introducing decoding rate difference.

[0011] 因此,存在对避免瞄准过程和符号捕获之间的时间共享但仍实现符号解码的高水平准确性能的用于瞄准器照明和符号捕获照明两者的系统和方法的需要。 [0011] Accordingly, there is aimed at avoiding the time between the process and the shared symbol capturing still achieving high levels of performance accuracy required for symbol decoding system and method of both lighting and sight symbol capturing illumination.

发明内容 SUMMARY

[0012] 因此,在一个方面中,本发明使用不同颜色的光(即不同频率或不同频带)来使瞄准器模式与图像捕获照明带宽分开。 [0012] Accordingly, in one aspect, the present invention is the use of different colors of light (i.e., different frequencies or different frequency bands) to make the sight is separated from the image capturing mode illumination bandwidth. 这使得符号扫描器能够捕获符号图像,即使在瞄准器光总是接通的时候。 This scanner capable of capturing a symbol so that the symbol image, even when the aimer light is always turned on. 在一个实施例中,可以通过添加颜色阻挡滤波器来阻止瞄准器模式到达图像传感器来实现颜色分离。 In one embodiment, it is possible to prevent the pattern reaching an image sensor sight the color separation achieved by the addition of a color filter barrier. 然而图像传感器变得对瞄准器颜色来说是有效地色盲的。 However, the color image sensor becomes of sight is effectively color blind. 使用此类设备捕获的图像是不受目苗准器模式约束的(aimer pattern free)。 Use of such devices is not an image captured mesh pattern seedling aligner constraints (aimer pattern free).

[0013] 替代地,颜色分离还可以利用通常使用的颜色图像传感器经由软件图像处理来实现,不需要颜色阻挡滤波器。 [0013] Alternatively, the color separation can also use a color image sensor used typically implemented via software image processing, the color does not require blocking filter. 然而,软件彩色图像滤波可以导致图像质量的一些降级;可能降低解码性能;可能引入更长的解码时间;或者可能使增加的处理器成本成为必要。 However, the color image software filtering can cause some image quality degraded; decoding performance may be reduced; may introduce a longer decoding time; or may cause the cost of increased processor becomes necessary.

[0014] 颜色分离瞄准器的优点中的一些可以包括: •瞄准器模式可以是全帧的,从而指示视场(F0V)、中心标记、以及近中心最佳解码区的整帧; •瞄准器模式还可以包括一些指示标记,诸如解码状态(例如准备好触发、忙于解码、 成功解码或解码失败); •瞄准器模式还可以可能地指示解码状况,诸如对于解码来说太远或者太近。 Advantage of [0014] color separation sight some of which may include: • sight mode may be a full frame, indicating that a full frame field of view (F0V), central mark, and the best decoding region near the center; • sight mode may also include some indicator, such as decoding status (eg ready to trigger, decode busy, successful decoding or decoding failure); • sight mode also may indicate decoding conditions, such as the decoding is too far away or too close.

[0025] 这里提供的标题仅为了方便起见并且不解释要求保护的发明的范围或含义。 [0025] The headings provided herein are for convenience only and do not interpret the scope or meaning of the claimed invention.

[0026] 颜色、频率和频带。 [0026] color, and frequency band.

[0027] 遍及下面的讨论,将理解的是,对“颜色”、“光的颜色”或“光的频率”的引用(不论是对“颜色”的普遍引用还是对特定颜色(诸如蓝色、红色、黄色等等)的引用)可以不仅指代单个频率。 [0027] throughout the following discussion, it will be appreciated that, for the "color", "color of light" or "frequency of the light 'references (both for the" color "is generally a reference to a particular color (such as blue, reference red, yellow, etc.)) can refer to only a single frequency. 替代地,对第一颜色或第一频率的这种引用可能指代要与处于第二频带的第二颜色区分开(例如经由滤光器)的适当缩小的频带。 Alternatively, reference may be appropriately reduced to refer region separated from the second color in a second frequency band (e.g., via filter) of such first color band or first frequency. 所以例如,“红色”可能指代与人类所感知的红颜色相关联的频率范围(大概405THz到480THz),并且它可以与其它颜色(诸如蓝色(大概610到665THz)或黄色(大概510到540THz)等等)区分开。 Therefore, for example, "red" may refer to the human perceived frequency range associated with the red color (presumably 405THz to 480THz), and it may be other colors (such as blue (about 610 to 665THz) or yellow (about 510 to separate 540THz), etc.) area.

[0028] 颜色可以指代按照惯例归因于特定颜色的整个频率范围,或者该范围的一个或多个子集,并且理解实际所选择的特定频率范围将适合于指定的应用(诸如对2D符号进行成像)。 [0028] Color may refer to (such as the application of the 2D symbols conventionally designated the entire frequency range due to the specific color or the range of one or more subsets, a particular frequency range and appreciated that the actual selection will be suitable imaging). 在不同实施例中,可以采用常见频率范围内的不同频率范围(例如,“绿色光谱”内的不同频带)。 In various embodiments, different frequency ranges can be employed (e.g., different frequency bands within the "green spectral") within a common frequency range. 在实际应用中,光的投射频率或光的接收频率可以少量地延伸到邻近颜色的频带中;或者投射的光可能具有多个频带,但是具有强度上占优势的指定频率或频带,到达使得所投射的光对一个优势频带有效的程度。 In practice, the projection of light received frequency or frequency of the light may extend a small amount into the color of the adjacent bands; projected light or may have a plurality of bands, but with a specified frequency or frequency band on the dominant intensity, so that the arrival one advantage of projected light to an extent effective band.

[0029] 还要理解的是,在实际应用中,指定频带可以与两个或者甚至三个常见颜色的域(domain)重叠(例如,指定频带可以包括绿色和黄色频带的相邻部分)。 [0029] It is also understood that, in practice, the specific frequency band may be two or even three common color domain (Domain) overlap (e.g., may comprise a designated frequency band adjacent portions of green and yellow bands).

[0030] 如本文所使用的术语“宽带”指代基本上跨越常用颜色(例如从红色到绿色,或者黄色到蓝色)的全部多个频带的光发射,其中在强度上没有一个频带实质上占优势。 [0030] As used herein the term "broadband" refers to a substantially across common color (e.g. from red to green, or blue to yellow) all of the plurality of light emitting bands, wherein a frequency band is substantially no strength in dominant. “宽带” 还可以指代不相邻的多个频带的发射,但是通常包括多个不同按常规命名的颜色。 "Broadband" may also refer to a plurality of emission bands are not adjacent generations, but typically comprising a plurality of different conventional color naming. “宽带” 还可以指代白色的光发射,也就是说基本上跨越所有可见颜色(红色到蓝色)。 "Broadband" may also refer to a white light emission, i.e. substantially across all visible colors (red to blue). 通常,术语“频带”或“颜色”可以被理解为频率范围上的显著更窄,并且与宽带发射可区分开。 Generally, the term "band" or "color" may be understood to significantly narrower frequency range, and can be separated from the broadband emitter region.

[0031] 在许多情况下,在本文档中,没有指定特定颜色,并且更确切地说参考第一频带或第二频带;将理解的是在特定实施例中,可以为每个频带指派适合于眼前的应用的特定分离的颜色。 [0031] In many cases, this document does not specify a specific color, and more specifically with reference to the first band or the second frequency band; will be understood that in particular embodiments, can be adapted to the frequency band assigned to each in front of a specific color separation applications.

[0032] 还将理解,尽管在本文中主要对“颜色”、“频率或光”或者“频带”进行引用,但是可以容易地就光的波长来进行这样的描述。 [0032] will also be appreciated that although primarily on the "color", "frequency or optical" or "band" referenced herein, but may be easily performed on the wavelength of the light to such description. 仅为了方便而选择“颜色”或“频率”。 Convenience only select the "Color" or "frequency." 通常,在本文档中,可互换地采用“颜色”、“各颜色”和“频率“或”各频率“。 Typically, in this document, employed interchangeably, "Color", "each color" and "frequency" or "the respective frequencies."

[0033] 例如仅在这里列出(并且没有限制)的是可以按照惯例被指派到各种可见颜色的频率范围中的一些: 红色:大概405到480THz或者700到625nm; 橙色:大概480到510THz或者625到590nm; 琥珀色:在橙色和黄色的边界处被不同地指派,但是通常中心在大概504THz或595nm; 黄色:大概510到540THz或者590到560nm; 绿色:大概540到580THz或者560到520nm; 青色:大概580到6IOTHz或者520到495nm; 蓝色:大概610到665THz或者495到450nm; 紫色:大概665到790THz或者450到380nm。 [0033] In the example listed here only (and without limitation) that can be assigned to the various colors of the visible frequency range of some conventionally: Red: 700, or about 405 to 625nm to 480THz; orange: about 480 to 510THz or 625 to 590 nm; amber: differently assigned boundary yellow and orange, but generally in the center or approximately 595 nm 504THz; yellow: about 510 to 590 or of 560 nm to 540THz; green: 560 or about 540 to 520nm to 580THz ; cyan: about 580 or 520 to 495nm to 6IOTHz; blue: about 610 to 495 or of 450 nm to 665THz; purple: 450 or about 665 to 790THz to 380nm.

[0034] 本领域技术人员将认识到在常用颜色之间具体划分的频率或划分的波长必然有点随意,并且在来自不同源的描述中可以稍稍变化。 [0034] Those skilled in the art will recognize that the frequency or wavelength division between common colors specific division necessity somewhat arbitrary, and may vary slightly from different sources are described.

[0045] 在本系统和方法的一个实施例中,符号阅读器100可以是光学阅读器。 [0045] In one embodiment of the present system and method, the symbol reader 100 may be an optical reader. 光学阅读器100可以包括用于照亮目标对象T的照明组件220,其使ID或2D条形码符号102附着或压印在其上。 The optical reader 100 may include an illumination assembly for illuminating a target object T 220, which changes the ID or 2D bar code symbol 102 is attached or imprinted thereon. 光学阅读器100还可以包括成像组件230,其用于接收对象T的图像并且生成指示被光学编码在其中的数据的电输出信号。 The optical reader 100 may further include an imaging assembly 230 for receiving an image of an object T and generating an electrical output signal indicative of the data optically encoded therein.

[0047] 在实施例中,第一分离光(激光器或LED)222.1被用来产生瞄准器光116,而第二分离照明光(通常LED,但是可以是激光器)222.2被用来产生读取光118以支持成像组件230读取符号102。 [0047] In an embodiment, the first separating light (laser or LED) 222.1 sight is used to produce light 116, and the second separating illumination light (typically the LED, but may be a laser) is used to produce 222.2 reading light 118 to support the imaging assembly 230 reads the symbol 102. 在一个替代实施例中,瞄准器LED/激光器222.1和照明LED 222.2可以被组合成单个照明元件。 In an alternative embodiment, the sight LED / laser illumination LED 222.2 and 222.1 may be combined into a single illuminating element.

[0048] 在一个实施例中,提供分离的瞄准光学器件224.1和照明光学器件224.2。 [0048] In one embodiment, there is provided an isolated sighting optics illumination optics 224.1 and 224.2. 在一个替代实施例中,单个光学元件或光学元件组可以提供用于瞄准和照明两者的聚焦。 In an alternative embodiment, a single optical element or the optical element group may be provided for both the focusing and aiming illumination.

[0049] 成像组件230接收从符号102反射的反射光260。 [0049] The reflective imaging assembly 230 receives light 102 reflected from the symbol 260. 反射光260可以包括目苗准器光116、 照明光118、或者两者的光谱分量。 Reflected light 260 may include a light 116, the illumination light 118, or both of the spectral components of the seedling aligner mesh. 在一个实施例中,成像组件230可以包括图像传感器232 (诸如2D CCD或CMOS固态图像传感器),连同用于接收对象T的图像并将其聚焦到图像传感器232上的成像光学组件234。 In one embodiment, the imaging assembly 230 may include an image sensor 232 (such as a 2D CCD or a CMOS solid-state image sensor), with the image receiving object for T and focuses it on the image forming optical assembly 234 of the image sensor 232. 成像组件230的视场将取决于应用。 Field of view of the imaging assembly 230 will depend on the application. 一般来说,视场应该足够大以使得成像组件可以捕获包括在靠近读取范围的图像数据读取区域的场景的位图表示。 In general, the field of view should be large enough so that the imaging assembly to capture bitmap includes data reading region in the image reading range near the representation of the scene. [0050]在本系统和方法的一个实施例中,图2的示例性符号阅读器100还包括可编程控制器240,其可以包括集成电路微处理器242和专用集成电路(ASIC)244。 [0050] In one embodiment of the present system and method, an exemplary symbol reader 2 100 further includes a programmable controller 240, which may include a microprocessor 242 and ASIC integrated circuit (ASIC) 244. 处理器242和ASIC 244两者是可编程控制设备,其能够根据存储在读取/写入随机存取存储器(RAM)245和可擦除只读存储器(ER0M)246中的任一个或二者中的存储程序来接收、输出和处理数据。 Both ASIC 242 and processor 244 is a programmable control device, which can be stored in accordance with the read / write random access memory (RAM) 245, and EEPROM (ER0M) 246 in either or both of the stored program to receive, process and output data. 处理器242和ASIC 244二者还被连接到通用总线248,可以通过该通用总线248来在也连接到其的任何电路的任一方向上接收和发射程序数据和工作数据(包括地址数据)。 Both processor 242 and the ASIC 244 is further connected to the common bus 248 can receive and transmit program data and working data (including address data) by either one of the 248 is also connected to any circuit of the general-purpose bus which upwardly. 然而,在如何制造它们和如何使用它们方面,处理器242和ASIC 244可以彼此不同。 However, how to make and how to use them aspect thereof, ASIC 244 and processor 242 may be different from each other.

[0051 ] 在一个实施例中,处理器242可以是通用,现成(off-the-shelf)VLSI集成电路微处理器,其具有对图2的电路的全面控制,但是将其大部分时间致力于根据存储在EROM 246 中的程序数据来解码存储在RAM 245中的图像数据。 [0051] In one embodiment, the processor 242 may be a general shelf (off-the-shelf) VLSI integrated circuit microprocessor which has overall control of the circuit of Figure 2, it will be time to devote most of its decoding image data stored in the RAM 245 in accordance with program data stored in EROM 246. 另一方面,处理器244可以是专用VLSI 集成电路(诸如可编程逻辑或门阵列),其被编程为将其时间致力于不同于解码图像数据的功能,并且因此解除了处理器242的执行这些功能的负担。 On the other hand, processor 244 may be a dedicated VLSI integrated circuit (such as a programmable logic or gate array), which is programmed to its commitment time function is different from the decoded image data, and the execution processor 242 thus releasing these burden functionality.

[0052] 在替代实施例中,如果通用处理器242足够快速且足够强大到执行本系统和方法所设想的所有功能,则可以完全消除专用ASIC 244。 [0052] In an alternative embodiment, if the general purpose processor 242 fast enough and powerful enough to perform all the functions of the systems and methods contemplated, it can be completely eliminated dedicated ASIC 244. 因此,将理解到所使用的处理器的数目、它们之间的工作的划分都不具有针对本系统和方法的目的的任何基本意义。 Thus, it will be appreciated the number of processors to be used, the division of work between them do not have any fundamental significance for purposes of the present system and method.

[0053] 在一个实施例中,示例性符号阅读器100包括信号处理器235和模拟到数字(A/D) 芯片236。 [0053] In one embodiment, an exemplary symbol reader 100 includes a signal processor 235 and an analog to digital (A / D) 236 chips. 这些芯片一起从图像传感器232得到原始数据并且将数据转换成数字格式,在一个示例性实施例中其可以是用于由可编程控制器240进一步处理的传达特定颜色或颜色带宽的数字格式。 These chips together to obtain the raw data from the image sensor 232 and converts the data into digital format, in one exemplary embodiment which may be used to convey a particular color or color bandwidth controller 240 for further processing by the programmable digital format.

[0054] 在一个实施例中,本发明的系统和方法采用存储在EROM 246中的算法,其使得可编程控制器240能够分析来自信号处理器235和A/D 236的图像数据。 [0054] In one embodiment, the system and method of the present invention employs an algorithm stored in EROM 246 in which such a programmable controller 240 can analyze the image data from the signal processor 235 and A / D 236 is. 在一个实施例中并且如下文进一步描述的,此图像分析可以包括分析图像数据中的颜色或频率信息(不同频带的级别)。 In this embodiment and as further described an embodiment, the image analysis may include color or frequency information (level different frequency bands) Analysis of the image data. 在一个实施例中,并且部分基于颜色分析,可编程控制器240然后可以实施改进系统和方法来将由瞄准器222.1(或瞄准器滤波器320.1,参见图3)提供的第一颜色和由照明器222.2(或照明器滤波器320.2,参见图3)提供的第二颜色区分开。 In one embodiment, and in part based on color analysis, the programmable controller 240 may then implement an improved system and method by sight 222.1 (320.1 filters or sight, see FIG. 3) and a first color provided by the illuminator 222.2 (320.2 or illumination filter, see FIG. 3) provided separately from the second color region.

[0055] 示例性符号阅读器100还可以包括例如支持键盘112和触发器114的使用的输入/ 输出(I/O)电路237。 [0055] Exemplary symbol reader 100 may further comprise, for example, support the use of the keyboard 112 and the flip-flop 114 input / output (I / O) circuit 237. 符号阅读器100还可以包括支持显示器110的输出/显示电路238。 Symbol reader 100 may further include an output display 110 of the support / display circuit 238.

[0056] 在瞄准器和照明器之间具有颜色区别的示例性符号阅读器、以及颜色选择图像传感器。 [0056] Exemplary symbol reader has a color difference between the sight and the illumination device, an image sensor and a color selection.

[0057] 在常规符号阅读器100中,光源222(例如瞄准器LED 222.1和照明LED 222.2,不管实际上是两个物理元件还是仅一个物理元件)可以采用:(i)光的常见颜色或频率,或者(ii)两个光谱带之间没有分离的两个相似的颜色或频率(例如部分重叠的频带)。 [0057] In the conventional symbol reader 100, light source 222 (e.g., LED 222.1 sight and lighting LED 222.2, regardless of the physical components actually two or just one physical element) may be employed: a common color (i) of light or frequency or (ii) there is no separation between the two spectral bands of two colors or similar frequency (e.g. partially overlapping frequency bands). 这可能导致投射用于瞄准阅读器100的瞄准器光116和投射用于光学地获得符号102的目的的照明光118之间的干扰问题。 This may cause the projection 100 for aiming sight of the reader and the projection light 116 for optically obtaining interference between symbols 102 118 object illumination light. 现有技术的符号阅读器已经以本文档中上文描述的方式解决了导致各种性能妥协的这些干扰问题。 Art symbol reader has solved these problems led to interference of various performance compromise in the manner described in this document above.

[0058] 本系统和方法引入对使用至少两种不同颜色或等同地至少两个不同频带的使用, 其中为瞄准器光116指定至少一个这样的频带并且为照明光118指定另一个这样的频带。 [0058] The present system and method for introducing at least two different colors or at least two different frequency bands equivalently, wherein the optical sight 116 is specified and at least one of such bands such as band 118 specify another illumination light. 将要理解的是,分别针对瞄准和图像获取所采用的不同频带中的至少两个将基本上不重叠。 It will be understood that each acquire at least two different frequency bands will not overlap substantially used for targeting and the image. 在不同实施例中,优选的颜色频率可以改变。 In various embodiments, the preferred frequency may change color.

[0059] 本系统和方法的第一示例性实施例可以采用单色图像传感器232、蓝色瞄准器LED 222.1、 以及所谓的“白色”照明LED 222.2(其主要地以光谱的蓝色和黄色部分投射)。 [0059] The first exemplary embodiment of the present system and method may employ a monochrome image sensor 232, sight blue LED 222.1, and so-called "white" illumination LED 222.2 (which is primarily blue and yellow part of the spectrum projection). 此组合可以有效地区分成像光118和瞄准器光116,因为单色图像传感器232可以具有对蓝色频率的相对弱的响应。 This combination may be divided into effective image light region 118 and the optical sight 116 as monochrome image sensor 232 may have a relatively weak blue frequency response. 因此,成像光118中的黄色频率将在影响成像传感器232方面占优势,并且因此在对符号102进行成像方面占优势;而蓝光(无论来自瞄准器LED 222.1还是照明LED 222.2)将在成像过程中引入相对少的干扰。 Thus, the yellow light 118 in the imaging frequency will affect the image sensor 232 in terms of the dominant, and therefore in terms of dominant symbols 102 imaging; Blu-ray (whether from sight or LED 222.1 lighting LED 222.2) in the imaging procedure introducing relatively little interference.

[0060] 本系统和方法的第二示例性实施例可以采用单色图像传感器232、蓝色瞄准器LED 222.1、 以及红色或琥珀色(大概504THz或595nm)照明LED 222.2。 [0060] The second exemplary embodiment of the present system and method may employ a monochrome image sensor 232, sight blue LED 222.1, and a red or amber (about 595 nm or 504THz) illumination LED 222.2. 此组合可以避免对成像组件230中的滤色器330的需要(参见下面的图3)。 This avoids the need for a combination of imaging assembly 230, a color filter 330 (see FIG. 3 below).

[0061] 本系统和方法的第三示例性实施例可以采用颜色图像传感器232、琥珀色或青色瞄准器LED 222.1和具有不同于琥珀色或青色的颜色的显著光谱强度的照明LED 222.2或宽带照明LED 222.2。 [0061] The third exemplary embodiment of the present systems and methods may employ a color image sensor 232, amber or cyan LED 222.1 sight and significantly different from the spectral intensity of the color of amber or cyan or broadband illumination lighting LED 222.2 LED 222.2. 此组合可以有效地区分成像光118和瞄准器光116,因为颜色图像传感器232可能对与琥珀色或青色相关联的频率具有相对弱的响应。 This combination may be divided into effective image light region 118 and the optical sight 116, because the color image sensor 232 may have a relatively poor frequency response of amber or cyan associated.

[0062] 本系统和方法的第四示例性实施例采用软件滤色。 [0062] The fourth exemplary embodiment of the present system and method using software filter. 这样的实施例可以使用针对瞄准器LED 222.1的第一指定颜色;针对照明LED 222.2的至少一个第二指定颜色(在与第一个不同的频带中);以及从由成像组件230产生的信号去除第一指定颜色(瞄准器颜色)的软件图像/颜色处理。 Such embodiments may be used to specify a color for the first sight of LED 222.1; for at least a second specified color of the illumination of LED 222.2 (at a different frequency band from the first); and removing from the signal generated by the imaging assembly 230 a first designated color (color sight) software image / color processing.

[0063] 此第四示例性实施例可以需要下面的阶段:(i)将来自成像组件230的模拟图像信号转换成数字形式;(ii)对经数字化的信号执行傅立叶分析或类似分析以识别特定频率元素;以及(iii)去除与第一指定颜色相关联的频率元素。 [0063] This fourth exemplary embodiment may require the following stages: (i) converting the analog image signal from the imaging assembly 230 into digital form; (ii) the signal performs the digitized Fourier analysis or similar analysis to identify a particular frequency element; and (iii) removing the elements of the first frequency associated with the specified color.

[0064] 第四示例性实施例(软件滤色器方法)的可能成本可以包括:(i)图像质量的一些降级,其可能降低解码性能;(ii)彩色图像滤波可以增加解码时间;以及(iii)可能需要更昂贵的硬件处理器240。 [0064] The fourth exemplary embodiment (software filter method) may be cost comprises: downgrading some of (i) image quality, which may reduce the performance of decoding; (ii) a color image filtering may increase decoding time; and ( iii) may require more expensive hardware processor 240. 下面在本文档中进一步讨论软件滤波器方法的一些可能的优点。 Discussed further below some of the possible advantages of the software filter approach in this document.

[0065] 上面的实施例仅是示例性的。 [0065] The above embodiments are merely exemplary. 由LED瞄准器222.1投射的一个或多个第一颜色、由照明LED 222.2投射的一个或多个第二光谱上不同的颜色、以及由图像传感器232的其它可能光谱响应的其它组合都可以在本系统和方法的范围和精神之内被预见,如在所附权利要求中记载的那样。 222.1 sight projected by the LED one or more first color, a second or a plurality of spectrally distinct colors 222.2 projected by the illumination LED, and the other may be other combinations of the spectral response of the image sensor 232 may be present in the It is foreseen within the scope and spirit of the systems and methods, as described in the appended claims.

[0066] 在本系统和方法的各种实施例中,瞄准器光谱和照明光谱具有至少一种常用颜色或一个常用光谱带,连同在这两个之间有区别的一种或多种无论什么颜色。 [0066] In various embodiments of the present system and method embodiments, the spectrum and the spectrum of lighting sight having at least one common color or common spectral band, together with a difference between the two, one or more whatever colour. 在一个替代实施例中,(多个)瞄准器颜色和(多个)照明颜色基本上彼此有区别,也就是说它们不具有实质性的光谱重叠。 In an alternative embodiment, (s) and color sight (s) differ substantially from each other illumination color, that is to say they do not have a substantial spectral overlap.

[0067] 具有一个或多个滤色器的示例性符号阅读器。 [0067] or a plurality of color filters having an exemplary symbol reader.

[0068] 图3示出示例性符号阅读器100的内部框图,其与上面图2的示例性符号阅读器100 相似,但是具有额外的元件。 [0068] FIG. 3 shows an internal block diagram of an exemplary symbol reader 100, which is similar to the top view of an exemplary symbol reader 2 100, but with additional elements. 对于两个示例性符号阅读器之间共有的元件中的许多(例如硬件处理器242/244、存储器245/246、总线248等等),下面不重复描述,并且可以假设与结合上文的图2提供的描述基本上相同。 For common between the two exemplary symbol reader many elements (e.g., hardware processor 242/244, 245/246 memory, a bus 248, etc.), the following description is not repeated, and it can be assumed in connection with the above FIG. 2 provides substantially the same as described.

[0069] 在图3的示例性符号阅读器100中,滤光器330、320.1和320.2是成像组件230或照明组件220的元件。 [0069] 100, the filter assembly 230 and 320.2 is an imaging element or the lighting assembly view of an exemplary symbol reader 3 330,320.1 220. 滤波器320/330可以由本领域中已知的多种材料制成(例如,玻璃、树脂塑料、聚酯和聚碳酸酯),并且其可以例如被染色以使光的某些颜色或带宽通过,同时阻挡光的其它颜色或带宽。 320/330 filter may be made by those known in the art a variety of materials (e.g., glass, plastic resins, polyesters and polycarbonates), and which may for example be dyed to certain colors of the light through or bandwidth, or bandwidth while blocking other colors of light. 滤光器也可以被称为“摄影滤光镜(photographic filters)”。 Filter may also be referred to as "photographic filter (photographic filters)". 滤光器可以被染色或者可以被涂覆以实现滤波,并且多个频率可以被单个滤波元件滤波(例如, 使用多个不同滤波材料的涂层)。 Filter may be coated or may be dyed to achieve a filter, a plurality of frequencies and a single filter element may be filtered (e.g., using a plurality of filters of different coating materials).

[0070] 在图中,滤波器320/330被示为与光学器件224/234分离和分开、并且还与图像传感器232和LED/激光器222分离和分开的元件。 [0070] In the drawing, the filter is shown as 320/330 and 224/234 is separated from the separate optical devices, and also the image sensor 232 and LED / laser elements 222 separated and isolated. 在一个实施例中,滤光器320/330中的一些或所有可以在结构上与这些其它部件224/234/222/232分离。 In one embodiment, the filter 320/330 in some or all of these may be separated from the other components 224/234/222/232 in structure.

[0071] 然而,本领域技术人员将认识到的是,此示意性区别是为了说明的目的并且不进行限制。 [0071] However, those skilled in the art will recognize that this difference is schematically for purposes of illustration and not limitation. 在一个替代实施例中,例如,成像滤色器330可以与成像光学器件234或图像传感器232集成。 In an alternative embodiment, for example, an imaging filter 330 may be integrated with imaging optics 232 or the image sensor 234. 例如,成像光学器件234可以包括仅使指定频带通过的一个或多个透镜,或者可以包括仅反射指定频带的一个或多个镜子,以使得成像光学器件234和成像滤色器330在结构上是一个元件。 For example, the imaging optics 234 may include one or more lenses only the specified frequency band, or may include only one or a plurality of reflective mirrors designated frequency bands, so that the imaging optics 234 and 330 are imaged on the color filter structure one element.

[0072] 在一个替代实施例中,例如,与瞄准光116相关联的瞄准器滤色器320.1可以与瞄准光学器件224.1或LED瞄准器222.1集成。 [0072] In an alternative embodiment, for example, with the aiming light 116 associated with the color filter sight aiming optics can 320.1 224.1 222.1 aimer LED or integrated. 例如,瞄准光学器件224.1可以包括仅使指定频带通过的一个或多个透镜,或者可以包括仅反射指定频带的一个或多个镜子,以使得瞄准光学器件224.1和瞄准滤色器320.1在结构上是一个元件。 For example, an optical aiming device 224.1 may comprise one or more lenses only the specified frequency band, or may include only one or a plurality of reflective mirrors designated frequency bands, so that the aiming and sighting optics 224.1 320.1 in the color filter structure one element. 在一个替代实施例中,LED瞄准器222.1可以具有整体的滤色元件或者可以被配置成为了仅生成单个频带,其可以将LED瞄准器222.1所发射的颜色限制到指定频带。 In an alternative embodiment, LED sight 222.1 integral filter element may have or may be configured to generate only a single frequency band, which may be limited to a color LED collimator 222.1 transmitted to the specified frequency band.

[0073] 大体上相似的考虑适用于与照明光学器件224.2和照明LED 222.2相关联的照明滤色器320.2。 [0073] Similar considerations apply substantially to the illumination optics and the illumination LED 222.2 224.2 associated illumination color filter 320.2.

[0074] 本领域技术人员将进一步理解,所示的元件的位置或空间顺序仅为了说明,并且在各种实施例中,在大体上实现相同滤波、光学、照明和图像捕获效果的同时所示的元件的位置或空间顺序可以被改变。 [0074] Those skilled in the art will be further understood that the location or spatial sequence of elements shown for illustration only, and, in various embodiments, at the same time to achieve substantially the same filter, optical, illumination and image capture effects shown position or spatial sequence elements may be varied. 例如,在图3中图示的实施例中,成像滤色器330被图示为接收从符号102反射的光,其然后部分地被发射到(由于滤波)成像光学器件234。 For example, in the embodiment illustrated in FIG. 3, the color image 330 is shown to receive light reflected from the symbol 102, which is then transmitted to the partially (due to filtering) imaging optics 234. 在具有替代结构排序的替代实施例中,符号102所反射的光可以首先被成像光学器件234接收和聚焦,并且然后被成像滤色器330滤波。 In an alternative embodiment with an alternative embodiment of the ordered structure, numeral 102 is first reflected light may be received and the imaging optics 234 focus, and then forming a color filter 330.

[0075] 相似的考虑适用于瞄准光和照明光。 [0075] Similar considerations apply to the aiming light and the illumination light. 例如,在图3中图示的实施例中,来自照明LED 222.2的光首先被照明滤色器320.2滤波到指定带宽,并且然后被滤波的光被照明光学器件224.2聚焦到符号102上。 For example, in the embodiment illustrated in FIG. 3, the light from the illumination of the first illumination LED 222.2 320.2 filtering to filter specified bandwidth, and then filtered light is 224.2 illumination optics 102 is focused on the symbol. 在具有部件的替代结构排序的替代实施例中,来自照明LED 222.2 的光首先被照明光学器件224.2聚焦,并且然后被照明滤色器320.2滤波。 In an alternative configuration sorting member having alternate embodiment, the illumination light from the first illumination LED 222.2 224.2 focusing optics, color filters and is then illuminated 320.2 filtering.

[0076] 滤色器320.1、320.2和330通常用于实现上文讨论的照明和图像捕获过程,其中至少第一频带被用于瞄准扫描器100的目的,并且至少一个有区别的第二频带被用于照明符号102以用于图像捕获。 [0076] The color filter 330 is typically used to achieve and 320.1,320.2 illumination and image capture process discussed above, wherein the at least a first frequency band is used for the purpose of aiming the scanner 100, and at least a second frequency band distinct symbols 102 for illuminating for image capture.

[0077] 如本领域技术人员将要理解的,所示的滤波器中的全部、一些或没有一个可以对实施本系统和方法来说是必要的。 [0077] As those skilled in the art will be appreciated, the entire filter shown, some, or none of the embodiments may be necessary for the present system and method.

[0078] 命名法一滤波器和截止滤波器。 [0078] Nomenclature a filter and a cutoff filter.

[0079] 按照惯例,滤波器常常针对其允许通过的颜色来命名,并且还可以将其称为“带通滤波器”。 [0079] Conventionally, which allows for color filters are often named by, and may also be referred to as "band-pass filter." 例如,蓝色滤波器可以允许蓝颜色通过,同时基本上阻挡所有其它颜色。 For example, a blue color through blue filter may allow, while substantially blocking all other colors. 因此,从表面看起来滤波器一般看上去“带蓝色”。 Thus, from the filter surface it appears generally appear "bluish." 相似地,红色滤波器可以允许与红颜色相关联的波长通过,使得滤波器看起来“带红色”。 Similarly, a red filter may allow the red color associated with the wavelength by such a filter looks "reddish." “截止滤波器”或“阻挡滤波器”是阻挡所指示的频率或颜色的滤波器。 "Cut filter" or "blocking filter" is a barrier indicated frequency or color filter. 例如,“蓝色-IR截止滤波器”或“蓝色阻挡滤波器”阻挡与蓝色(和与红外光)相关联的频率,同时基本上允许其它频率通过。 For example, "Blue -IR cut filter" or "blue blocking filter" blue blocking frequencies (infrared and optical) associated, while substantially allowing other frequencies to pass.

[0080] 一般而言,在本文档中,对蓝色滤波器的引用指代蓝色带通滤波器(其让蓝色通过,并且因此将白光“着色”为蓝色)。 [0080] In general, in this document, references to filter blue blue refer to a band pass filter (which lets through the blue, and thus the white light "colored" blue). 对琥珀色滤波器的引用指代将白光着色成琥珀色的琥珀色带通滤波器。 Reference to an amber filter refers to an amber colored white amber band-pass filter. 在截止滤波器特定地适用的情况下,在文本中通常将对其同样多地进行阐述,然而在一些情况下,根据上下文和元件使用,截止滤波器的使用可以是显然的,甚至在没有如此被阐述时。 In the case of particularly suitable cut filter, which will be generally the same manner as the multi forth in the text, however, in some cases, depending on the context and the element, using cut-off filter may be apparent even in the absence of such when are set forth.

[0081] 在本系统和方法的一个示例性实施例中,符号阅读器100可以采用单色或彩色图像传感器232;蓝色激光瞄准器222.1或蓝色LED瞄准器222.1,或者替代地蓝色瞄准器带通滤色器320.1;以及用于照明滤波器320.2和成像滤色器330两者的蓝色红外(IR)截止滤波器(并且由此从照明光118去除蓝颜色)。 [0081] In one exemplary embodiment of the present system and method, the symbol reader 100 may employ a monochrome or color image sensor 232; a blue LED or a blue laser sight 222.1 222.1 sight, or alternatively aimed blue 320.1 bandpass filter; and means for illuminating both the blue infrared filter 330 320.2 and the imaging filter (IR) cut filter (118 and thus removed from the blue color of the illumination light). 该组合导致从成像过程排除瞄准器频带(蓝色)的成像过程。 This combination results in negative imaging process sight band (blue) from the image forming process.

[0082] 在采用三个滤波器的替代示例性实施例中,激光/LED瞄准器222.1和照明LED 222.2两者可以是宽带光的发射器。 [0082] In an alternative exemplary embodiment using three filters, the laser / LED sight of both 222.1 and 222.2 lighting LED may be a broadband light emitter. 在此类实施例中,瞄准滤色器320.1可以被用来对来自LED瞄准器222.1的光进行滤波以允许第一频带通过,同时阻挡第二发射的频带(其与第一个不同);而照明滤色器320.2可以被用来对来自照明LED 222.2的光进行滤波以允许第二频带通过。 In such embodiments, the aiming filter 320.1 may be used to sight 222.1 light from the LED is filtered to allow the first frequency band, while blocking band of the second transmission (which is different from the first one); and lighting filter 320.2 may be used to illuminate light from the LED 222.2 filtering to allow the second frequency band.

[0083] 与成像传感器232相关联的成像滤色器330还可以被配置成对接收到的光滤波。 Forming a color filter [0083] 232 associated with the imaging sensor 330 may also be configured to filter the light received by the pair. 成像滤色器330可以滤除(去除)瞄准器滤色器320.1所通过的第一频带(由此滤除瞄准器光); 同时允许照明滤色器320.2所通过的第二频率的通过(由此允许图像传感器232接收反射的照明光)。 Forming the color filter 330 can filter (remove) a first frequency band (thereby aimer light filtered) 320.1 sight through the filter; by illumination while allowing a second frequency filters 320.2 through (consisting this allows the image sensor 232 receives the reflected light illumination).

[0084] 在采用两个滤波器的替代实施例中,激光/LED瞄准器222.1可以发射宽带光但是使瞄准器滤色器320.1被配置成仅使光的第一频率(例如蓝色)通过,而照明LED 222.2可以发射宽带光并且不具有相关联的滤色器(因而没有采用照明滤波器320.2)。 [0084] In an alternative embodiment employing two filters, the laser / LED may emit broadband light 222.1 sight but that the sight 320.1 configured to filter only the light of the first frequency (e.g., blue) by, and lighting LED 222.2 may emit broadband light and does not have an associated color (and thus no illumination with filters 320.2). 与成像传感器232相关联的成像滤色器330还可以被配置成对接收到的光滤波。 Forming the color filter 330 and the imaging sensor 232 may also be associated with an optical filter configured to receive. 成像滤色器330可以滤除(去除)瞄准器滤色器320.1所通过的第一频带(由此滤除瞄准器光);同时允许剩余的宽带频率的通过(由此允许图像传感器232接收所有反射的照明光,除了在LED瞄准器222.1的频带中反射的光)。 Forming the color filter 330 can filter out (removed) (aimer light thus filtered) 320.1 sight the color filter by a first frequency band; while allowing through the remaining wideband frequency (thereby allowing the image sensor 232 receives all the illumination light is reflected, in addition to the reflection band of the LED light sight 222.1).

[0085] 在采用两个滤波器的替代实施例中,激光/LED瞄准器222.1和照明LED 222.2可以具有各自的滤色器320.1和320.1,每个被配置成允许不同的频带(例如对于瞄准器是蓝色或红色,但是对于照明光是黄色)的通过。 [0085] In an alternative embodiment employing two filters, the laser / LED lighting LED 222.2 and 222.1 sight may have respective color filters 320.1 and 320.1, each configured to allow a different frequency band (e.g. for sight blue or red, but the illumination light yellow) by. 图像传感器232可以是电荷耦合设备,其仅对黄光或主要对黄光敏感,并且因此主要仅对照明光敏感,而不需要成像滤色器330。 The image sensor 232 may be a charge-coupled device, which is only or mainly yellow Huangguang Min sense, and thus only the main light-sensitive illumination, a color filter 330 without the need for imaging.

[0086] 在替代实施例中,还可以采用多于三个滤波器,例如为了发信号的目的。 [0086] In alternative embodiments, more than three filters may also be employed, for example for signaling purposes. 例如,照明LED 222.2可以具有相关联的照明滤色器320.2,其被配置成仅使第一频带(例如红色)通过。 For example, the illumination LED 222.2 lighting may have an associated color filter 320.2, which is configured to cause only the first frequency band (e.g. red) by. 图像传感器232可以具有成像滤色器330,其被配置成仅使相同的第一频带(在这种情况下是红色)通过。 The image sensor 232 may have an imaging filter 330, which is configured to cause only the same first frequency band (in this case red) through. 激光或LED瞄准器222.1可以是宽带发射器,但是具有多个瞄准器滤色器320.1;于是不同颜色(诸如蓝色、绿色、橙色和紫色)可以被用来用信号通知扫描器100的不同状态。 222.1 sight laser or LED may be a broadband transmitter, but having a plurality of color filters sight 320.1; Therefore, different colors (such as blue, green, orange and violet) can be used to signal the various states of the scanner 100 . 在一个替代实施例中,作为对瞄准器滤色器320.1的代替或者连同瞄准器滤色器320.1—起,扫描器100可以采用发射不同颜色的光的多个瞄准器LED 222.1(蓝色LED、绿色LED、橙色LED等等)。 In an alternative embodiment, instead of the color filter sight 320.1 320.1- or in conjunction with a color filter from sight, the scanner 100 may emit light of different colors using a plurality of sight LED 222.1 (the LED blue, green LED, orange LED, etc.).

[0087] 滤波器的上面的组合仅是示例性的。 The above [0087] The filter combination is merely exemplary. 本领域技术人员将理解的是,在如所附权利要求中阐述的本系统和方法的范围和精神之内还可以采用滤波器的其它组合。 Those skilled in the art will be appreciated that within the scope and spirit of the present system and method as set forth in the appended claims, other combinations of the filters may also be employed.
