Description

利用电光扫描捕获签名的方法和装置 An electro-optical scanning method and apparatus using a signature capture

本发明涉及采用电光扫描捕获领取邮件时的签名等一类符号的装置和方法,具体地说就是使用电光扫描器进行这类签名的捕获。 The present invention relates to a method and apparatus using a signature based upon an electro-optical scanning symbol capture receive messages, specifically an electro-optical scanner using such signature capture.

在许多邮递业条中,作为邮件的信、包裹等物品上都贴有跟踪标签。 In many postal industry bar, are affixed with tracking label as a mail letters, parcels and other items. 在跟踪标签上印有可以由人直接识别的跟踪号码等记号和与跟踪号码对应的机器可识别的编码标记。 Printed on the label in the tracking track number or the like can be directly recognized by a person tracking marks and a number corresponding to machine readable coded marking. 跟踪号码是可唯一识别该物品的标记,它有许多同途,特别是可以用于追寻物品在邮递网络中的行踪。 Trace number is a unique identification mark of the article, it has many different uses, it can be used to trace the whereabouts of a particular item in the mail network.

跟踪标签上的编码标记最常见的是通用产品码(UPC)标记,这种标记作为自动识别、追寻目的物的重要手段被广泛接受。 Coded mark on the track is the most common label Universal Product Code (UPC) label, such as automatic identification mark, an important means of pursuing the objective has been widely accepted. UPC标记是一组具有不同宽度、不同光反射率的条和空白线性排列。 UPC tag is a linearly arranged set of bars and spaces having different widths, different light reflectivity. UPC标记可以由包括手提式激光扫描探头、台式工作站、识别笔等激光扫描装置进行电光扫描和识别。 UPC label may be an electro-optical scanning and recognition by the hand-held laser scanner comprising a probe, desktop workstations, such as laser scanning apparatus wand. 由这种装置进行的自动识别可以避免人工识别的错误。 Automatic recognition performed by the apparatus to avoid such errors in the manual identification.

予先印好的跟踪标签上也包括或可以包括记录各种记号的位置。 Tracking preliminarily printed on the label may also include or comprise a variety of recording mark position. 例如,设置记录领取者姓名的领取确认栏,领取人在领取确认栏上签署其姓名或盖章。 For example, set the record field to receive confirmation of the names of recipients, recipients signed or stamped his name on the receiving confirmation column. 也可以设置其他空白处以记录接收时间及认为有必要的任何其他信息。 You can also set other records the receiving time and the space to any other information considered necessary.

在邮递业务中,会遇到许多没有收件人姓名的邮件,为了将邮件送到每个收件人手中一般将这些邮件送到中心领取处。 In postal services, will encounter many messages without the recipient's name, the message sent to each recipient will generally be in the hands of these messages to a central collection point. 总之,收件人在予计期限内没有收到邮件时,为了确认签名的领取人进行紧急问询是邮递业条的一项内容。 In short, when the recipient does not receive the message within the time limit to count, in order to confirm the signature of the recipient's urgent inquiry is an element of postal industry bar. 即使是在这种紧急情况下,邮递机构职员如果见不到带有领取人签名的标签,也难以回答这类问询。 Even in such an emergency, if the Post Office staff did not see the label with the recipient's signature, it is difficult to answer such inquiries. 签标一般都保存在离邮递机构职员较远的地方,所以,这就不可避免地造成答复时间拖后,往往给顾客造成麻烦。 Topics are generally stored in a place far away from the staff of the Post Office, so this inevitably led to delayed answer time, often cause trouble to the customer.

作为处理这类问询的一种尝试,采用了在标签的领取确认栏底下设置纸模压印板的方法。 As an attempt to deal with such inquiries, the method employed in the receiving confirmation column provided under the platen Molded tag. 领取人的姓名以在手写或打印领取人姓名时触压压印板产生的电信号的形式被捕获。 Receiving the person's name is captured as an electrical signal when receiving written or printed name of the generated contact pressure of the platen. 这些信号被收集、存储起来,并可被检索出来。 These signals are collected, stored and can be retrieved. 邮递机构职员即使不用对标签进行人力检验就可以容易地回答顾客的问询。 Post Office staff even without the tag in human testing can easily answer customer inquiries.

这种尝试对于要达到的目的基本上是可以满足的,但是,这种纸模压印板并不是非常有效和绝对可靠的。 For the purposes of this attempt to achieve basically meet, but this paper mold platen is not very effective and absolutely reliable. 当遇到比极限值小的压力时,有可能在纸模压印板记录不下信息。 When faced with pressure less than the limit, it is possible to record information in no fewer than paper mold platen. 也有的领取人怕花费时间或怕麻烦而不愿较确实地压住压印板签名。 And some people are afraid to receive or spend time trouble rather than the more reliably suppress the platen signature.

本发明的目的是进一步提高捕获记号特别是领取确认签名的技术;采用电光扫描器,最好是使用移动光束式或飞点式扫描器捕获记号,可靠地捕获记号,以备以后检索;提供一种在标签上识别个人的方便而且便宜的装置及方法。 Object of the present invention is to further improve the capture token technology especially to receive confirmation signature; electro-optical scanner, a light beam is preferable to use a mobile type or a flying spot scanner captures tokens captured reliably tokens for later retrieval; providing a personal-identification convenient and inexpensive apparatus and method on the label.

上述美国专利都分别对装有光源(最好是气体激光器或半导体激光器)的手提式扫描探头至少作为一个实施例进行了记述。 The aforementioned U.S. patents, respectively with a light source (preferably a gas laser or a semiconductor laser) of the scanning probe at least as a portable embodiment has been described. 为使光源发出的光线形成光束点使用了光学元件。 In order to form a beam of light emitted from the point light source using an optical element. 光束点可以位于紧靠探头的外侧,也可以位于距那里所要求的距离处。 The beam spot can be positioned against the outer side of the probe, it may be located at a distance where the required distance. 扫描元件使光束点扫描形成扫描线。 A scanning element scanning the beam spot scanning lines. 操作员将扫描线置于要扫描的记号上。 The operator is placed on the scanning line to be scanned symbol. 从记号上反射回的光由探头内的光检测器检测。 From the top mark detecting light reflected back by the light detector within the probe. 光检测器产生表示由记号不同光反射部分反射的光的不同强度的模拟电信号。 Generated by the photodetector are represented by different intensities of the light reflection portions different marker light reflected analog electrical signal. 这个模拟电信号被转换成数字化信号,然后根据存储器存储的算法译码。 This analog electrical signal is converted into a digital signal, and then decoded according to the algorithm stored in the memory. 这些都在编好程序的微处理器的控制下进行。 These are carried out under the control of the microprocessor-programmed. 经译码的信号可唯一地识别记号,可以存在探头内,也可以送到主计算机去,这样该记号即被读取。 Coded signal uniquely identifying marks, may be present in the probe, may be sent to the host computer, i.e. such that the read mark.

根据本发明的一个特征,将与图2中标号12所示同样的扫描器用于附加目的,即用于识别、捕获设置在空格16的记号14。 According to one feature of the invention, the scanner will be used with the same reference numeral 122 shown in FIG. Additional objects, i.e. to identify, mark space 16 is provided to capture 14. 记号14与UPC标记那样的可以用机器识别的编码标记不同。 Mark 14 may be coded mark such as a machine recognition of different UPC tag. 这里所描述的记号14是如图1中所示的个人签名。 Symbol 14 described herein is shown in FIG. 1 in personal signature. 当然,这样做是为了便于说明,因为本发明不仅限于捕获手写的签名,也同样可用于捕获其它的图形或盖章或打印的签名或其它各类如手印、符号、记号、微章等标记。 Of course, this is for convenience of description, since the present invention is not limited to handwritten signature capture, also be used to capture the signature or seal, or other graphic or other types of printing, such as fingerprints, symbols, signs, badges, and other markers. 空格16在纵向前后两端有边界线18和20。 A space 16 around the boundary line has longitudinal ends 18 and 20. 最好(但不是必要)空格16在与上述纵向垂直的横向上有两条横向隔开一段距离的侧边线22和24。 Preferably (but not necessarily) in the longitudinal direction perpendicular to the space 16 above the lateral sides with two laterally spaced apart a distance 22 and line 24. 如图所示,空格16的平面图呈矩形,也可以考虑其他形状。 As shown, a space 16 is a plan view of a rectangular, other shapes are also contemplated. 在较佳实施例中,边界线18和20的距离约为2.7英寸(6.86厘米),边界线22和24的距离约为0.4英寸(1.02厘米)。 Embodiment, the distance to the boundary lines 18 and 20 is about 2.7 inches (6.86 cm) in the preferred embodiment, the boundary lines 22 and 24 from about 0.4 inches (1.02 cm).

签名14签在空格16内,占用空格的任何区域或象素。 14 signature sign in the space 16, the space occupied by any region or pixels. 这个空格可以考虑是由许多按沿纵向延伸的行和沿横向延伸的列组成的阵列分布的区域构成的。 This space may be considered by a plurality of rows extending in the longitudinal direction and by regional distribution along the array of transversely extending columns constituted. 各区域越小,捕获的签名的清晰度就越大。 Regional smaller signature capture greater clarity. 理论上,如果上述行和列的数目是无限的,就可以得到最清晰的图像。 In theory, if the number of columns and rows is unlimited, you can get the clearest image. 实际上只要每英寸有大约100个区域就可以得到具有满意清晰度的签名。 In fact, as long as there is about 100 areas per inch you can get a signature with a satisfactory resolution.

占用区域,即有签名的部分的区域的光反射率与非占用区域即没有签名部分的区域光反射率不同。 Occupied area, that is the light reflectance of the non-occupied area that is not part of the signature region different regions of light reflectance signature part. 占用区域与UPC条形码的条相类似,而非占用区域则与UPC条形码的空白部分相类似。 Article occupied area similar to a UPC bar code, rather than with the occupied area of ​​the blank portion similar to a UPC bar code. 占用区域代表二进制中的″1″,而非占用区域则代表二进制中的″0″。 Occupied area represents a binary "1" rather than occupied area represents a binary "0." 扫描器12的扫描线走过空格内的一行区域时,占用区域反射的光少于非占用区域反射的光。 When the scanner scans the line 12 through a line region in the space occupied area than the non-reflected light reflected from the region occupied by light. 这种变化的光信息可用与处理UPC标记完全类似的方法处理成表示签名的数据。 This change in the optical information processing can be used to represent the signed data processing method entirely analogous UPC tag.

但是,UPC标记是一维的,只要在其高度方向(即横向的Y轴)的任一处由扫描线进行扫描就可以读得数据;而鉴名包括了纵向(X轴)及横向(Y轴)两个方向的信息,是二维的。 However, the UPC label is one-dimensional, any long in height direction (i.e., transverse to the Y-axis) of a scan by the scanning lines can be read transactions; and Kam name includes longitudinal (X-axis) and transverse (Y information on two axes directions), is two-dimensional. 为了再现二维的签名,还需要知道,某一特定的扫描线正在扫描哪行区域,以及各扫描线何时进入和离开含有签名的空格。 In order to reproduce the two-dimensional signature, also you need to know a particular region of the scanning line which line is being scanned, the scanning lines and when entering and leaving a space containing the signature.

本发明建义在空格16的前、后端(沿纵向考虑)分别设置多行前端码装置26和多行后端码装置28。 Construction of meaning of the present invention before a space 16, a rear end (considered in the longitudinal direction) are provided a plurality of rows 26 and distal code decoding means 28 the rear end of a plurality of rows. 每个码装置是多行标记结构,设置有可被电光扫描和读取的沿纵向和横向排列的编码数据。 Each code means is a multi-line label structure, there is provided an electro-optical scanning and can be read in vertical and horizontal alignment of the encoded data. 每个标记结构可以是一个唯一的二维标记结构,如一个分行的条形码或一个与流行的标准条形码结构相兼容的新的记号结构。 Each marker structure may be a two-dimensional mark unique structure, such as a bar code or a branch compatible with popular standard configuration of a new bar code symbol structures. 一种适用于前,后端码装置26、28的多行条形码已在美国专利第4,794,239号中做了公开,其内容在这里作为参考引用,也请参考图6。 One for the front, the rear end of the code means 26, 28 have been made in a plurality of rows barcode U.S. Patent No. 4,794,239 the disclosure of which is incorporated herein incorporated by reference, see also Fig.

各端码装置26、28将其编码数据设置于多个纵向的行1、2、3、4……N上,其中,N是可以得到签名的较佳清晰度的足够大的数值。 Each end of the code means 26 be disposed on the encoded data in rows 1,2,3,4 ...... N of a plurality of longitudinal, where, N is a sufficiently large value can be obtained signature preferred definition. 理论上,当行数无限时可以给出最好的清晰度,但是实际上只要有25行就可以得到相当清晰度的签名。 In theory, an infinite number of lines can be when given the best definition, but in fact there are 25 rows long as you can get quite a clarity signature. 这些行是在横向上依次层层排列。 These lines are sequentially arranged in a horizontal layer.

编码数据的各行包括一个用于判定一特定时间一扫描线正在扫描那一行的行识别装置。 Each row of encoded data includes a specific time for determining a scan line is a scan line of the row recognition means. 如图1所示,就水平扫描线30而言,端码装置26、28各自的行识别装置包括识别出该瞬间正在扫描的行是第3行的数据。 1, on the horizontal scan line 30, the end of the code means 26, 28 comprises a respective row recognition means recognizes the moment is being scanned line data of the third row. 仍如图1所示,就倾斜扫描线32而言,前端码装置26的行识别装置包括识别出该瞬间正在扫描的行是第1行的数据,后端码装置28的行识别装置包括识别出该瞬间正在扫描的行是第2行的数据。 1 still, is inclined to the scanning line 32, the front end of the line code recognition apparatus comprises means 26 recognizes that the moment is being scanned row is a first row of data, the rear end of line code identification means includes an identification device 28 the rows of the moment is being scanned data in the second row.

各编码数据行还包括用于判定何时各扫描线走过空格16的前后边界线的同步装置,即开始/停止数据。 Each row further includes a coded data for determining when each scanning line through the boundary line synchronizing means before and after the space 16, i.e. start / stop data.

使用时首先使扫描器12产生一以零偏角水平扫过识别构造10的扫描线(如扫描线30),即,同一扫描线走过前端码装置和后端码装置的同一行。 When the scanner 12 is first used to generate the scanning line (scanning line 30) to a level of zero sweep angle 10 is configured to identify, i.e., the same scanning line gone through in the same row code means and the rear end of the front end of the code means. 扫描线30过扫描识别构造10。 Scan lines 30 through 10 configured to scan identification. 例如,一4英寸(10,6厘米)的线性扫描,足以覆盖前端码、后端码装置及空格16的长度。 For example, a 4-inch (10,6 cm) of the linear scan, enough to cover the front end of the code, the code length of the rear end 16 of the apparatus and spaces. 过扫描有助于减小扫描线两端光束点速度的不均匀。 Help the overscan at both ends of the beam point velocity unevenness is reduced scanning lines.

将扫描器12置于识别构造的上方,然后,操作员用手横向移动扫描器通过识别构造直到其低于识别构造。 The scanner 12 is placed over the identified configuration, then, the operator manually moves laterally until it is configured by identifying scanner identification structure below. 在手动移位过程中,具有相同行号的前端行和后端行由相同的扫描线扫描,各对对应行先后被扫描。 In the manual shift process, the front row and rear rows with the same number of rows, each of the corresponding row has been scanned by the same scan line. 扫描器12所带的光检测器检测前端码、空格内的占用区域及非占用区域和后端码反射的变化光强度。 An optical scanner 12 carried by the distal end code detector, light intensity variation and the non-occupied area occupied area code and a rear inner space of the reflector. 如图1所示,对于走过各前端装置、后端码装置的第3行的扫描线30,签名14与扫描线30的交叉点表示一个占用区域,签名14与扫描线30的所有不交叉的点表示非占用区域。 As shown, for each of the front-end device through the scanning lines row 3 of the rear end of the code means 30, 14 and cross point scanning the signature line 30 represents an occupied zone 1, all of the signature 14 with the scan lines 30 do not intersect the dots represent non-occupied areas.

对应于各端码装置及占用区域、非占用区域的电模拟信号,由光检测器产生。 Code corresponding to each terminal device and the area occupied, unoccupied areas electrical analog signals generated by the photodetector. 这些模似信号通过模似/数字转换器数字化,在微处理的控制下根据一算法译码。 These analogue signals by the analogue / digital converter digitized under control of the microprocessor in accordance with a decoding algorithm. 译码信号被存入存储单元中。 Decoded signal is stored in the storage unit. 被贮存的信号可以从存储单元中检索出来,因而签名可以在显示屏幕或打印机上重新形成。 The stored signal may be retrieved from the storage unit, so that the signature can be re-formed on the display screen or printer.

实际上,扫描线不可能被精确置于识别构造上而使扫描线扫过前、后端码装置中相同的行。 Indeed, the scan line can not be accurately placed on the front configured to identify the scan line across the rear end of the code means the same row. 通常,扫描线如具有代表性的倾斜线32所示,显非零斜率倾斜。 Typically, the scanning lines as shown in the representative line 32 is inclined, the inclination significantly non-zero slope. 尽管如此,用与上述类似的方法,扫描器12置于记号上方,并用手沿横向向记号的下方位置移动。 Nevertheless, using a method similar to the above, the scanner 12 is placed above the mark, and the hand is moved to the lower position in the lateral direction mark. 各扫描线的前端行、后端行被分别记录,因为空格16的尺寸是预定的,因而可以计算出斜率。 The front end of each scanning line of the row, the rear end of the row is recorded, respectively, as the size of the space 16 are predetermined, it is possible to calculate the slope. 这样,就各扫描线而言,就可知道其经过行的前端行行号,经过行的后端行行号、以及该扫描线上的占用区域及非占用区域。 Thus, for each scanning line, after the front end you can know which line number of the line, the line through the rear end line number, and the occupied area and the non-occupied area of ​​the scanning line. 所有这些信息都被分别贮存在存储单元内,根据需要可以进行检索和在显示屏幕上及打印机上重新构成记号。 All this information is stored in the storage unit, respectively, can be retrieved and re-configured as required mark on the display screen and on the printer.

也可以不将扫描器在横向上手动移位,而使扫描线本身自动地沿″Y″轴扫描。 The scanner may not be manually displaced in the transverse direction, the scanning line itself automatically in the "Y" axis scanning. 例如,扫描器的输出可以不是上述单一的扫描线,可以用由一组相互平行的扫描线组成的光栅形式。 For example, the scanner may not output said single scan line can be composed of a set of raster scan lines parallel to each other in the form of a composition. 例如,可以参考美国专利第4,816,661号。 For example, with reference to U.S. Patent No. 4,816,661. 这项美国专利的全部内容都在这里作为参考资料引用。 The entire contents of US patents are cited here as a reference.

扫描器12可以用手操作,以不与识别构造接触的方式置于远离要扫描记号的地方(参照图2),或者在使用识别笔34的情况下,(参照图3),将扫描器以接触方式设置在对着识别构造的地方。 The scanner 12 can be operated by hand, so as not to contact with the structure placed apart from the identification indicia to be scanned (refer to FIG. 2), or in the case of using the identification pen 34, (see FIG. 3), to the scanner disposed opposite the contact place identification configuration. 也可设成扫描工作台36,扫描装置本身位置固定而无需移动(参看图4),识别构造10相对于扫描工作台36移动。 May be provided to scan table 36, the fixing position of the scanning device itself without moving (see FIG. 4), the identification structure 10 to move relative to table 36 is scanned. 例如,将识别构造10通过传送带38传送通过固定工作台36。 For example, the structure 10 identified by the transfer belt 38 by the fixing table 36.

如图5所示,跟踪标签40上印有识别构造10,而且标签40上含有可由人识别的由阿拉伯数字的多位数码组成的跟踪号42。 5, a tracking label 40 printed on the identification structure 10, and contains a digital tracking number digits from a number consisting of 42 identified by a person on the label 40. 标签40还含有UPC标记44,它是可由电光扫描器识别的机械可读数字,可以将它译码为跟踪号42。 UPC label 40 also contains indicia 44, which is identified by the electro-optical scanning machine-readable numbers, which may be coded as a tracking number 42. 标签上还含有填写要邮递的物品50的重量及运送号码的地方46、48。 Weight on the label also contains a number of articles and local delivery of 50 to fill out the mailing 46,48. 标签40通常具有压敏的可粘的背面,该背面用以贴到邮件50上。 The back surface 40 generally with a pressure sensitive adhesive label attached to the back surface 50 to the message. 也可将该标签插入一个可靠地固定在邮件50上的口袋里。 The tag may be inserted into a securely fixed in the pocket 50 on the mail.

如图2-图4所示,将标签40贴在邮件50上时,以一般方式使用如12、34、36的扫描器可以读取上面的UPC标记44。 When as shown in FIG. 2- 4, the label 40 on the message 50, such as a general way to use the scanner can read the above 12,34,36 UPC tag 44. 同时或接着,可以用扫描器读取识别构造10,其上具有填有签名14的空格16。 Subsequently or simultaneously, it may be configured to read the identification with the scanner 10, which has filled the spaces 14 of the 16 signatures.
