An application of such encrypted circular labels is the positioning and encryption of circular frames. Timber recognition and subsequent recognition automation by decoding encoded circular labels. be.

As each lumber arrives at the scanning station, a seven digit-set number is assigned to the lumber. Total The calculator has a circular black barcode pattern with a diameter of 18 cm for its 7 digit numbers. Create a copy of Bell on a white plastic board. The label symbol is shown in Figure 3. It's like being there. In this example, the plurality of individual rings are 3 mm It has a width. A plurality of white plastic plates are then preferably made of corresponding material. Fixed to both ends of the tree.

A grab then grabs the bundle of timber and transports and loads it onto a ship or truck for transport. First, the grab traces the recording area. In its recording area, the grab is In fact, the scanning position is moved and then the grab is held stationary by multiple blocks. It will be done. Next, the − set of floodlights will automatically turn on and one end of the lumber bundle will be All timbers within a number of jaws to be scanned at one time are scanned.

Once the scan is complete, the floodlight is turned off and the block is removed. And then Love moves on to transporting the lumber to trucks and ships.

In another embodiment, as shown in FIGS. 1 and 2, a floodlight 15 is installed. A movable recording stand 13, a power source 16, a dual camera/ The calculator 17 connected to the range finder unit 19 and the control box 14 is The line of approach is preferably set on the pedestal 201 by means of a movable ram. It can also be used to approach a bundle of timber 12°202 that has been rolled over 180°. Wear. The recording stage acquires the image at one end, that is, the composite image 200, moves to the other end, and records the composite image 200. Obtain the second image. The information is output to a distant analysis unit by the radio 18. .

The characteristic image has a more disordered background than that in Figure 2, but the content shown in Figure 2 holds something similar.

The image 200 has sufficient resolution so that each item (here lumber 202) This makes it possible to decrypt each label 204. This is shown in the drawing. This type of label is remanufactured as shown in FIG. Uke is also stand 201 Has a recognition screen or radio detection symbol, such as a barcode or radio recognition tag 203. It is desirable that the location of the item be located at the time of recording. .

The pixel density is contained within the pattern used to indicate the end wood of each timber. is desired to be lower than the multiple squares that are included. The characteristic line scan camera is 3 It has a 3456 photodiode CCD linear array with 456 pixel columns. IL Preferably, 200 rows are combined to form one image. Characteristic The area acquisition camera captures a portion of the pedestal and collects them into one complete pedestal. Each acquired image (forming) 4096 pixel columns and 4096 It has a 4096x4096 photodiode CCD array giving a row of Ru.

The scanned complete image locates all label frames and their respective labels. is analyzed by a computer to recognize the timber based on this information. circular barco In the case of code (300, 301), due to the circular state of the encrypted label, some A proxy value is calculated by analyzing several different radius sections to obtain information redundancy. Ru. For alphanumeric codes, the symbol representing the code is duplicated several times. statistically appropriate Some Latin route replication methods are preferred. Due to multiple overlaps, dust and other contamination or CC Protects against lack of information due to deterioration of encoded label quality due to defective D element. management is carried out. Multiple types of codes incorrectly decoded after - number of analysis scans Processing is performed to prevent this from happening.

The acquired images are limited and recorded in a remote computer section (not shown) by the radio 18. output for recording, next analysis and later observation. The analysis calculation program is Dynamically search recorded images, analyze the retrieved images, and analyze the analyzed images. A file of the decoded recognition code is generated.

According to the invention, a pre-printed label can be suitably used as shown in the embodiment of FIG. 1O. The marking is applied onto a type of paper material. Paper materials used for labeling must have a blank surface. Glossy, plastic-containing paper is suitable and will protect the toner during laser printing. – Must be able to withstand the heat applied during melting. This label 1001 has a circle shape. and the direction symbol 1002, which is an open oval row on the information retention symbol. have.

Also, a pre-printed label 1100 with a miniature symbol 1102 as an outline can also be used in the form shown in FIG. On the other hand, an open oval 110 3 is used for direction display. This label is also shown as grid 1101 It has a registration display 1101 that is used for accurate positioning of the information-bearing symbol. ing.

Application example using alphanumeric and symbolic codes FIG. (This is label 204 in FIG. 2). contour 40 If 0 does not indicate the direction of the information, have an open oval column over the text. A second contour indicating the direction of the information.

The embodiments shown in FIGS. 4 through 9 and in FIG. 12 include alphanumeric recognition codes. and labels with joint spatial overlap are used. Figure 5, Figure 7, Figure 9 and Figure 1 The second label consists of a frame with a pair of open and closed ovals, respectively. surrounded by In Figure 6, a contour with letters is used, and in Figure 8, an open Closed triangles and closed triangles are used. adapted to computer recognition Therefore, the most suitable symbol to use for the frame symbol is an oval, followed by a triangle, and then a triangle. Next is the order of letters.

A label 1200 is shown in FIG. 12, and the label 1200 is a 3×9 limited Due to multiple types of codes 1201 mixed within the Latin route replication It is configured.

Any label shown in Figures 3 through 9 or 12 may be attached to a single or bundle of lumber. , or when handling items such as lumber on boards, one or more boxes, and is suitable for recognizing items after handling.

The small overlapping characters suitable for our desired outline symbol can be found by mechanically scanning the large array. and is easy to recognize thanks to machine screen algorithms that detect recognizable labels. . Multiple symbols, arcs, or a complete circle are preferred over straight frames. because , an arc, or a circle shows the location of relevant information more clearly than a straight line, and is more concise. This is because position determination can be easily performed. Arcs can be created by analyzing just two columns or rows. position can be determined. To distinguish them from arcs, multiple lines have more columns and rows. and an end point. For example, a single straight line is difficult to position and is generally Seen within the image background. And the location of that information remains unclear.

For example, if you apply a pattern matching algorithm outside one or more labels, Position special characters that are selected at least in part because they are relatively rare in the world. It can be used to determine the Originally, elliptical and triangular shapes were It has the property of indicating direction.

In the case of this illustrated example (specifically the encrypted circular label shown in Figure 3) ), the applied label 204 is (a) placed within a circular frame of an identifying color; or (b) has a color significantly different than the identifying color of the growth ring. This distinguishes it from the growth ring of timber 202.

Encrypted alphanumeric labels 400, 500, 700, and 900 have a recognition An open circular or An oval shape is used. Alphanumeric labels 800 use triangles.

At the end of the string that forms the recognition code, a complete “0”-like shape appears in the frame. It is desirable to use it as part of Except for the alphanumeric label 900, there are two codes. A recognition code for the spatial order in which the code line has been rotated is added below the At the end, a complete circle or oval is applied. Under the third recognition code column has a column of complete symbols (parts of the frame), and (positionally) the position of the code above it Recognize. Regarding the alphanumeric label 900, it is composed of eight recognized characters. The column is duplicated seven more times with spatial rotation. And the perfect Latin square shape will be accomplished. Furthermore, regarding the alphanumeric label 900, the complete symbol string is the 8th is placed under the recognition line to form a closed frame.

Multiple alphanumeric characters are selected from a fixed-width font for Roman characters, all separated by It has a different easy character style. As long as it is compatible with machine recognition, Fonts from countries that use Cyrillic or Katakana are preferably used. stomach. Some fonts include the number 1, the bottom °bi, or the number °0 (zero)'. Most of the newspaper fonts that should be appropriate, such as the English letters “0” and Q, There are characters with no difference. Such characters will be changed. For example, 8 in “Additional notes” The character indicating the 370th number is a hatched character "1". Also, another method and shall include at least one set of informational offers printed on at least one different code. Common symbols can solve the problem of ambiguity.

The nine letters in particular mentioned above are characteristically partially or wholly mxn Latin square. Copy a case path (Figures 4 to 8 show examples with m=3 and n=9) . In this format, the complete code is displayed in three horizontal columns below the positioning frame. is copied to. and is also duplicated in a set of three lines (in Figure 9, eight characters are , shown in full 8x8 Latin square form). In particular, the one that sets the law Only the Latin path is used for all labels in one application.

The application of such encrypted alphanumeric labels is to recognition and next time automatic recognition and decoding of said encrypted alphanumeric characters.

As each lumber is received in the advance preparation base, nine character recognition is applied to the lumber. Assigned. Recognizes numbers from 0 to 9 as well as upper and lower alphabetic characters Used within the code. In our preferred embodiment, the An elliptical recognition frame that copies a spatially balanced pattern of knowledge that also recognizes direction. Produced on a 18cm x 13cm white plastic paper surrounded by Ru. Individual alphanumeric characters have a maximum width of 15o+ at a height of 15mm in a 15mm wide space. It is m. A second simultaneous readable code of letters and spaces is displayed within the label. It is desirable to be used with spatial rotation, and accurate recognition of subsequent computational analysis is possible. The possibility of Figure 7 shows such an encrypted label. , A barcode is pasted outside the frame. It allows simultaneous use of other parallel methods. It becomes possible to use 18cm x 13cm white plastic paper is secured to both ends of the timber. It is desirable that the

After being acquired and output, the scanned image (see e.g. Figure 1 above) is automatically calculated. A computer analyzes the positions of all label frames and encrypts the label values. Recognize those timbers based on. Labels can be marked with oval or circular borders. Recognition and correction of plane distortions in images (e.g. perpendicular to an object parallel to the optical axis) 2) is possible. In addition, the frame makes it easy to determine the rotation direction of the image. Become. Additional copies or duplications of spatially isolated recognition codes may result in contamination. degraded quality of encrypted labels due to or other contamination, damaged labels, CCD elements. 2/3 labels are unclear (unreadable) due to damage to children, regions, rows, and columns It is possible to regenerate recognition even after it has occurred.

The acquired images are recorded wirelessly for subsequent analysis and later observation. It is desirable that the data be output to a remote computer. The analytical calculation program automatically Search and analyze the recorded images, and create a file of the decoded recognition code for each image. generate a file. The typical delay time from the start of image acquisition to the end of analysis is This can be 33 seconds for a computer device. Of course, the output of the image is the first scanned Starts as soon as data is available.
