摘要:
In a method for marking a product first a product identification (12) is generated (S1) and applied (S5) onto the product (21). Subsequently the product identification (26) applied onto the product (21) is captured (S6) and stored (S8, S9) in a product database (11). Here in particular also an independent authentication feature (22) is designated (S3, S5) and applied (S6) together with the product identification (26) onto the product (21) and stored (S8, S9) in the product database (11).
摘要:
Disclosed is a two-dimensional code which is not likely to be affected by contamination or out-of-focus photographing thereof and can thus be accurately recognized in a short time even when it is photographed under various photographing conditions. The disclosed two-dimensional code comprises: cells representing binary-coded data that are arranged as a pattern in a two-dimensional matrix; and four or more different position detection patterns.

Techniques are provided for generating machine-readable optical codes that have an aesthetic component that is integrated into the codes themselves. In this manner, the machine-readable optical codes can be designed to be aesthetically pleasing and/or can convey information to human viewers, and can even be disguised so that they do not appear to be machine-readable optical codes at all. Such information can be (but need not be) distinct from the information encoded for reading by a machine, even when the information is integrated into the code itself. The techniques described herein can be applied to any type of machine-readable optical code.
摘要:
An article to which a visual code is attached, wherein the visual code includes: a frame pattern which is formed in the shape of a polygonal or round ring by arranging multiple pattern elements; a symbol pattern placing area which is formed inside the frame pattern, and in which a symbol pattern can be placed; an internal information pattern which is formed as a part of the frame pattern and indicates the presence or the absence of the symbol pattern in the symbol pattern placing area; and a guide pattern which is placed on, inside or near the frame pattern, and is used for a visual code reading apparatus having an optical reading function to recognize a positional relationship between the frame pattern and the visual code reading apparatus.

A method for encoding the color of an object in multispectral form by adaptive compression, includes the following steps: determining an identifier of the color in the form of a logistics-dedicated code and having a European Article Numbering, Universal Product Code, or Domain Name System distributed management structure; inserting a marker at the beginning of the code indicating that it is a color code, and the type of storage; and creating a color encoding that can be interpreted by both a human being and a computer by being directly read, in the form of three elements, a sample of the color or texture, a name, and a barcode/chip, using the code and the marker, which provides access to the bidirectional spectral reflectance of the color stored either locally and/or on a network, and having a rendering model that is predetermined by the marker. The associated decoding method is also described.

An encoding method is provided. The encoding method comprises: encoding a first portion of target data to generate a first two dimensional code; encoding a second portion of the target data by the encoding unit generate a second two dimensional code; generating a three dimensional model according to the first two dimensional code, wherein the three dimensional model includes a plurality of three dimensional modules, the three dimensional modules are arranged along a first direction and a second direction, and a height in a third direction of the three dimensional modules is determined according to the first codes; coloring the three dimensional modules according to the second two dimensional code, respectively, to generate a colored three dimensional model, wherein a color of the three dimensional modules of the colored three dimensional model is determined according to the second codes.
摘要:
In order to increase safety, a computer-implemented method is proposed for determining the position of a lift cabin in a lift shaft with the aid of a coding device, in which method a section of a code band and/or of the bearing device is/are recorded with an optical detection device as a pixel image consisting of pixels, a reference marking analysis is carried out, the pixel image is processed, in particular is assigned to a detection grid, pixels of the pixel image are preferably combined with the aid of their color and/or position in order to be able to read out the barcode and/or 2D code of the marking, the barcode and/or 2D code is converted to a binary code, the binary code is decoded by means of an algorithm and is converted into a position indication and/or into information as to whether a bearing device has been detected.
摘要:
A method and program for encoding and decoding color barcodes to increase their data capacity. The encoding steps include determining a shape and a color for each data cell to encode digital data, wherein a combination of the shape and the color for the data cell is chosen from a plurality of combinations of shapes and colors in accordance with a value of the digital data to be encoded, and coloring a subset of the plurality of pixels in each data cell in accordance with the shape and the color for the data cell determined above. The decoding steps include segmenting the data cells in a color barcode, recognizing a shape formed by a subset of pixels in each data cell and the color of the shape, and obtaining digital data from a combination of the recognized shape and color in each data cell.
摘要:
A printed information device includes a region of interest in an image, and at least two channels assigned to the region of interest by different means of logical partitioning. The region of interest represents a physical area of the image. Each of the channels has a different error tolerance. Continuous and/or cyclic information is independently encoded in each of the at least two channels. The deterrent is configured to be read substantially simultaneously by at least two distinct reading strategies.
