    摘要: In a method for position decoding, a position is calculated on the basis of information determined from a partial area, imaged by a sensor, of a position-coding pattern. If the position calculation fails, the information from the partial area recorded by the sensor is matched with information about how the position-coding pattern is designed in a plurality of matching partial areas, which each define a position in the position-coding pattern. The position of the positions defined by the matching partial areas, which according to the matching step is the most probable position in the position-coding pattern for the imaged partial area is accepted as the decoded position. A device and a computer program for carrying out the method are also described.

    摘要: A method and a device for determining a virtual raster of a code pattern consisting of a plurality of marks with associated coordinates mn. Each mark is located at a nominal position but displaced from the nominal position in one of a plurality of directions, depending upon the value of the mark. The nominal positions form raster points gn of the virtual raster, and the raster points are situated on raster lines, which intersect at a first angle. In addition there is a device for determining an initial vector V1,2 on the basis of the coordinates m1, m2 of one or more marks, which initial vector extends approximately between a first and a second adjacent raster point g1, g2. A calculation device determines a second vector V2,3, which forms said angle with the first vector and is the same length as the first vector and extends from the second raster point g2 approximately to a third raster point g3. The mark coordinate m3 which is associated with the third raster point g3 is determined. Subsequently the actual coordinates are calculated for the third raster point on the basis of the third mark's coordinates and its value. The actual coordinates for the third raster point are stored, after which the procedure is repeated taking the second vector as the starting point.

    摘要: In an information code which is arranged to redundantly code at least one first information element by means of a first information element, one or more of the marks can be omitted for the coding of at least one additional information element. In addition, copy protection can be created for an information code that codes at least one first information element by means of a plurality of marks by the addition of at least one interference mark whose optical characteristics differ from those of the marks in the information code. After copying, all the marks will have the same optical characteristics.

    摘要: A position code is applied on a surface to code positions in one or more directions. The code is based on a main number series which has the property that the place in the main number series of each number sequence of a first predetermined length is unambiguously determined. A position is determined based on one or more such number sequences of the first predetermined length. The orientation of the position code is discriminable from the main number series, but only for number sequences of a second predetermined length that exceeds the first predetermined length.

    摘要: A method is provided for decoding data stored in a partial area of a coding pattern on a surface, based on a recorded image of the partial area. The coding pattern contains elements which each have at least two possible decoding values. The method identifies in the image a plurality of elements. The method further calculates, for each identified element, an associated value probability for each possible decoding value that the element has this decoding value. Additionally, the method performs the decoding of data based on the decoding values and the corresponding value probabilities.

    摘要: A method aims at identifying, starting from objects in a digital image, a virtual raster included in a coding pattern. The objects in the image at least partially reproduce marks on a base, each mark being associated with a respective point of intersection of raster lines belonging to the virtual raster. The method comprises the steps of matching sets of objects against a cell unit, which corresponds to a recurring known basic element of said raster; when a set corresponds with the cell unit, identifying the objects in the set as approved; and reconstructing the virtual raster on the basis of the mutual arrangement of the approved objects. A computer program, a storage medium and a device for position determination are also described.

    摘要: A method of providing a position code on a surface, which position code codes a plurality of positions on the surface. A cyclic number series is used, which has the characteristic that the position in the number series of each number sequence of a first predetermined length is determined unambiguously. The number series is printed out a plurality of times across the surface, different rotations of the first cyclic number series being used so that displacements arise between adjacent number series. The surface is divided into a plurality of code windows, which comprise at least three number series and have one number series overlapping one number series of adjacent code windows. The position of the code windows in the x-direction is coded by means of the displacements between the cyclic number series belonging to the code window. A second number series is used for coding in the y-direction. The invention also concerns a method and a device for determining the position, and a device and a computer program product for implementing the method.
