    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 product is provided with a coding pattern, which codes position information in the form of coordinates for a plurality of points on the product with the aid of a plurality of marks belonging to each point. The marks have a first parameter which varies for coding of the position information. The marks additionally have a second parameter which varies for coding of further information in the coding pattern. A method and a device for coding of the coding pattern and a method and a device for decoding of the coding pattern are also described.

    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： In a method for position coding, positions are coded in a first dimension on a surface in accordance with a primary number sequence that has the property that the place in the primary number sequence of each partial sequence of a first predetermined length is unambiguously determined. Each position in the first dimension is coded by one of the partial sequences. The primary number sequence is built up of at least two secondary number sequences that have a smaller base than the base of the primary number sequence and that are used for determination of the partial sequences of the primary number sequence which correspond to the positions in the first dimension. This makes possible, among other things, realization of the method in devices with limited memory capacity, as the secondary number sequences require less memory in total than the primary number sequence. The secondary number sequences can also be used for decoding the position code.
