According to the abstract released by the Intellectual Property India: "The invention relates to a method for ascertaining at least one degree of freedom of a camera (1) relative to a code arrangement (2) from a camera image of the camera (1). The code arrangement (2) has a point grid with a plurality of base symbols (20), wherein a coarse position of the base symbols (20) is coded in the code arrangement (2), and a starting field (28) with base symbols (20) is determined. The starting field (28) has at least three base symbols (20), and two independent main directions along the point grid are estimated in the camera image via the base symbols (20) of the starting field (28). The base symbols (20) of the starting field form valid base symbols, and additional base symbols (20) are searched for in a searching step on the basis of at least one valid base symbol (20) along at least one of the main directions. In the event of a successful search, the additional base symbols (20) are characterized as valid base symbols (20). The searching step is carried out multiple times, and on the basis of the valid base symbols (20) or a sub-quantity thereof, the coarse position of at least one of the base symbols (20) in the code arrangement and/or the coarse position of the coordinate system of the point grid is ascertained as two degrees of freedom of the camera relative to the code arrangement (2)."
