Method for identifying measuring points in an optical measuring system

Method for identification of measuring points in an optical measurement in said system a plurality of active or passive to score points as targets is used, in which a specific system measuring points are marked with a target or an arrangement of a plurality of targets, wherein each target is a point code element having an intensity and / or specific size, and that for identification of the measuring points the intensities and / or sizes of the elements are recorded point code (4, 10), in which a system in which a punctual code element is associated with each measuring point, the identity of the measuring point is coded by the intensity and / or specific size of each specific element code, which is different from the intensity and / or size of the other specific code elements, and in which in a system in which an array of target is associated with each measuring point, the specific elements of code in the they have provision of at least three intensities and / or different sizes.
