Method for identifying measuring points in an optical measuring system
First Claim
1. A method for identification of measuring points in an optical measuring system in which system an arrangement of a plurality of active targets is used for marking each one of the measuring points, each of said targets having a different intensity and wherein, for identification of the measuring points, the intensities of the active targets (4, 10) are registered.

Abstract
In an optical measuring system for determining spatial position and orientation of objects, a plurality of measuring points on the object is registered by cameras, laser measuring devices or a combination thereof. For identifying the measuring points, one target of a specific intensity and/or size or a predetermined pattern (3) of a plurality of targets (4) having specific differing intensities and/or sizes is associated with each measuring point. The intensities and/or sizes of the targets are detected in a pixel image of the target (4) by summing up intensities sensed by pixels included in the image of the target. The targets are light emitting devices consuming differing amounts of energy, reflecting, black or white spots of differing diameter or spots of differing shades of gray or other suitable color.

4. An optical measuring system comprising:
-
a set of arrangements of a plurality of active targets (4, 10) each arrangement serving for identifying one measuring point in an optical measuring system, wherein the targets (4, 10) of each arrangement are arranged in a same pattern (3) or in differing patterns and wherein the targets (4, 10) have differing intensities; and sensor means being equipped for determining intensity of the targets in the target arrangements. - View Dependent Claims (5, 6)

- 7. A method for identification of measuring points in an optical measuring system in which system an arrangement of a plurality of active targets is used for marking each one of the measuring points, wherein each arrangement is different from the other arrangements by different target intensities and wherein, for identification of the measuring points, the target intensities in each arrangement are registered.
