Assignee: HEXAGON TECHNOLOGY CENTER GMBH
Field: Measurement (Instruments)
Classification: CPC G  H | IPC G  H

Claim 8:
9. A target marker locator comprising:
a spatially-resolving optoelectronic sensor for detecting target marker radiation having a known characteristic signature, wherein the spatially-resolving optoelectronic records a first image sequence with a first frame rate and record a second image sequence with a second frame rate different from the first frame rate; and
evaluation electronics configured to:
statistically evaluate the first image sequence, wherein a quality function is determined, the value of which indicates a probability that target marker radiation is detected in a respective pixel, for which purpose the signature is stored in the evaluation electronics,
based on the associated value of the quality function to identify pixels with which target marker radiation is likely detected,
evaluate intensity signals of the second image sequence for said identified pixels, and
to identify target marker radiation from the intensity signals based on the signature.
