Claims
- 1. A measuring device for the location and attitude determination of an object, comprising a plurality of light sources disposed on the object, optical means for reproducing the object with the light sources on a position-sensitive detector, the position-sensitive detector comprising two electrode pairs which define a coordinate system on the detector surface and generating partial electric currents, each of the plurality of light sources being intensity-modulated with a different code frequency, and evaluating means for computing simultaneously the image coordinates of the light sources from the partial electric currents of the position-sensitive detector using a frequency multiplexing process.
- 2. The measuring device recited in claim 1, wherein the evaluating means comprises on an input side a summing means for forming the sum and the difference of the partial electric currents of each of the two electrode pairs and a plurality of frequency-selective filters connected in parallel to each other downstream from the summing means, each frequency-selective filter being adjusted to another one of the code frequencies.
- 3. The measuring device recited in claim 2, further comprising a plurality of computing units coupled to the frequency-selective filters for computing the image coordinates of the light sources from the selected sum and difference signals.
