Claim 0:
1. An optical measuring method for the three-dimensional detection of the surface of an object using an optical recording unit, comprising:
moving the optical recording unit relative to the object during a first measurement time interval;
illuminating the object, by the optical recording unit, during the first measurement time interval, using an illumination beam with a light intensity;
successfully detecting, by the optical recording unit, a plurality of height maps each comprising a pixel matrix or image matrix in which each pixel or image point thereof contains three-dimensional information, at a recording frequency during the first measurement time interval;
adding at least a portion of the detected plurality of height maps to an overall height map that represents an accumulation of height maps recorded during the first measurement time interval and
displaying the overall height map,
wherein the light intensity and/or the recording frequency are regulated during the measurement time interval by means of control signals;
wherein the control signals are generated at time intervals during the measurement time interval, and
wherein each control signal is generated on the basis of at least one sensor signal of at least one temperature sensor.
