Abstract: The invention relates to generating a total data set of at least one segment of an object for determining at least one characteristic by merging individual data sets determined by means of an optical sensor moving relative to the object and of an image processor, wherein individual data sets of sequential images of the object contain redundant data that are matched for merging the individual data sets. In order that the data obtained by scanning the object are of sufficient quantity for performing an optimal analysis, but without being too great an amount of data for processing, the invention proposes that individual data sets determined per unit of time be varied as a function of the relative motion between the optical sensor and the object.

Abstract: A method for detecting contour data of a three-dimensional object, where a grid of illumination points of a multi-point illumination is projected onto the object using an optical device and the illumination points are then projected back onto a sensor containing pixels. In order to improve signal-noise ratio and reduce background signal, it is proposed that a grid of illumination points of at least two multi-point illuminations are projected onto the object, that the beams of the illuminating points of are modulated in intensity and that a frequency-selective and/or phase-selective detection is performed of mutually associated first and second illumination points back-projected onto the sensor. The first illumination points derive from a first of the multipoint illuminations and the second illumination points derive from a second of the multipoint illuminations.
