Abstract

Facial recognitions of people can be used for the identification of individuals, or can serve as verification e.g. for access controls. The process requires, that the facial data is captured and then compared with stored reference data. In this context, far better recognition performances can be expected from 3-dimensional facial recognition systems than can be from the 2-dimensional systems which are currently used. The accuracy with which the facial profile can be captured, depends on the speed off the measuring data acquisition i.e. the scanning speed and on the measuring accuracy of the measuring device i.e. the 3D scanner.
