Abstract: A method for calibrating at least one camera (110) and at least one projector (112) of a detector (114) is proposed. The projector (112) is configured for illuminating at least one object (116) with at least one illumination pattern comprising a plurality of illumination features, wherein the camera (110) has at least one sensor element (120) having a matrix of optical sensors, the optical sensors each having a light-sensitive area, wherein each optical sensor is designed to generate at least one sensor signal in response to an illumination of its respective light-sensitive area by a light beam propagating from the object (116) to the camera (110).

Abstract: Material detection, for example classification if skin or non-skin, involving a projector (116) for illuminating an object (112) with an illumination pattern at a first wavelength and a flood light source (122) configured for scene illumination, wherein the flood light source (122) is configured for emitting the scene illumination having a second wavelength; a sensor element for imaging at least one reflection image, at least one evaluation device (136), wherein the evaluation device (136) is configured for determining at least one first material information of the object (112) by evaluating a beam profile (134) of reflection features, wherein the evaluation device (136) is configured for determining at least one second material information of the object (112) by evaluating the scene image, wherein the evaluation device (136) is configured for determining the material of the object (112) using the first material information and the second material information.
