Abstract: Disclosed herein is a method for calibrating at least one camera and at least one projector of a detector. The projector is configured for illuminating at least one object with at least one illumination pattern including a plurality of illumination features, where the camera has at least one sensor element having a matrix of optical sensors, the optical sensors each having a light-sensitive area, where 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 to the camera.

Abstract: A detector for material detection of at least one object is disclosed. The detector includes: at least one projector for illuminating at least one object with at least one illumination pattern; at least one flood light source configured for scene illumination; at least one sensor element having a matrix of optical sensors, and at least one evaluation device.
