    摘要： Described herein is a method for calibrating a detector including at least one camera and at least one projector. The projector is configured for illuminating at least one target with at least one predefined illumination pattern including a plurality of illumination features. 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 target to the camera. The target includes at least one first target and at least one second target. The first target and the second target have a predefined fixed relative distance. The target is positioned at a pre-defined distance from the detector.

    摘要： Described herein is a projector for illuminating at least one object with at least two illumination patterns. The projector includes at least one tunable laser source and at least one diffractive optical element. The projector is configured to generate the at least two illumination patterns each including a plurality of illumination features by controlling at least one property of the tunable laser source. The projector includes at least one control unit. The control unit is configured for controlling the at least one property of the tunable laser source.

    摘要： Disclosed herein is a display device including an illumination source for projecting an illumination pattern including a plurality of illumination features on a scene; an optical sensor for determining a first image including a plurality of reflection features; a translucent display, where the illumination source and the optical sensor are placed in a direction of propagation of the illumination pattern in front of the display; and an evaluation device configured for evaluating the first image by identifying and sorting the reflection features with respect to brightness, each reflection feature including a beam profile, determining a longitudinal coordinate for each reflection feature by analyzing their beam profiles, unambiguously matching reflection features with corresponding illumination features using the longitudinal coordinate classifying a reflection feature as a real feature or a false feature, rejecting the false features, and generating a depth map for the real features using the longitudinal coordinate.

    摘要： Described herein is a method for determining a filling level in at least one storage unit. The method includes illuminating the storage unit with at least one illumination pattern; selecting at least one first reflection feature and at least one second reflection feature; for the first reflection feature, generating at least two first sensor signals, and for the second reflection feature, generating at least two second sensor signals; evaluating the two first sensor signals and the two second sensor signals; determining at least one position of the first reflection feature and at least one position of the second reflection feature and determining at least one first vector of the first reflection feature and at least one second vector of the second reflection feature; and determining from the first vector and the second vector at least one elevation map and determining therefrom the filling level in the storage unit.
