    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 detector for determining a position of at least one object. The detector includes at least one sensor element having a matrix of optical sensors, the optical sensors each having a light-sensitive area, wherein the sensor element is configured to determine a reflection image of the object. The detector also includes an evaluation device configured to select a reflection feature of the reflection image, and determine a distance estimate of the selected reflection feature of the reflection image by optimizing at least one blurring function fa, wherein the distance estimate is given by a longitudinal coordinate z and an error interval ±ε. The evaluation device is adapted to determine at least one displacement region in at least one reference image corresponding to the distance estimate, and to match the selected reflection feature with at least one reference feature within the displacement region.
