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: 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 projector and illumination module configured for scene illumination and pattern projection. The projector and illumination module includes at least one array of a plurality of individual emitters and at least one optical system. Each of the individual emitters is configured for generating at least one illumination light beam. The at least one optical system includes at least one array of a plurality of transfer devices. The at least one array of the plurality of transfer devices includes at least one transfer device for each of the individual emitters. The at least one array of the plurality of transfer devices includes at least two groups of transfer devices. The transfer devices of one of the groups are configured for generating at least one illumination pattern. The transfer devices of the other group are configured for generating diverging light beams.

摘要: Disclosed herein is a light module and a method for operating the light module. The light module includes a light source; an electronic circuit for driving the light source; where the electronic circuit includes a current source, where the current source is designated for generating and controlling a control current for driving the light source, and a protection controller, where the protection controller is designated for interrupting the control current to the light source in an event in which the current source fails. The light module and the related method address an eye-safe operation of the light module, specifically for a laser light source included by the light module to achieve compliance to laser safety class 1.
