Optical Distance-Measuring Device

Номер: US20120002188A1
Принадлежит: Dr Johannes Heidenhain GmbH

An optical distance-measuring device includes a light source and an interferometer unit having a measuring retroreflector, a stationary reference retroreflector, a beam-splitter element, a beam-recombiner unit and a detection unit. The beam of rays emitted by the light source is able to swivel about the center of the reference retroreflector. The beam of rays arriving from the light source is split via the beam-splitter element into at least one measuring beam of rays and one reference beam of rays. The at least one measuring beam of rays propagates in the direction of the measuring retroreflector, and the reference beam of rays propagates collinearly with respect to the measuring beam of rays in the direction of the reference retroreflector. The measuring beam of rays is reflected back by the measuring retroreflector and the reference beam of rays is reflected back by the reference retroreflector in the direction of the beam-recombiner unit, the measuring beam of rays traveling symmetrically relative to the reference retroreflector prior to and after reflection at the measuring retroreflector. The beam-recombiner unit brings the measuring beam of rays and the reference beam of rays to interference. Distance-dependent interference signals are ascertainable via the detection unit.

Described herein are methods and systems for tracking a pose of one or more objects represented in a scene. A sensor captures a plurality of scans of objects in a scene, each scan comprising a color and depth frame. A computing device receives a first one of the scans, determines two-dimensional feature points of the objects using the color and depth frame, and retrieves a key frame from a database that stores key frames of the objects in the scene, each key frame comprising map points. The computing device matches the 2D feature points with the map points, and generates a current pose of the objects in the color and depth frame using the matched 2D feature points. The computing device inserts the color and depth frame into the database as a new key frame, and tracks the pose of the objects in the scene across the scans.

REAL TIME CALIBRATION FOR TIME-OF-FLIGHT DEPTH MEASUREMENT

Номер: US20210004975A1
Принадлежит: Magic Leap, Inc.

A method for determining a distance to a target object includes transmitting light pulses to illuminate the target object and sensing, in a first region of a light-sensitive pixel array, light provided from an optical feedback device that receives a portion of the transmitted light pulses. The feedback optical device includes a preset reference depth. The method includes calibrating time-of-flight (TOF) depth measurement reference information based on the sensed light in the first region of the pixel array. The method further includes sensing, in a second region of the light-sensitive pixel array, light reflected from the target object from the transmitted light pulses. The distance of the target object is determined based on the sensed reflected light and the calibrated TOF measurement reference information. 1. (canceled)2.

Multifunctional micro sensor system

Номер: US20160006505A1
Принадлежит: ELMOS SEMICONDUCTOR SE

A measurement device relates to a Halios system for measuring an optical transmission path, in which at least one receiver and a compensation transmitter are optically separated from each other by an optical barrier in such a matter that a direct irradiation of said receiver by said compensation transmitter is not possible. Said compensation transmitter and a transmitter are of the same type and/or have at least a common electric optical working point in an optical working point. Said optical barrier has a compensation path, characterized by a compensation window, which attenuates the light of the compensation transmitter before it hits the receiver in such a manner that the compensation transmitter and said transmitter are operated at least in an optical working point by a controller in said identical electro-optical working point.
