Patent number: 11127158Abstract: The present embodiments relate to automatically estimating a three-dimensional pose of an object from an image captured using a camera with a structured light sensor. By way of introduction, the present embodiments described below include apparatuses and methods for training a system for and estimating a pose of an object from a test image. Training and test images are sampled to generate local image patches. Features are extracted from the local image patches to generate feature databased used to estimate nearest neighbor poses for each local image patch. The closest nearest neighbor pose to the test image is selected as the estimated three-dimensional pose.Type: GrantFiled: February 23, 2017Date of Patent: September 21, 2021Assignee: Siemens Mobility GmbHInventors: Srikrishna Karanam, Ziyan Wu, Shanhui Sun, Oliver Lehmann, Stefan Kluckner, Terrence Chen, Jan Ernst

Patent number: 10699438Abstract: The present embodiments relate to localizing a mobile device in a complex, three-dimensional scene. By way of introduction, the present embodiments described below include apparatuses and methods for using multiple, independent pose estimations to increase the accuracy of a single, resulting pose estimation. The present embodiments increase the amount of input data by windowing a single depth image, using multiple depth images from the same sensor, and/or using multiple depth image from different sensors. The resulting pose estimation uses the input data with a multi-window model, a multi-shot model, a multi-sensor model, or a combination thereof to accurately estimate the pose of a mobile device.Type: GrantFiled: July 6, 2017Date of Patent: June 30, 2020Assignee: Siemens Healthcare GmbHInventors: Oliver Lehmann, Stefan Kluckner, Terrence Chen

Publication number: 20200057778Abstract: In pose estimation from a depth sensor (12), depth information is matched (70) with 3D information. Depending on the shape captured in depth image information, different objects may benefit from more or less pose density from different perspectives. The database (48) is created by bootstrap aggregation (64). Possible additional poses are tested (70) for nearest neighbors already in the database (48). Where the nearest neighbor is far, then the additional pose is added (72). Where the nearest neighbor is not far, then the additional pose is not added. The resulting database (48) includes entries for poses to distinguish the pose without overpopulation. The database (48) is indexed and used to efficiently determine pose from a depth camera (12) of a given captured image.Type: ApplicationFiled: April 11, 2017Publication date: February 20, 2020Inventors: Shanhui Sun, Stefan Kluckner, Ziyan Wu, Oliver Lehmann, Jan Ernst, Terrence Chen
