Publication number: 20230324543Abstract: Creating and updating an accurate radar map layer for HD map using crowdsourcing may comprise a vehicle obtaining radar data and filtering the radar data on a frame-by-frame basis. In some embodiments, additional filtering may be made on a batch of frames. The vehicle can then transmit the filtered radar data responsive to a determination that a confidence of a position estimate of the vehicle exceeds a conference threshold level and/or a determination that a reliance of the position estimate of the vehicle on the radar data exceeds a reliance threshold level.Type: ApplicationFiled: April 8, 2022Publication date: October 12, 2023Inventors: Mandar Narsinh KULKARNI, Jubin JOSE, Muryong KIM

Patent number: 11636693Abstract: Association algorithms of newly-detected lane boundaries to lane boundaries can be made more robust through the use of generated or “dummy” states. Different types of dummy states can be used to identify outlier/erroneous detections and/or new, legitimate lane boundaries. Therefore, depending on a type of dummy state a newly-detected lane boundary is associated with, the newly-detected lane boundary can be ignored, or the associated dummy state can be added to the lane boundary states of the filter.Type: GrantFiled: January 20, 2021Date of Patent: April 25, 2023Assignee: QUALCOMM IncorporatedInventors: Urs Niesen, Muryong Kim, Jubin Jose

Patent number: 11227168Abstract: To make error correction in a position estimate of a vehicle, visual lane markings on the road can be matched with lane boundaries for the road within 3-D map data. Embodiments include obtaining a “stripe” indicative of an observed lane marking captured in a from a camera image, obtaining map data for the road on which the vehicle is located, determining the plane of the road from coordinates of lane boundaries within the map data, projecting the stripe onto the plane, and comparing the projected stripe with lane boundaries within the map data and associating the visual lane markings with the closest lane boundary. Differences between the projected stripe and the associated lane boundary can then be used for error correction in the position estimate of the vehicle.Type: GrantFiled: December 16, 2019Date of Patent: January 18, 2022Assignee: QUALCOMM IncorporatedInventors: Tianheng Wang, Muryong Kim, Jubin Jose

Publication number: 20200217667Abstract: Techniques provide for accurately matching traffic signs observed in camera images with traffic sign data from 3D maps, which can allow for error correction in a position estimate of a vehicle based on differences in the location of the observed traffic sign and the location of the traffic sign based on 3D map data. Embodiments include preparing the data to allow for comparison between observed and map traffic sign data, conducting the comparison in a 2D frame (e.g., in the frame of the camera image) to make an initial order of proximity of candidate traffic signs in the map traffic sign data to the observed traffic sign, conducting a second comparison in a 3D frame (e.g. the frame of the 3D map) to determine an association based on the closest match, and using the association to perform error correction.Type: ApplicationFiled: October 30, 2019Publication date: July 9, 2020Inventors: Muryong KIM, Tianheng WANG, Jubin JOSE

Publication number: 20200217972Abstract: A method for vehicle positioning may include determining a first 6 degrees of freedom (6-DOF) pose of a vehicle, wherein the first 6-DOF pose may comprise a first altitude and one or more first rotational parameters indicative of a first orientation of the vehicle relative to a reference frame. A lane plane associated with a roadway being travelled by the vehicle may be determined based on the first 6-DOF pose and lane-boundary marker locations of lane-boundary markers on the roadway. For each lane-boundary marker, the corresponding lane-boundary marker location may be determined from a map, which may be based on the reference frame. A corrected altitude of the vehicle may then be determined based on the lane plane. A corrected 6-DOF pose of the vehicle may be determined based on the corrected altitude of the vehicle, the first 6-DOF pose, and an axis normal to the lane plane.Type: ApplicationFiled: December 24, 2019Publication date: July 9, 2020Inventors: Muryong KIM, Tianheng WANG, Suraj SWAMI, Jubin JOSE

Publication number: 20200218905Abstract: Techniques provided herein are directed toward tracking lateral and longitudinal offsets, which can include positioning errors of an initial position estimate as well as inconsistencies between the map and global frames. Tracking lateral and longitudinal offsets in this manner have been shown to help increase the accuracy of subsequent position estimates of a position estimation system for vehicle that uses an initial position estimate based on GNSS and VIO, with error correction based on location data for observed visual features obtained from a map.Type: ApplicationFiled: October 31, 2019Publication date: July 9, 2020Inventors: Tianheng WANG, Muryong KIM, Jubin JOSE
