Patent number: 11834038Abstract: An automated vehicle assistance system is provided for supervised or unsupervised vehicle movement. The system includes a control system and a first sensor system. The first sensor system may receive first image data of a scene and may output a first disparity map and a first confidence map based on the first image data. The control system may output a video stream based on the first disparity map and the first confidence map. The vehicle assistance system also may include a second sensor system that receives second image data of at least a portion of the scene that outputs a second confidence map based on second image data. The video stream may include super-frames, with each super-frame including a 2D image of the scene, a depth map corresponding to the 2D image, and a certainty map corresponding to the depth map.Type: GrantFiled: August 15, 2022Date of Patent: December 5, 2023Assignee: NODAR Inc.Inventors: Leaf Alden Jiang, Carsten Louis Boers

Publication number: 20230356743Abstract: A small-object perception system, for use in a vehicle, includes a stereo vision system that captures stereo images and outputs information identifying an object having a dimension in a range of ˜20 cm to about ˜100 cm in a perception range of ˜3 meters to ˜150 meters from the vehicle, and a system controller configured to receive output signals from the stereo vision system and to provide control signals to control a path of movement of the vehicle. The stereo vision system includes cameras separated by a baseline of ˜1 meter to ˜4 meters. The stereo vision system includes a stereo matching module configured to perform stereo matching on left and right initial images and to output a final disparity map based on a plurality of preliminary disparity maps generated from the left and right initial images, with the preliminary disparity maps having different resolutions from each other.Type: ApplicationFiled: February 3, 2023Publication date: November 9, 2023Applicant: NODAR Inc.Inventors: Jing Wang, Leaf Alden Jiang

Patent number: 11782145Abstract: An automatically calibrated vision system includes: a vision calibration system; a first sensor system that receives first data of a scene captured by a first sensor on a movable machine and outputs a first map based on the first data; a second sensor system that receives second data of the scene captured by a second sensor on the movable machine and outputs a second map based on the second data. The vision calibration system computes calibration data based on the first and second maps, supplies the calibration data to the first sensor system and/or the second sensor system for automatic calibration of the first sensor system and/or the second sensor system, and outputs, to a controller of the movable machine, a calibrated depth map comprised of depth measurements calibrated using the calibration data. The first sensor system and/or the second sensor system automatically perform(s) a self-calibration using the calibration data.Type: GrantFiled: July 19, 2022Date of Patent: October 10, 2023Assignee: NODAR Inc.Inventors: Piotr Swierczynski, Leaf Alden Jiang, Matthew Beveridge

Publication number: 20230005184Abstract: A long-baseline and long depth-range stereo vision system is provided that is suitable for use in non-rigid assemblies where relative motion between two or more cameras of the system does not degrade estimates of a depth map. The stereo vision system may include a processor that tracks camera parameters as a function of time to rectify images from the cameras even during fast and slow perturbations to camera positions. Factory calibration of the system is not needed, and manual calibration during regular operation is not needed, thus simplifying manufacturing of the system.Type: ApplicationFiled: March 14, 2022Publication date: January 5, 2023Applicant: NODAR Inc.Inventors: Leaf Alden Jiang, Philip Bradley Rosen, Piotr Swierczynski
