Patent number: 11812342Abstract: A method for creating a correction function for improving the accuracy of a GPS device collects multiple time samples at multiple known locations wherein each time sample consists of GPS coordinates and associated satellite data from multiple satellites. The satellite data includes or permits determination of (i) satellite azimuth and elevation of an associated satellite, (ii) Signal-to-Noise Ratio of a received signal from the associated satellite, and optionally (iii) pseudo-range. For each time sample a respective error between the known location and the corresponding GPS coordinates is computed and an error correction function is created as a function of the respective GPS coordinates and the satellite data by applying deep learning/machine learning techniques to the multiple time samples.Type: GrantFiled: September 8, 2020Date of Patent: November 7, 2023Assignee: VEERIDE GEO LTD.Inventors: Zvi Lapidot, Ehud Tirosh

Publication number: 20220107202Abstract: A hands-free pedestrian navigation method includes mounting on a user's head (i) a display for projecting a visual image in front of the user's gaze, and (ii) an IMU, obtaining from a GPS unit carried by the user an approximate user location for locating the user in a computerized map. Confirmation is obtained from the user that the user's gaze is directed to a specified landmark in sight of the user and azimuth is computed between the user location and the landmark location extracted from the computerized map. Vocal prompts are provided and ancillary visual prompts are projected on the display to navigate the pedestrian. In a system, the user wears a head-mounted device containing the IMU and display and carries a GPS unit and a portable computing device coupled to the device and GPS unit and programmed to carry out the method.Type: ApplicationFiled: October 4, 2021Publication date: April 7, 2022Inventors: Ehud TIROSH, Zvi LAPIDOT, Shmuel FRIEDMAN

Publication number: 20220043163Abstract: A method for improving accuracy of a raw GPS positioning of an untargeted pedestrian device wherein the pedestrian device receives from a nearby vehicle device a message containing a calculated offset between a raw GPS location of the vehicle and a corrected location of the vehicle, the message being received as a direct consequence of the pedestrian device and the vehicle device coming into mutual communication range without a need for pairing between the two devices. The calculated offset is applied to the raw GPS positioning of the pedestrian device to obtain a more accurate location of the pedestrian device.Type: ApplicationFiled: August 9, 2021Publication date: February 10, 2022Applicant: VEERIDE GEO LTD.Inventors: EHUD TIROSH, ZVI LAPIDOT

Patent number: RE38716Abstract: A binary map of an object having edges is produced by first producing a digital grey scale image of the object with a given resolution, and processing the grey scale image to produce a binary map of the object at a resolution greater than said given resolution. Processing of the grey scale image includes the step of convolving the 2-dimensional digital grey scale image with a filter function related to the second derivative of a Gaussian function forming a 2-dimensional convolved image having signed values. The location of an edge in the object is achieved by finding zero crossings between adjacent oppositely signed values. Preferably, the zero crossings are achieved by an interpolation process that produces a binary bit map of the object at a resolution greater than the resolution of the grey scale image.Type: GrantFiled: June 30, 2000Date of Patent: March 22, 2005Assignee: Orbotech, Ltd.Inventors: Amiram Caspi, Zvi Lapidot
