Publication number: 20220012847Abstract: A virtual shockwave creation system comprises an eyewear device that includes a frame, a temple connected to a lateral side of the frame, and a depth-capturing camera. Execution of programming by a processor configures the virtual shockwave creation system to generate, for each of multiple initial depth images, a respective shockwave image by applying a transformation function to the initial three-dimensional coordinates. The virtual shockwave creation system creates a warped shockwave video including a sequence of the generated warped shockwave images. The virtual shockwave creation system presents, via an image display, the warped shockwave video.Type: ApplicationFiled: September 27, 2021Publication date: January 13, 2022Inventors: Sagi KATZ, Eyal ZAK

Publication number: 20210201520Abstract: Various embodiments provide systems, methods, devices, and instructions for performing simultaneous localization and mapping (SLAM) that involve initializing a SLAM process using images from as few as two different poses of a camera within a physical environment. Some embodiments may achieve this by disregarding errors in matching corresponding features depicted in image frames captured by an image sensor of a mobile computing device, and by updating the SLAM process in a way that causes the minimization process to converge to global minima rather than fall into a local minimum.Type: ApplicationFiled: March 12, 2021Publication date: July 1, 2021Inventors: David Ben Ezra, Eyal Zak, Ozi Egri

Publication number: 20200413030Abstract: Three-dimensional image calibration and presentation for stereoscopic imaging systems such as eyewear including a first camera and a second camera is described. The calibration and presentation includes obtaining a calibration offset using vanishing points obtained from images captured by a first camera and a second camera to accommodate rotation of the first and second cameras with respect to one another, adjusting a three-dimensional rendering offset by the obtained calibration offset, and presenting the stereoscopic images using the three dimension rendering offset.Type: ApplicationFiled: May 29, 2020Publication date: December 31, 2020Inventors: Eyal Zak, Sagi Katz
