Patent number: 12169943Abstract: Depth information is extracted from a stereoscopic image pait by an image processing system. For each pixel of a target image of the stereoscopic image pair, a final disparity cost vector is computed having cost components corresponding to different disparities. The final disparity cost vector is stored in association with that pixel. That pixel is assigned the disparity corresponding to the lowest cost component of the final disparity cost vector, wherein the extracted depth information comprises the disparities assigned to the pixels of the target image. For at least a subset of the pixels of the target image, the final disparity cost vector is computed for each of those pixels by computing, with respect to the reference image, a set of matching costs for that pixel and the different disparities, and combining the matching costs with the one or more final disparity cost vectors stored in association with one or more of the adjacent pixels of the target image.Type: GrantFiled: May 3, 2019Date of Patent: December 17, 2024Assignee: Five AI LimitedInventor: Oscar Rahnama

Patent number: 11122186Abstract: An image pickup device includes a first camera, a second camera, a first image signal processor (ISP) and a second ISP. The first camera obtains a first image of an object. The second camera obtains a second image of the object. The first ISP performs a first auto focusing (AF), a first auto white balancing (AWB) and a first auto exposing (AE) for the first camera based on a first region-of-interest (ROI) in the first image, and obtains a first distance between the object and the first camera based on a result of the first AF. The second ISP calculates first disparity information associated with the first and second images based on the first distance, moves a second ROI in the second image based on the first disparity information, and performs a second AF, a second AWB and a second AE for the second camera based on the moved second ROI.Type: GrantFiled: November 8, 2019Date of Patent: September 14, 2021Assignee: Samsung Electronics Co., Ltd.Inventor: Duck-Soo Kim

Patent number: 10977818Abstract: A method for deriving an image sensor's 3D pose estimate from a 2D scene image input includes at least one Machine Learning algorithm trained a priori to generate a 3D depth map estimate from the 2D image input, which is used in conjunction with physical attributes of the source imaging device to make an accurate estimate of the imaging device 3D location and orientation relative to the 3D content of the imaged scene. The system may optionally employ additional Machine Learning algorithms to recognize objects within the scene to further infer contextual information about the scene, such as the image sensor pose estimate relative to the floor plane or the gravity vector. The resultant refined imaging device localization data can be applied to static (picture) or dynamic (video), 2D or 3D images, and is useful in many applications, most specifically for the purposes of improving the realism and accuracy of primarily static, but also dynamic Augmented Reality (AR) applications.Type: GrantFiled: February 23, 2018Date of Patent: April 13, 2021Assignee: Manor Financial, Inc.Inventors: Taylor Clark, Andrew Kemendo, Mark Shanks
