Abstract: A training method and device for estimating depth information of an image are disclosed. The training method may include obtaining depth information of a first image according to a resolution based on the first image, and outputting a per-pixel depth error of the first image based on the depth information of the first image, depth information of a second image, and camera parameters.

Abstract: Provided is a parallax minimization stitching method and apparatus using control points in an overlapping region. A parallax minimization stitching method may include defining a plurality of control points in an overlapping region of a first image and a second image received from a plurality of cameras, performing a first geometric correction by applying a homography to the control points, defining a plurality of patches based on the control points, and performing a second geometric correction by mapping the patches.

Abstract: A depth estimation method and apparatus using a learning model are disclosed. A depth information estimation method may include identifying a plurality of image data, generating feature maps of the plurality of image data respectively, generating a cost volume using the feature maps, generating normalized cost volumes in different sizes by normalizing the cost volume, estimating disparity information from the normalized cost volumes, and generating depth information using the estimated disparity information.
