    Abstract: According to an embodiment, an information processing device is configured to: estimate, based on target image data, target position data representing an image-capturing position at which the target image data is captured; estimate, based on the target image data, target depth data representing a distance to an object from the image-capturing position; register new image-capturing information including the target image data, the target position data, and the target depth data; display, on a display device, map data representing a map of an environment in which the image data is captured; and display at least one of image data and depth data included in designated image-capturing information that is designated from among a plurality of pieces of image-capturing information, in association with a pixel position in the map data, the pixel position corresponding to position data included in the designated image-capturing information.

    Abstract: Systems, devices, and methods are provided for depth-guided structure from motion. A system may obtain a plurality of image frames from a digital content item that corresponds to a scene and determine, based at least in part on a correspondence search, a set of 2-D keypoints for the plurality of image frames. A depth estimator may be used to determine a plurality of dense depth map for the plurality of image frames. The set of 2-D keypoints and the plurality of dense depth maps may be used to determine a corresponding set of depth priors. Initialization and/or depth-regularized optimization may be performed using the keypoints and depth priors.

    Abstract: Embodiments of the present disclosure relate to an image processing method, a device and a computer-readable storage medium. The method includes obtaining a first reference image and a second reference image of a reference object. The method further includes determining a first constraint and a second constraint based on the first reference image and the second reference image. The first constraint is related to a difference between different depth maps of the same reference images, and the second constraint is related to a depth consistency of different reference images. The method further includes training a depth estimation model at least based on the first constraint and the second constraint. In this way, an obtained trained depth estimation model may provide more accurate depth information.

    Abstract: Some techniques described herein cover an image processing system that intelligently maintains certain regions of an image at a higher resolution than other regions. Such techniques can include contextual selection of a part of a field of view of a camera to perform an operation (e.g., generating or adding to a depth map) and maintaining higher resolution in one or more regions of images of the field of view that correspond to the part.
