Rollout photography systems and methods for mobile devices
Systems and techniques are described herein for rollout photography for mobile devices. For example, a computing device (e.g., a mobile device) can obtain, from a camera, a plurality of image frames of an object while at least one of the apparatus or the object is moving relative to each other. The computing device can determine a plurality of image segments from the plurality of image frames of the object. The plurality of image segments include a respective image segment from each image frame of the plurality of image frames. The computing device can combine the plurality of image segments to generate a single two-dimensional (2D) image of a surface of the object.
