Abstract
A smartphone may be freely moved in three dimensions as it captures a stream of images of an object. Multiple image frames may be captured in different orientations and distances from the object and combined into a composite image representing an image of the object. The image frames may be formed into the composite image based on representing features of each image frame as a set of points in a three dimensional point cloud. Inconsistencies between the image frames may be adjusted when projecting respective points in the point cloud into the composite image. Quality of the image frames may be improved by processing the image frames to correct errors. Distracting features, such as the finger of a user holding the object being scanned, can be replaced with background content. As the scan progresses, a direction for capturing subsequent image frames is provided to a user as a real-time feedback.
