METHOD AND APPARATUS FOR SCANNING AND PRINTING A 3D OBJECT

摘要

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 three-dimensional image of the object. The image frames may be formed into the composite image based on representing features of each image frame a set of points in a three dimensional depth map. Coordinates of the points in the depth map may be estimated with a level of certainty. The level of certainty may be used to determine which points are included in the composite image. The selected points may be smoothed and a mesh model may be formed by creating a convex hull of the selected points. The mesh model and associated texture information may be used to render a three-dimensional representation of the object on a two-dimensional display. Additional techniques include processing and formatting of the three-dimensional representation data to be printed by a three-dimensional printer so a three-dimensional model of the object may be formed.

1. A portable electronic device, comprising:
a camera; at least one processor configured to:
form a first representation of an object from a plurality of image frames acquired with the camera from a plurality of directions, the representation comprising locations in a three-dimensional space of features of the object;determine, from the first representation, a second representation of the object, the second representation comprising locations of one or more surfaces;identify, from the second representation, surfaces that are not printable in three dimensions;modify the second representation to remove the surfaces that are not printable in three dimensions; andstore the modified second representation as a three-dimensional printable file.
