System and Method for Generating Editable Constraints for Image-based Models

摘要

An image-based 3D model of an object may be generated from multiple images of the object captured from different viewpoints. 3D constraints which define the shape of the model may be generated from image data and camera parameters (intrinsic and extrinsic) of the images and from user-specified constraints. A user may specify constraints by outlining, on images of the object, features which define the shape of an object. An approximation of the object's 3D surface may be generated from depth maps computed from the images. The 3D constraints and surface approximation may be converted into a polygonal mesh representation, from which a visual display of the model may be reconstructed. The model may be displayed with a set of editable constraints which a user may manipulate to change the shape of the 3D model. The model may be stored as, and reconstructed from, the set of 3D constraints.
