Abstract
Methods and systems for determining the shape of an object based on shadows cast by the object are described. An example method may include receiving a plurality of images of an object casting a shadow. Each image may include a shadow cast by the object as the object is illuminated by a light source that moves over a plurality of positions. The method may further include determining, by a computing device, respectively for each image of the plurality of images a two-dimensional (2D) silhouette of the object and a respective position of the light source relative to the object. According to the method, a three-dimensional (3D) object data model of the object may be generated by the computing device based on the 2D silhouette of the object and the respective position of the light source relative to the object for each image of the plurality of images.
