Abstract

Systems and methods for identifying the contour of an object that is depicted in an image. An object is placed on a rotating turntable and a camera, which is stationary, captures images of the object as it rotates on the turntable. In one pass, the system captures a number of photographic images that will be processed into image silhouettes. After a calibration procedure (used to determine the camera's focal length and the turntable's axis of rotation), a silhouette processing module determines a set of two-dimensional polygon shapes (silhouette contour polygons) that describe the contours of the object by comparing light intensity values in the images of the object with light intensity values from an image of the background without the object.
