Abstract
What is disclosed a system and method for estimating a position (or pose) of a camera relative to a surface upon which an object rests in an image captured by that camera such that a volume can be estimated for that object. In one embodiment, a matrix K is determined from parameters intrinsic to a camera used to capture image. An amount of a camera translation T is determined with respect to a set of real-world coordinates in (X,Y,Z). An amount of a camera rotation matrix R is determined from camera angles measured with respect to the real-world coordinates. A distance Zc of the camera at location (i,j) can then be estimated. A volume of the object in an image of that object can be estimated from the camera pose.
