Claim One:
1. A method for registering points with planes, wherein the points and planes are three-dimensional and associated with an object, wherein the points are acquired by a sensor and represented in a sensor coordinate system and the planes are provided by a 3D model of the object in a world coordinate system, comprising the steps of: determining correspondences between the points and the planes; transforming, using the correspondences and transformation parameters, the points from the sensor coordinate system to an intermediate sensor coordinate system using sensor rotation and translation parameters (R s , T s ) such that three points (P 1 , P 2 , P 3 ) are respectively at an origin, at an X axis and in an XY plane of the intermediate sensor coordinate system; transforming, using the correspondences, the planes to an intermediate world coordinate system using world rotation and translation parameters (R w , T w ), such that a plane Π 1 is in an XY plane, and a plane Π 2 intersects an X axis of the intermediate world coordinate system; determining intermediate rotation and translation parameters (R, T) by applying coplanarity constraints and orthogonality constraints to the points in the intermediate sensor coordinate system and the planes in the intermediate world coordinate system; and determining rotation and translation parameters (R s2w , T s2w ) between the sensor and world coordinate systems using (R s , T s ), (R w , T w ), and (R, T) to register the points with the planes, wherein the steps are performed in a processor.
