Abstract

With a partially calibrated stereo or shape from unknown motion method, the reconstruction of an object can be performed but at most up to a scale factor. Therefore, metric measurements of the 3D features cannot be achieved. This paper proposes a method to enable metric measurements of the 3D features starting from 3D length measurement by moving camera. The best focused location in an image is used as a cue in upgrading the relative geometry of a target feature into an absolute one. Hence, we can obtain dimension and metric sizes of object features.
