Abstract
An approach for automatic 3D object re-construction using its shadow is
presented. The approach investigates the use of information inherited by the
generated object shadows to re-construct the object geometry. An algorithm is
developed that make use of object height information for the directions associated
with the incident light and the generated object shadows, hence, acquired height
features represents the object features that have actually obstructed the incident
light. The technique is tested using objects of different shapes. Close to real
measurements are gained and the overall accuracy of the system is found to be
within 0.75 mm using the adopted imaging hardware and setup. Obtained results
confirmed the validity of the proposed approach.
