An approach for automatic 3D object re-construction using its shadow ispresented. The approach investigates the use of information inherited by thegenerated object shadows to re-construct the object geometry. An algorithm isdeveloped that make use of object height information for the directions associatedwith the incident light and the generated object shadows, hence, acquired heightfeatures represents the object features that have actually obstructed the incidentlight. The technique is tested using objects of different shapes. Close to realmeasurements are gained and the overall accuracy of the system is found to bewithin 0.75 mm using the adopted imaging hardware and setup. Obtained resultsconfirmed the validity of the proposed approach.
