| 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. | ||
