A robotic 3D vision system for automatic cranial prostheses inspection

Abstract

The goal of this research work was to create a prototype of a robotic 3D vision system for cranial prostheses automatic inspection. The proposed device is able to automatically scan the entire prosthesis under study by means of an automatic tilt-rotational mechanism and the embedded software allows to generate an automatic inspection report by comparing the specimen with a reference digital sample. The output of the procedure gives information about the geometrical conformity of the new fabricated prosthesis and automatically accept or discard the product. The presented prototype is the first one in literature to have such an automated quality control and rejection procedure in 3D vision and it is also the first robotic vision system applied to cranial prosthesis manufacturing.
