Multi‐Aperture Telecentric Lens

A multi‐aperture telecentric lens is a single telecentric lens with multiple aperture stops that provides images with constant magnification and precise 3‐D measurement capability. This entry first describes the conventional telecentric lens. The configurations of a multi‐aperture telecentric lens are then presented, after which the advantages of a multi‐aperture telecentric system with respect to the conventional stereo vision systems are discussed. A geometric model for 3‐D reconstruction using a multi‐aperture telecentric lens is presented, and camera calibration and image matching in multi‐aperture telecentric systems are also discussed. Based on the geometric model, a theoretical analysis of the potential accuracy of a multi‐aperture telecentric system used in 3‐D reconstruction is conducted. Finally, several future research directions related to the multi‐aperture telecentric lens are suggested.
