Rapid Focal Shifting Optics for Inline 3D Image Capture

Not Accessible

Your library or personal account may give you access

Abstract

There are many visual inspection and sensing applications where both a high resolution image and a depth-map of the imaged object are desirable at high speed. Here we present a novel lens system with high-resolution and wide field-of-view for rapid 3D image capture. The design achieves this using a single lens with no moving parts. A depth-from-defocus algorithm is implemented to reconstruct 3D object point clouds and matched with a fused image to create a 3D rendered view.
