Explorations in Monocular Distance And Ranging (MODAR) Techniques for Real-World Applications
… a monocular camera system capable of retrieving depth-from-focus using a liquid focus-tunable lens is constructed out of hobby-grade photography equipment. This concept has been explored previously in laboratory settings using specialized equipment; this work seeks to determine the feasibility of …

Generic camera calibration for omnifocus imaging, depth estimation and a train monitoring system
… then applied as input to new algorithms in omnifocus imaging, 3D scene depth from focus and machine vision based intermodal freight train analysis. In the first prat of this dissertation, we present new progress made in the areas of camera calibration with application to omnifocus imaging and 3D …

Real-time monocular depth mapping system using variance of focal plane and pixel focus measure
… most important sensory skills creatures have is depth perception, which allows them to estimate the relative distance of objects in their vision from many visual cues. Many systems have been developed to aid machines in perceiving the depth map of their environment, and each system has its …

High Speed Instrumentation for Inspection of transparent parts
… The stream of images are processed using a depth from focus technique to provide surface inspection with 0.5 micron lateral resolution and 1 micron vertical resolution at an inspection speed of 640,000 voxels per second. The instrument also demonstrates the ability to measure vertical …
