A Perspective on Range Finding Techniques for Computer Vision

Dimensional Measurement for Dentistry

“…Contact methods use mechanical contact through a trigger or scanning probe at the end of an arm or the column of a CMM (Jarvis, 1983) to obtain surface geometrical information. Development of this method was driven by reverse engineering (Milroy et al, 1996;Dalton, 1998;Chow, 1997).…”

Video-Rate Visual Servoing for Robots

“…Many techniques for depth determination exist [33], and could perhaps be categorized as static, using cues such as lighting or texture, and triangulation based where multiple views from moving cameras or stereo camera pairs are interpreted. The technique outlined here is a simple static technique based on a priori knowledge of the target object's area.…”

Multi-View Stereo: A Tutorial

“…Modeling the 3D geometry of real objects or scenes is a challenging task that has seen a variety of tools and approaches applied such as Computer Aided Design (CAD) tools [3], arm-mounted probes, active methods [110,131,11,10] and passive image-based methods [162,165,176]. Among all, passive image-based methods, the subject of this tutorial, provide a fast way of capturing accurate 3D content at a fraction of the cost of other approaches.…”
