VSD Editorial Digest: Understanding machine vision optics: An A-Z
April 10, 2012
Advances in high-resolution sensors with higher pixel densities are challenging optics manufacturers to produce lenses with increased performance. One of the greatest challenges facing system developers is determining how to properly match these lenses with high-performance cameras and how to establish the resolving power of lens/camera combinations. In this editorial digest, Greg Hollows and Stuart Singer show how lenses can limit the performance of imaging systems, highlighting the physics behind such factors as diffraction, lens aperture, focal length, and the wavelength of light. By considering their applications, resolution, illumination, depth of field (DOF) and field of view (FOV), readers will understand how to better build systems that meet their expectations. |

VSD Editorial Digest: Market Opportunity for Machine Vision in Service Robots
September 19, 2011
Service robots, which are robots serving human needs beyond the factory floor, are playing an increasingly important role in many aspects of life. These robots come in many designs and perform tasks that range from aerial surveillance, bomb disposal, farming, and warehouse logistics to teaching children and assisting the elderly. They use machinevision and image-processing components, subsystems, and technologies to image, store, and interpret data about the world around them, and perform actions based on the data. |
