One of the most important functions of any machine-vision system is pattern matching. In vision-guided robotics, for example, pattern-matching algorithms are widely used in pick...
In many machine-vision systems for dimensional metrology, laser lines are used to provide structured illumination—allowing height to be estimated through triangulation using the...
A number of different methods exist to generate 3-D image data. These include structured laser light-based systems, time-of-flight (TOF)-based methods, and projected structured...
Metrology consulting firm Pine Falls Technical Services has shown the Royal Canadian Mounted Police (RCMP) and the Winnipeg Police Department how a laser-based imaging device ...
Jason Fleischer and his colleagues at Princeton University’s Nonlinear Photonics Group are developing an imaging technique that relies on a nonlinear crystal rather than a standard...
In surveillance, a user-friendly and robust automated object detection and tracking system that can handle complex situations is not yet available. Recently, Oliver Sidla and ...
Researchers at Carnegie Mellon University’s National Robotics Engineering Center have developed a plant-sorting machine that uses machine vision and image processing. The machine...
A simpler camera with embedded intelligence sounds like a good idea for machine vision. In fact, as editor Andy Wilson writes in his My View column in this issue, many vendors...
