Line Laser Thickness and 3D Inspection

I recently implemented a project where we were using a SICK Ranger camera to measure a part. This camera works by measuring the position of light from a line generating laser on its 2D field of view and translating that to a height position. This wor...


Edmund Double-Gauss Lenses Produce Sharp Focus

I have been working on a 3D vision application using the SICK Ranger camera. My application involves precision measurement, so I want to get the best results possible from the equipment. The Ranger came with a Fujinon 35mm lens which focused shar...


Recent press releases by NASA show how the agency is realizing the advantages of using Structured Light for 3D vision. A recent NASA Invention of the Year was a hand-held, battery-operated scanner that they use to create surface maps of shuttle ti...


Matrox Introduces 3D Scanning in MIL 9

Matrox has added 3D scanning tools to the Matrix Imaging Library (MIL), version 9.0. The concept is similar to that employed in single-purpose devices by Micro-Epsilon and SICK. (see Two 3D Scanner tools.) The camera images a laser line from an ou...


New 3D Measurement Tool from IFM

I saw an amazing new 3d vision tool at the Robot and Vision Show today. It is the IFM Defector PMD 3DD. This device is a 64X48 pixel distance sensor. It operates by the time of flight principle. A pulse of light infra-red light is emitted by ...


Spotlight: Two 3D Scanner tools

Purpose-built 3D scanning tools are an exciting new development in machine vision. People have been building their own 3D scanners for years with cameras and line lasers. Now, a couple of integrated and factory-calibrated units are on the market w...
