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...


Solution to VB and VBA problems using the FlexGrid

Earlier in 2009, Microsoft declared the old FlexGrid control that came with VB6 a security threat. A security patch banned its use. FlexGrid was an ActiveX control that was commonly distributed with many applications including Office. It has been ...


Reliable alternate for slow or unreliable DNS

My ISP at home, WOW, has started filtering DNS lookups and redirecting unresolvable names to their own search site. I found a lengthy discussion of this issue here. Basically, if you misspell something, a Yahoo search results, and they must be gettin...


In the beginning, all of the important files at DMC fit onto a single 100MB iomega ZIP disk. Since 1996 we have grown to a 25 person company and gone from 0 servers to 6. We used BackupExec for a couple years but then switched to Dantz Retrospect for...


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...


Using FBVEL Gain for PID Servo motion tuning Acroloop

I have been using Acroloop 9000 controllers to control a number of machines where one axis is a high-speed rotary motor that drives a mechanical cam-driven process. During operation of the machine, the motor accelerates from a stop to a constant high...


At DMC we make heavy use of Microsoft SharePoint in almost everything we do from project management to financial tracking. We use Excel Services to display real time key performance indicators. Several of us in the office have recently updated to ...


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...
