(Stemmer Imaging: Puchheim, Germany) -- New 3-D measurement tools from Stemmer Imaging enhance the accuracy of 3-D measurements in industrial vision applications. CVB Metric 3-D and CVB Merge 3-D have been introduced to allow accurate calibration of 3-D images and to overcome potential problems in laser triangulation image acquisition resulting from shadows in the laser line. These new tools have been added to the 3-D suite of tools in the latest version (10.2) of the Common Vision Blox (CVB) programming library, which fully supports all 32-bit versions of Microsoft Windows 7.

Most common 3-D acquisition technologies don’t provide a calibrated image. Although many 3-D applications can work reliably with noncalibrated images, calibration is essential for some applications. CVB METRIC 3-D enables a 3-D space to be calibrated by measuring a defined calibration object. Once calibrated, data point area or volume can be directly measured to subpixel accuracy. To improve accuracy, the calibration can be made using the combined resultant image from CVB Merge 3-D.
