Enabling 3D Vision

May 1, 2006 By: Barbara G. Goode, Sensors Sensors

High-end machine vision applications are progressing from 2D to 3D imaging with techniques such as laser triangulation and stereovision, say analysts at Frost & Sullivan. The 3D image sensor chips are emerging as cost-effective alternatives to weight sensors, for example, in automotive applications. Frost & Sullivan points out that SICK IVP of Sweden has introduced a laser triangulation-based "first-of-its-kind 3D vision smart camera" that also incorporates tools to estimate height and volume. The firm says the technology "is set to make a significant impact on robotic guidance applications such as bin picking, inspection of connector pins, and inspection of weld seams." (
