Vision Systems for 3D Measurement Require Care to Ensure Alignment

Facebook Twitter LinkedIn Email
JESSICA GEHLHAR, EDMUND OPTICS INC.

Calibration, pointing accuracy, and repeatability are critical to the success of vision systems for measurement. This is especially true for precise 3D multicamera measurement applications where single-pixel measurements are needed to help machine vision systems accurately gauge their environment. Even the smallest misalignment between optics and the components holding them in place will significantly affect the repeatability of 3D measurements. Small, low-cost sensors and lenses and the ability to capture and store a lot of data have significantly contributed to the growth of 3D...Read full article
