9 Hardware and Algorithm Fixes for Failing Machine Vision Detection Accuracy
Industrial machine vision systems often perform well in lab settings but suffer accuracy drops after deployment on production lines, with causes spanning hardware and software layers. A two-part technical guide outlines nine troubleshooting directions drawn from real project experience, with Part 1 covering six hardware and physical-environment factors. Camera resolution is identified as a foundational issue, with the industry rule requiring pixel accuracy to be no greater than one-eighth of the inspection tolerance. Shutter type is another critical hardware choice, as rolling-shutter cameras produce image distortion on fast-moving objects — known as the jelly effect — making global-shutter sensors the standard for dynamic industrial inspection. The guide advises engineers to audit pixel accuracy calculations and verify shutter compatibility before adjusting algorithm parameters.
