Case Study: Using Edge I/O to Automate Quality Control

Mon, 25 Apr 2022 13:45:55 +0000

Intrinsics Imaging’s AI-powered vision system uses groov RIO to connect the cloud to the edge. Machine vision systems can recognize superficial aberrations in manufactured goods—like lines, spots, holes, color discrepancies, and more—that would typically require time-consuming manual inspection. California-based Intrinsics Imaging solves this problem with its Heijunka Vision analytics-as-a-service software. But when Intrinsics was approached by a…
