Sound Practices for Consistent Human Visual Inspection

Looking for inspection improvements through base practices

Inspection process improvement is typically a non-rational process, in which the improvement suggestions come from randomly arranged brainstorming meetings. The improvement ideas focus mainly on updating of checklists, adoption of new forms and definition of new metrics for measurement data. These are important and usually the most relevant improvement topics, but we should strive for a more ri...

User Programmable Visual Inspection

The usefulness of advanced machine vision techniques for automated inspection is restricted by long development cycles for the inspection software and a lack of general applicability of the resulting system. These difficulties arise because in the majority of cases the particulars of the inspection are embedded in the software structure resulting in severe restrictions on user reconfiguration. ...

Automatic Visual Inspection System for Tape Carrier Package Using Unique Image Processing and Human Visual Support

An automatic visual inspection system for the Tape Carrier Package (TCP) has been developed. To achieve low cost implementation and high speed inspection, we integrated unique image processing (0.7secldevice) to screen TCP devices which appear to be defective, with multiple illuminations to enhance defect images and a human interface for operators to finally judge the quality of the TCP. The op...

Adaptive Visual Inspection

The robot vision system A prototype robotized vision system has been designed, using a six degrees of freedom anthropomorphic arm, for self-adaptive vision based quality control on an assembly line for washing machines (WM). The robot allows displacing the camera in the workspace so to inspect a washing unit (WU) or a complete WM on a pallet. The vision system is equipped with a 1360x1024 pixel...
