• While human inspectors working on assembly lines visually inspect parts to judge the quality of workmanship, machine vision systems use cameras and image processing software to perform similar inspections. Machine Vision inspection plays an important role in achieving 100% quality control in manufacturing, reducing costs and ensuring a high level of customer satisfaction.

• Machine vision system inspection consists of narrowly defined tasks such as counting objects on a conveyor, reading serial numbers, and searching for surface defects. Manufacturers often prefer machine vision systems for visual inspections that require high speed, high magnification, around-the-clock operation, and/or repeatability of measurements. Machine vision is the automated extraction of useful information from digital images in an industrial setting.

Examples of useful information:

• Confirmation of fill level
• Confirmation that all components are assembled correctly
• Part location and orientation for robot pickup
• Part identification reading human or machine readable codes

Quality Assurance

• Fewer rejects
• Automatic visual inspection: Objective, fact and reliable: Checks dimensional tolerances and shapes, detects whether parts are absent, checks correct mounting, position and completeness of parts, which can even be microscopically small (e.g. chip structures)
