Machine Vision FAQs
How is machine vision used in detecting defects?
Machine vision in defect detection involves using high-resolution cameras and advanced image processing algorithms to inspect products on a production line. These systems capture detailed images of products, process them to enhance quality, and extract specific features like shapes, colors, and textures.
By comparing these features against predefined standards of defect-free products, machine vision systems can accurately identify and classify any deviations, indicating potential defects.
What types of defects can machine vision systems detect?
Machine vision systems can detect a wide range of defects, including surface defects like scratches, cracks, dents, and discoloration. They are also adept at identifying dimensional inaccuracies, such as incorrect sizes or shapes, and assembly errors, including missing or misaligned components.
Additionally, machine vision can detect cosmetic defects, such as irregular textures or patterns, which might affect the product's appearance and quality.
Can machine vision systems detect defects in real-time on production lines?
Yes, machine vision systems can detect defects in real-time on production lines. These systems use high-speed cameras and image acquisition to continuously inspect products as they move along the line.
This real-time capability allows for the immediate identification and removal of defective items, ensuring minimal disruption to production.
