Product Overview: How does our Visual Quality Inspection work?

The processing flow for automated visual inspection.

Software

The main requirement for AVI is the software layer, which at its core is the computer vision technology that helps inspect products or any object of interest for defects and absence/presence of certain parts.

 

The software part of an automated visual inspection system requires advanced image analysis algorithms and heavy programming. These algorithms process images to adjust their quality, locate interesting points and regions, and, finally decide based on the features found in these regions.

 

Deep learning technologies have enabled automated visual inspection systems that outperform human or traditional machine vision processes

Deep learning models have proved to be indispensable part of the software owing to the huge success that they have shown in solving inspection problems. They can be trained on thousands of images of, say, bolts, a deep-learning algorithm gradually learns to detect any meaningful deviations from the “standard” appearance of a bolt. Depending on your use case, your inspection problem could be solved using one or a combination of different tasks like Object Detection, Semantic Segmentation and Image Classification. It could also involve OCR models to read serial numbers or barcodes.

 

how to decide on automated visual inspection system

In order to maintain high image processing speeds, a trained deep learning model has to be generally deployed on high resource computers. For instance, a GPU is necessary to get results in real time.

 

Cost of automation – robot prices and labor compensation in manufacturing

Several factors play a role in the resultant accuracy and performance of the inspection model – lighting conditions, the number of products to inspect, types of defects to look for, size of the defects/objects, the resolution of the image to name a few. An automated visual inspection system thus requires a team of skilled R&D engineers capable of building such complex systems.

 

Each manufacturing unit has different and often unique data(images) – these could be because of the a different camera type, indoor illumination or the product itself. Therefore, the software part of AVI, is always a custom solution tailored to the specific inspection needs.
