Visual inspection solutions
It is typical to carry out visual inspection using human vision, but there is variation in worker judgment, and workers ofter miss anomalies.
This also places a heavy burden on evaluators, and inspection speed cannot be increased.
Previous rule-based image inspection is capable of high-speed high-volume processing. However, it is extremely difficult to set parameters with an understanding of rules for all anomalous conditions, and cases of missing anomalies tend to occur easily.
Unlike previous rule-based image processing, our ADFI uses a web application to provide the latest AI technology enabling high-precision anomaly detection with easy parameter setting.
- No complex parameter setting needed
- Inspection threshold can be changed with one click
What’s ADFI?
ADFI is anomaly detection and visual inspection system which operates on the cloud, and is equipped with state-of-the-art AI algorithms.
It allows you to adopt an AI anomaly detection and visual inspection system in a short time, simply by providing a few dozen images.
You can also check detection precision beforehand through a free trial.
You can select either of two algorithms (Deep Metric Learning or PCA-MSPC) as the AI to be used, whichever best suits the characteristics of the items to be inspected and detected.
DML
DML (Deep Metric Learning) is a new deep learning technique suited to anomaly detection.
It enables anomaly detection even for problems that are difficult to handle with conventional anomaly detection technology (e.g., cases where the position of the inspected object is not fixed).
ADFI uses a unique algorithm which improves conventional DML, and no specialized knowledge is needed because optimization can be performed through automatic parameter adjustment.
Features
- High general applicability (no limitations on the position or shape of inspected object)
- Time needed for learning is short (10–60 minutes)
- Parameters can be optimized automatically
- No need for specialized knowledge of AI or anomaly detection
Conditions
- Requires at least 20 images (recommended: at least 50) of normal data and at least 5 images (recommended: at least 10 images) of anomalous data for learning
PCA-MSPC
PCA-MSPC (Multivariate Statistical Process Control based on Principal Component Analysis) is an anomaly detection technique currently in wide use in fields such as manufacturing industries.
This AI algorithm is suitable for situations where the position of the inspected object is fixed inside the image.
ADFI uses a unique algorithm which improves conventional PCA-MSPC, and no specialized knowledge is needed because optimization can be achieved through automatic parameter adjustment.
Features
- Learning can be done with normal data only (no need to provide anomalous data)
- Time needed for learning is extremely short (10–30 seconds)
- Parameters can be optimized automatically
- No need for specialized knowledge of AI or anomaly detection
Conditions
- Position and shape of inspected object must be fixed
- Requires at least 10 images (recommended: 30 or more) of normal data for learning

Cutting-edge AI technology
ADFI enables development of high-performance visual inspection systems with a small amount of learning data.
Furthermore, anomalies can be detected with higher inspection precision than previous visual inspection algorithms, and this reduces release of defective items and time spent on reinspection.
There is no need to procure servers or edge computers, or purchase expensive AI visual inspection software. You can quickly adopt AI visual inspection by using the ADFI web application on the cloud. Initial cost is low, and fees are set according to usage, so a system can be operated at low cost.
- AI visual inspection can be adopted without the need for any specialized equipment.
- Anomalies can be detected at high precision.
- You can build a new visual inspection system in as little as 1 day.
- Enables a dramatic reduction in cost of adopting visual inspection.
No need for servers
High detection rate
Easy setup
Low cost
System composition
ADFI is provided on the AWS cloud, and thus can be used by connecting to the Internet.
Communication is done via HTTPS, so the ADFI API can be used safely.
When an image is sent to the ADFI API from a control PC or PLC in a production process, the inspection result is returned in real-time.
Adoption process
You can do a trial on the same day. The process up to operation can be completed in as little as 1 day.
