An AI anomaly detection engine that learns only from good products and returns three values: OK / Human_Check / NG.
The E3 ENGINE is an AI anomaly detection engine for visual inspection that learns only from images of good products and quantifies the deviation from good products for judgment. The judgment results are returned as three values: OK / Human_Check / NG. Areas where judgment is unclear are sent back to humans, allowing for a reduction in the burden on inspectors while maintaining numerical criteria for evaluation rather than relying entirely on AI. Even at a stage where defective product samples have not been collected, PoC can be started from good product images. By combining it with the unique 3D imaging technology "FORESIGHT STEREO," it can also evaluate defects such as scratches on glossy surfaces that are difficult to capture under normal lighting. Adding and updating product varieties is also easy.

basic information
■Learning: Only good product images ■Output: Three values of OK / Human_Check / NG, abnormal score, and heatmap display of abnormal areas ■Input: Can select normal images or outputs from FORESIGHT STEREO (such as Surface Normal) ■Operation: Operated via GUI ■Equipped Products: TR-100, TR-300 ■Note: Calibration of the threshold requires examples of defective products. The engine performs quality judgment but does not classify types of defects.

Applications/Examples of results
■Detection of dents on metal washers (trained with 50 images of good products) ■Scratch inspection on glossy surfaces (combined with FORESIGHT STEREO's 3D Surface) ■Scratch inspection on enamel wires ■Proof of Concept (PoC) at stages with few defective product samples, such as before mass production Implementation flow: Inquiry → Free diagnosis (imaging customer samples) → Proposal and cost estimation → Short-term PoC (a few days to 2 weeks) → Full implementation → Technical support

Company information
TOMOMI RESEARCH develops and provides visual inspection systems built on two core technologies: FORESIGHT STEREO, our proprietary 3D imaging technology that measures surface normals as a physical quantity independent of lighting, and E3 ENGINE, an AI anomaly detection engine trained on good products only. Measured, not estimated. By capturing surface orientation with multi-directional lighting, we suppress specular reflection and reveal shallow scratches and subtle unevenness, even on mirror-like and glossy surfaces. E3 ENGINE quantifies how far each part deviates from good products and returns one of three results: OK, Human_Check, or NG. Uncertain cases are passed back to a human inspector, so you keep numerical inspection criteria while reducing the burden on inspectors. Adding or updating product types is easy. Our lineup includes the TR-300, which inspects parts while creating 3D data on a moving line (winner of the Future Creation Award at the 40th Kanagawa Industrial Technology Development Awards and the Encouragement Award at the 38th Excellent New Technology and New Product Awards for SMEs), and the TR-100 for parts placed for inspection, so you can choose equipment that fits your process. We also offer sample imaging and inspection trials. Please feel free to contact us.
