TR-300

  • Official site

Without stopping, view in 3D. We inspect while 3D-visualizing the surface along the moving line.

The TR-300 is an appearance inspection system that inspects surfaces in 3D while continuously flowing along the line. The workpiece is kept in motion while the device captures images using a line scanning method. Using the unique technology "FORESIGHT STEREO," which obtains surface normals that are less affected by lighting from multi-directional illumination, it captures the orientation of surfaces rather than colors or patterns. Printing and dirt patterns disappear, leaving only the shapes of defects such as dents. The obtained 3D information is passed to the AI anomaly detection engine "E3 ENGINE," which determines quality based solely on learning from good products. It has received the "Future Creation Award" at the 40th Kanagawa Industrial Technology Development Awards and the "Encouragement Award" at the 38th Excellent New Technology/New Product Awards for Small and Medium Enterprises.

40th Kanagawa Industrial Technology Development Award Ceremony

The Kanagawa Prefectural Governor's blog "Kuroiwa Diary" features the ceremony for the 40th Kanagawa Industrial Technology Development Award.

  • NEW
  • Company news

The award ceremony for the "40th Kanagawa Industrial Technology Development Award," held on December 25, 2025, was featured on the official blog "Kuroiwa Diary" of Kanagawa Prefectural Governor Yuji Kuroiwa. Our company received the "Future Creation Award" for our 3D×AI visual inspection system "TR-300" at this award ceremony. We perceive our efforts as being recognized as part of Kanagawa Prefecture's industrial technology. Moving forward, we will implement our research results as technologies that create value in manufacturing sites, not just limited to proof of concept (PoC).

38th Small and Medium Enterprises Excellent New Technology and New Product Award Encouragement Prize

The "TR-300," which detects fine scratches on glossy materials with flowing lines, has received the Encouragement Award at the 38th Small and Medium Enterprises Excellent New Technology and New Product Awards.

  • NEW
  • Company news

Our high-speed, continuous AI visual inspection system "TR-300" has received an Encouragement Award at the 38th "Small and Medium Enterprises Excellent New Technology and New Product Award" (organized by the Resona Foundation for Small and Medium Enterprises Promotion, co-organized by Nikkan Kogyo Shimbun). It was also featured in the Nikkan Kogyo Shimbun on April 15, 2026. The TR-300 is a visual inspection system that synchronously controls multiple line-type LED lights to capture fine surface irregularities in three dimensions and uses AI to determine defects. The inspection results are displayed as a heatmap. It can inspect glossy materials where defects are difficult to see under normal lighting without stopping the production line. ■ Intended applications: Steel plate forming processes, automotive parts, sheet and film work such as laminated films, textiles, and paper products. ■ Points of evaluation: Uniqueness of technology integration, practical level of completeness, and adaptability to challenges in manufacturing sites (labor shortages, variability in inspections, difficulty with glossy materials). The TR-300 has also received the "Future Creation Award" at the 40th Kanagawa Industrial Technology Development Award.

Imaging Report: Scale Patterns on Steel Plates (TR-300)

[Image Report Release] Distinguishing linear defects and dents hidden in the scale patterns of steel plates using TR-300.

  • NEW
  • Product news

We have compiled a report on the results of imaging the steel plate sample entrusted to us by the customer using the 3D×AI visual inspection system "TR-300." The steel plate, covered with black scale patterns, has three linear scratches and two dents hidden beneath. When comparing the normal image (LIVE) obtained from a single imaging session with the extracted 3D Surface, we found that: - The contrast of the pattern decreased from 66.4% to 0.2% (since the pattern is color and not topography). - Shallow scratches that were almost invisible in the LIVE image appeared as two lines in the 3D Surface. On the other hand, the scratches where the base metal was exposed were clearer in the LIVE image. The TR-300's feature is that it allows for the verification of both color-visible scratches and shape-visible scratches with two aligned images. Comparison data and images of the five scratches can be viewed in the related catalog (imaging report).

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.
