Yoga Mat and Exercise Mat Inspection
Yoga mat and sports mat inspection: for TPE, EVA and rubber yoga mats and sports mats, inline imaging + AI segmentation of foam sheets for stains, foreign matter, damage, print misalignment and dimensions, outputting OK/NG.
Application Overview
Defect inspection of foamed sheets for yoga mats and exercise mats
Inspection of stains, foreign matter, damage, pattern misalignment and dimensions on the surface of yoga mats / sports mats (TPE / EVA / rubber foam); foam sheet is imaged inline, with AI judging defects and measuring.
Yoga mats / sports mats are foamed sheet material with texture and printing on the surface, where stains, foreign matter and damage have low contrast against the textured background; large sheets require full-area continuous inspection.
This station addresses the appearance and dimensions of yoga mats / exercise mats, focusing on stains, foreign matter, damage, print misalignment, color difference and length and width dimensions; the illumination is adjusted according to the sheet type.
Inspection takes place after cutting / after printing, with continuous or single-sheet imaging; defects against textured backgrounds rely on AI segmentation and dimensions use telecentric / contour measurement, adjusted according to the material.

What This Station Actually Has to Judge
| inspection item | Description |
|---|---|
| stain | Oil Stains, Discoloration |
| foreign matter | Adhered Particles |
| Damage / Hole | Holes, Tears |
| Print Misalignment | Pattern Offset |
| color difference | Uneven Color |
| dimension | Length/Width Out of Tolerance |
| Edge Evenness | Edge Evenness |
Why Inspect
Problems with manual visual inspection at this step
Yoga mats / exercise mats are foamed sheet materials; against textured and printed backgrounds, stains, foreign matter, and damage have low contrast, and manual visual inspection standards are hard to keep consistent.
Large sheet materials require full-width coverage; a single camera cannot capture it all, so stitching or continuous line scan with material movement is needed.
- Textured print backgrounds give low defect contrast
- Large-area sheets require full-width coverage
- Manual labour standards are hard to unify
- Print misregistration affects appearance
How Inspect
Stations and Inspection Chain
- 01 Continuous / single-sheet loading
- 02 Line-scan or zone imaging
- 03 Diffused light for stain and color difference inspection
- 04 Segmentation for foreign matter and damage
- 05 Print template matching

- 07 OK/NG output
- 08 Interlocking rejection/marking
- 09 Image and data archiving
How to Inspect
For foamed sheet, line scan or zone imaging covers the full width: diffuse light for stains and color difference, segmentation for foreign matter and damage, template matching for printing, and telecentric / contour measurement for dimensions; this is full-width texture imaging.

Submit sample testing
Typical OK/NG yoga mat / sports mat samples can be sent for measured testing: the full-width imaging and segmentation solution is determined by the material and pattern.

Can This Application Be Done? Sending a Sample for Testing Is the Most Direct Answer
Incoming material, part orientation and cycle time vary widely from factory to factory. Send us real samples and we will run imaging and judgement validation against your production line conditions, then give you a configuration proposal you can actually implement.
