Outdoor Apparel AI Visual Inspection Equipment
Outdoor apparel AI visual inspection equipment: for outdoor apparel such as shell jackets, ski wear, cycling wear and mountaineering jackets, it inspects laminated fabric delamination, uneven waterproof coating, seam tape defects, damage and holes and seam quality, and outputs OK/NG.
Products Overview
Special inspection requirements arising from three-layer laminated fabric and seam sealing processes
The outdoor apparel AI visual inspection equipment is used to inspect outdoor garments such as shell jackets, ski jackets and cycling jerseys. Using industrial cameras and dedicated lighting it identifies delamination of laminated fabric, uneven coating, seam-tape defects, damage and holes, and seam anomalies, outputs OK/NG and interlocks with the production line.
Outdoor apparel generally uses Multilayer laminated fabric: an abrasion-resistant outer layer, a waterproof breathable membrane in the middle and a skin-friendly inner layer. The layers are bonded by an adhesive layer, and delamination at any point makes the waterproof performance fail. Such defects are often invisible from the outside and require targeted illumination and imaging.
Besides the laminated structure, the seam tape is another key point. The width, continuity, and presence of bubbles or offset in the seam tape directly determine the waterproof rating of the finished garment, and these features do not have high contrast under conventional lighting.
Therefore, inspection solutions for outdoor apparel usually need to combine several illumination methods and to allow sufficient tolerance for "the normal texture of a good part"; otherwise the over-rejection rate stays high.
- Materials: three-layer laminated fabric, waterproof breathable membrane, seam tape
- Inspection focus: delamination, uneven coating, tape seam defects
- Optical strategy: combined illumination is required rather than a single light source
- Judgement strategy: separate critical structural defects from general appearance defects
Core Functions
What the Equipment Can Do and How Far It Can Go
Laminated Fabric Delamination Inspection
For multi-layer bonded structures, it detects interlayer separation and local blistering.
Coating Uniformity Check
Inspects waterproof coatings for missed areas, uneven thickness and pinholes.
Tape Seam Inspection
Inspect the width, continuity, bubbles and offset of the seam tape.
Damage and Holes
Transmitted-light imaging forms a clear image of damage and pinholes in the outer fabric.
Seam Quality
Check the seam position, width and stitch continuity.
Multi-light Source Switching
Switches illumination modes by inspection item, so one hardware set covers multiple defect types.

inspection defect
| Defect Types | Risk Level | Inspection Focus Points |
|---|---|---|
| Delamination / Blistering | Critical | Affects waterproof performance and is not easily noticed externally |
| Missing coating / pinholes | Critical | Requires dedicated illumination to form a clear image |
| Tape Seam Defects | Critical | Insufficient width, adhesive break, bubbles, offset |
| Damage / Hole | Critical | Transmitted-light imaging is the most direct |
| Seam Abnormality | Moderate | Sewing process quality issues |
| Stain / Color Difference | Slight | Appearance and acceptance related |
| Dimension / contour anomaly | Moderate | Affects subsequent assembly |

Relationship Between Imaging and Judgement
The core of laminated fabric inspection is "turning an invisible interlayer state into visible image features". Delamination and coating defects have almost no contrast under conventional lighting; illumination at specific angles, imaging in different wavebands or fusion of multiple images is needed to enhance the features.
Vision System
How Cameras, Lenses, Light Sources and Controllers Are Configured
industrial camera
Select area-scan or line-scan by field of view and minimum defect size; continuous web materials usually use line-scan cameras
- Area-scan camera: fixed-shot, single-piece and intermittent feed applications
- Line-scan camera: for continuous material travel, wide areas, and even-interval imaging
- Pixel equivalent is derived backwards from "minimum resolvable defect ÷ desired pixel count", rather than fixing the camera first
lens
Determines field of view, distortion, and depth of field; precision measurement requires telecentric lenses
- Standard industrial lens: low cost, suitable for appearance inspection
- Low-distortion lens: for large-format applications where the edges must also be judged
- Telecentric lens: suitable for hole diameter, contour and dimensional measurement
- Depth of field must match material waviness and fixture repeat positioning accuracy
Light Source and Illumination
Whether defects in flexible materials can be captured depends largely on the lighting
- Diffuse light: uniform illumination, suitable for color difference and stain applications
- Low-angle light: highlights scratches, indentations, wrinkles and other surface relief
- Backlight/transmitted light: highlights holes, damage and short shot
- Coaxial light / stripe light: suppresses reflection, suitable for coated or highly reflective surfaces
Controllers and Industrial PCs
The platform for running algorithms, outputting results and interlocking with the production line
- An industrial computer or vision controller runs the algorithms
- A light source controller handles brightness adjustment and strobe synchronization
- Interacts with the PLC to complete interlocking, alarming, and rejection
AI algorithm
Choose the Algorithm by Defect Form, Not by Complexity
Template Matching and Positioning
Locate first, then judge. Every defect judgment is built on a stable coordinate system.
- Shape matching / gray-scale matching: good stability, suitable for fixed stations
- Align first, then split the regions, to avoid false calls caused by position drift
Blob and Morphological Analysis
Suited to defects such as stains, holes and foreign matter that show a clear grayscale/color difference from the background
- Threshold segmentation → connected component statistics → judgement by area / aspect ratio / circularity
- High requirements on illumination stability; the light source must work with the fixture
Edge and Contour Measurement
Suitable for dimension, contour, hole position and spacing judgements
- Sub-pixel edge extraction to obtain a contour point set
- Fit lines/circles/arcs and calculate length, diameter, angle and position tolerance
Deep Learning (Classification / Detection / Segmentation)
Suited to defects such as scratches, wrinkles and skipped stitches, whose shapes vary and are hard to describe with rules
- When defect forms are irregular, it is difficult for rule-based algorithms to enumerate them all
- Requires OK / NG sample training; sample quantity and coverage determine the upper limit
- Enables pixel-level segmentation and outputs defect length, width, area and position
Automatic Alarm and rejection
How inspection results act on the production line
Inspection results are not only shown on a screen. Workpieces judged NG need to be Mark the position and interlock rejection or sorting, and archives the image and judgement result for that part for later traceability and re-judgement.
The alarm method is set according to site practice: audible and visual alarm, on-screen pop-up, PLC set bit, or all three at once. Critical defects and general defects can use different handling strategies — the former stops the machine and alarms, the latter is only marked.
- 01 image acquisition
- 02 Positioning and region segmentation
- 03 Defect Judgement
- 04 Combine results into a single OK / NG per piece
- 05 Result sent to PLC
- 06 NG Rejection / Sorting
- 07 Image and data archiving
data traceability
Records, Queries and Quality Closed Loop
Per-Piece Records
The judgment result, defect type, defect position and timestamp of every part are written to the database
- Supports retrieval by time, batch and defect type
- NG image retention for re-judgement
Batch and Recipe
Different products use different recipes, called up at changeover to reduce manual parameter tuning
- Recipes store the inspection region, thresholds and algorithm parameters
Production Line Data Integration
Exchange inspection data with the MES / host system
- Output pass rate, defect distribution and other statistics
- The interface method depends on the site system
