Emerging-Industry Materials AI Visual Inspection Equipment
Emerging-industry materials AI visual inspection equipment: for materials and structural parts in emerging industries such as the low-altitude economy, commercial aerospace, humanoid robots and hydrogen energy, we first run a sample trial to build a sample library and judgement baseline before moving on to inline inspection in mass production.
Products Overview
Set the standard first: sample trials and inline inspection for small-batch, high-mix materials in emerging industry chains
Emerging-industry materials AI visual inspection equipment targets the materials and structural parts of emerging industries such as the low-altitude economy, commercial aerospace, humanoid robots, and hydrogen energy. A sample trial is used first to establish a defect sample library and a judgement baseline before in-line mass production inspection is discussed; surface vision covers only the surface and contour, while internal defects require non-destructive testing.
Low-altitude economy, commercial space, humanoid robots / embodied intelligence, hydrogen energy and other emerging industries share a common feature: Small batches, many varieties, new materials, defect standards still being formed. Their inspection requirement is not "full inspection against an existing standard", but "the standard itself has to be established first".
Therefore, this type of inspection solution must start from "How Standards Are Set" as the starting point: in the early phase, use a sample trial to build a defect sample library and a judgement baseline, make clear what counts as NG and what the acceptance criteria are, and only then discuss inline mass-production inspection. Skipping the sample trial and going straight to mass production usually gets stuck on "what to judge and how to judge it".
The materials are mainly carbon fiber prepreg, aramid, fiberglass, foam and honeycomb sandwich, and also lightweight structural parts (metal parts use a different imaging setup). It must likewise be stated that: Internal defects require non-destructive testing; surface vision only covers the surface and contour. Only when the boundaries are made clear can such exploratory projects move forward.
- Positioning: addressing inspection requirements for materials and structural parts in emerging industry chains
- Starting point: run a sample trial to build a defect sample library and judgment baseline before discussing mass production
- Materials: mainly carbon fiber / aramid / fiberglass / foam cores, with separate imaging for metal parts
- Boundary: internal defects require non-destructive testing; surface vision covers only the surface and contour
Core Functions
What the Equipment Can Do and How Far It Can Go
Sample Trial First
Build the defect sample library and judgement baseline first, then discuss mass production.
Small Batch, Multi-Variety Adaptation
Recipe switching / quick-change tooling handles multiple variants.
Composite Material Surface Inspection
Surface defects on carbon fiber / aramid / fiberglass.
Sandwich and Honeycomb Material Inspection
Foam / sandwich surface and contour.
Dedicated Imaging for Metal Parts
The metal portions of lightweight structural parts use a separate optical solution.
Clear Boundaries
Internal defects are routed to non-destructive testing; coverage is not overstated.

inspection defect
| Defect Types | Typical Manifestations | Inspection Focus Points |
|---|---|---|
| Surface Crack | Surface microcracks on emerging structural components | Requires sufficient pixel equivalent; run direction is random |
| Fiber misalignment / direction deviation | Ply direction does not match the design | Depends on stable lighting and texture analysis |
| Porosity (Surface) | Visible surface pores | Distinguished from normal texture |
| Resin Starvation / Resin Rich | Abnormal local resin distribution | Manifests as differences in gloss and texture |
| Foreign Matter / Inclusion | Mixed-in fiber and release film fragments | Suits deep learning |
| Delamination / bubbles (visible on surface) | Interlayer separation in sandwich materials | Requires multiple angles or specific illumination |
| Internal defects (delamination / porosity) | Bulk material property defects | Requires ultrasonic / X-ray non-destructive testing |
| Dimension / contour anomaly | Structural part outline and hole diameter deviation | Locate first, then measure |

Relationship Between Imaging and Judgement
The key to inspection in emerging industries is not "how powerful the equipment is" but "establishing the standard first". Under small-batch, high-mix production, defect definitions and acceptance criteria are often absent, so samples must first be accumulated through sample trials and a baseline established before inline mass production inspection has any basis. Skip this step and even the best equipment is hard to put into practice.
Vision System
How Cameras, Lenses, Light Sources and Controllers Are Configured
industrial camera
Area scan or line scan is selected by material area and minimum defect size; advanced materials are often in small batches
- Area-scan camera: fixed-shot, single-piece, intermittent feeding
- Line Scan Camera: Continuous Feed, Wide Format
- Back-calculate the pixel size from the smallest resolvable defect
lens
Determines field of view, distortion and depth of field; use telecentric lenses for dimensional measurement
- Standard industrial lens: appearance inspection
- Low-distortion lens: edge judgement on large areas
- Telecentric lens: hole diameter, contour, dimensional measurement
Light Source and Illumination
Composite materials and metals have different optical properties and require separate lighting setups
- Diffused light: color difference, stains
- Low angle / stripe light: scratch, indentation
- Transmitted light: holes, short shots
- Coaxial / polarized light: suppressing reflections from composites and metal
Controllers and Industrial PCs
The platform for running algorithms, outputting results and interlocking with the production line
- Industrial Computer or Vision Controller
- Light source controller dimming synchronized with strobing
- 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, to establish a stable coordinate system
- Shape / grayscale matching: suited to fixed stations
- Region segmentation after alignment avoids false calls caused by drift
Blob and Morphological Analysis
Defects with obvious gray-scale / color differences, such as stains, holes and foreign matter
- Threshold segmentation → connected-component statistics
- Depends on stable illumination
Edge and Contour Measurement
Judgments for dimensions, contours, hole positions, and spacing
- Sub-pixel edge extraction
- Line / circle / arc fitting and calculation
Deep Learning (Classification / Detection / Segmentation)
Variable-shape defects with undefined standards rely on samples from the sample trial
- Requires OK / NG sample training (accumulated in sample trials)
- Supports pixel-level segmentation to output defect size and position
- Sample coverage sets the upper limit
Automatic Alarm and rejection
How inspection results act on the production line
Inspection results are not only shown on the screen. Workpieces judged NG must have their positions marked, be rejected or sorted by interlocking, and have their images and judgement results archived for review and traceability.
The alarm method is set according to site practice: audible/visual alarm, pop-up window, PLC set bit, or all three at once. Critical defects and general defects can use different handling strategies.
- 01 Defect judgement result generation
- 02 NG marking and alarm trigger
- 03 Image and data archiving
- 04 Production line interlocking rejection / sorting
data traceability
Records, Queries and Quality Closed Loop
Per-Piece Records
The judgement result, defect type, position, and timestamp of every part are stored in the database
- Search by time / batch / defect type
- NG image retention for re-judgement
Batch and Recipe
Different materials 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 and defect distribution
- Interface method is subject to site conditions

What Information Do You Need to Provide?
Submit sample testing
Emerging-industry materials have "undefined standards and scattered varieties", so a sample trial is essential first. Please provide material samples and a preliminary defect definition; we will use the sample trial to build a defect sample library and judgement baseline, and then evaluate the in-line solution for mass production.
