Diving and Water Sports Gear AI Visual Inspection Equipment

Diving and water sports gear AI visual inspection equipment: for dive suits, surf suits, neoprene and SBR/CR materials, it inspects damage, holes, poor lamination, seams and foaming defects, and outputs OK/NG.

Products Overview

The defect characteristics of neoprene and elastic materials are completely different from those of ordinary fabric

Quick answers

Diving and water sports gear AI visual inspection equipment is used for inspecting wetsuits, surf suits and neoprene materials. Industrial cameras and custom light sources identify defects such as damage, holes, poor lamination, seam anomalies and uneven foaming, output OK/NG and interlock with the production line.

Neoprene differs greatly from ordinary fabric: it has thickness, is elastic, often has a foamed texture on the surface, and is frequently Multi-Layer Lamination structure. These characteristics determine that its defect forms differ — some are surface defects, and some are interlayer defects.

Common problems with diving suits include damage to the rubber layer, pinholes, delamination of the lamination, and insufficient seam strength. Defects such as pinholes are almost invisible under conventional lighting, but immediately form a clear image under transmitted light or at a specific angle.

Inspection of these materials also faces a practical problem: Elastic materials have a different shape under tension than when relaxed, so the loading and fixturing method directly affects the consistency of inspection results.

  • Materials: neoprene (CR), SBR, stretch fabric
  • Structure: commonly single-layer or multi-layer lamination
  • Inspection focus: pinholes, damage, bond delamination, seams
  • Key challenge: shape changes of elastic materials under tension

Core Functions

What the Equipment Can Do and How Far It Can Go

Suited to Elastic Materials

Feeding and fixturing solutions for elastic materials such as neoprene reduce image differences caused by tension.

Pinhole Inspection

Transmitted or backlight imaging makes pinholes and tiny tears clearly visible with high efficiency.

Lamination and Delamination Inspection

For multi-layer composite materials, poor interlayer bonding and local delamination can be detected.

Seam Inspection

Check the seam position, width and continuity.

Foam Texture Compatibility

The algorithm distinguishes normal foam texture from real defects, reducing false calls.

Result Interlocking

NG parts are automatically rejected or marked, and images are retained for re-judgement.

Elastic materials deform under load, and the way they are fixed during inspection affects judgement consistency. We recommend determining the feeding and fixing tooling at the solution stage.

Relationship Between Imaging and Judgement

Neoprene inspection has two key points: first, "pinholes must be inspected with transmitted light", since they are almost invisible under reflected light; second, "the normal foam texture must not be judged as a defect", which requires the algorithm to be able to distinguish texture from defects, commonly solved by segmentation combined with morphological 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

Common Question

How are pinholes in neoprene detected?
Transmission or backlight imaging is usually used. Under transmitted light, pinholes appear as obvious bright spots with far higher contrast than in reflective imaging. The minimum hole diameter that can be detected reliably depends on the camera resolution and field of view, and must be confirmed by measurement against the actual material and hole diameter requirements.
Are inspection results still accurate after elastic material is stretched?
It does have an effect, so the loading and fixing method is critical. It is recommended to fix the material flat in a controlled way at the inspection station to reduce image variation caused by tension changes. This must be taken into account during the solution design stage.
Will Foam Texture Be Misjudged as a Defect?
This is the typical difficulty with this kind of material. The approach is to let the algorithm learn "the statistical features of the normal texture" and judge regions that deviate significantly from the normal distribution as anomalies, instead of using a fixed threshold. A sufficient quantity of conforming samples is needed for training.
Are wetsuits inspected as finished products or as sheet material?
Inspection at the sheet stage intercepts raw material problems earlier, while inspection at the finished product stage is closer to the delivery standard. The tooling and algorithms have different emphases, so you can choose according to your quality strategy.
Can the Equipment Handle Sheets of Different Thickness?
Your actual thickness range and variation need to be confirmed. Thickness differences affect depth of field and illumination conditions; within a reasonable range they can be accommodated by adjusting camera and light source positions, but beyond that range a dedicated design is required.
What Information Do You Need to Provide?
Recommended to provide: OK / NG samples of sheets and cut pieces, material thickness and number of layers, quantified defect criteria, production line cycle time and loading method, installation space and power supply conditions.
