Textile, Nonwoven and Fabric Inline Defect Inspection
JIVISION offers project development and technical assessment for Textile, Nonwoven and Fabric Inline Defect Inspection. Scope: Warp/weft breaks, holes, stains, colored yarn, folds and weft skew.
Scope and project-specific requirements
Task / output
Warp/weft breaks, holes, stains, colored yarn, folds and weft skew
Critical decision conditions
Texture periodicity, stretch and lateral drift affect decisions; include roll changes and joins, and score stopped and running sections separately.
Candidate technical approach
These are candidate implementation paths. Establish a baseline on real samples, then select or combine methods for imaging, speed and deployment constraints. Model names do not imply measured project results.
Object detection and confidence gating
RT-DETR, RTMDet, YOLOX, PP-YOLOE or rotated-box detection → non-maximum suppression and confidence thresholds → task rules
Region segmentation and quantification
U-Net, DeepLabV3+, SegFormer or Mask2Former → connected components and morphology → region measurements
Normal-sample modeling and anomaly localization
PatchCore, PaDiM, EfficientAD, FastFlow or STFPM → anomaly maps → threshold calibration and region merging
Image acquisition and hardware interfaces
Sensor drivers → MIPI, USB, GigE, line-scan or event acquisition → DMA, buffers and triggers → formats and ISP
Inputs for assessment
Provide product variants, defect definitions and reference parts, acceptable and borderline samples, field of view, takt time, cameras/lighting and trigger/reject interfaces.
Deliverables and interface agreement
Result schema, algorithm or processing configuration, example outputs and evaluation records for: Warp/weft breaks, holes, stains, colored yarn, folds and weft skew. Software format and source-code scope are agreed in the contract.
Specify input formats, output fields, coordinates/units, error states, versions and invocation methods. Define review and failure handling. The statement of work determines the exact scope of source code, executables, model files or analysis reports.
Acceptance method and measures
Task-specific acceptance measures
False calls per 1,000 m; minimum defect; width coverage; length-mark error
Separate test data by product, batch and defect class. Report misses, false calls, minimum visible conditions and line cycle time; test physical rejection separately.
These are measures to agree and test, not achieved-performance claims. Freeze samples, reference truth, thresholds and hardware/software versions before acceptance; report subgroup results and failures, identifying under-sampled conditions as uncovered.
Implementation and procurement stages
Define scope
Agree targets, stations, inputs and responsibilities in a statement of work, separating required and excluded conditions.
Sample validation
Use representative samples to test critical risks, document feasibility/failures and scope the next-stage estimate.
Development and integration
Implement agreed functions and interfaces with configuration/change records; use offline replay before authorized device or site integration.
Acceptance and handover
Retest against individual measures and hand over contracted artifacts with known limits; manage maintenance, expansion and changeovers as subsequent work packages.
Scope limits and licensing
Image decisions cover visible features under agreed conditions; acceptable appearance does not establish material, strength, sealing or electrical conformity.
Candidate technologies are not license clearance. Check code, model weights, training data and dependency versions separately. Replace, license or exclude components unsuitable for the intended commercial delivery. Customer data is not used for public training by default.
Project FAQs
What does this service produce?
Warp/weft breaks, holes, stains, colored yarn, folds and weft skew. Deliverables: Result schema, algorithm or processing configuration, example outputs and evaluation records for: Warp/weft breaks, holes, stains, colored yarn, folds and weft skew. Software format and source-code scope are agreed in the contract.
What needs to be confirmed first?
Texture periodicity, stretch and lateral drift affect decisions; include roll changes and joins, and score stopped and running sections separately.
How is acceptance defined beyond a demonstration?
Task-specific measures: False calls per 1,000 m; minimum defect; width coverage; length-mark error. Separate test data by product, batch and defect class. Report misses, false calls, minimum visible conditions and line cycle time; test physical rejection separately.
How are cost and schedule assessed?
After reviewing samples for warp/weft breaks, holes, stains, colored yarn, folds and weft skew, equipment conditions and interfaces, scope validation, development, deployment and acceptance separately. Data coverage, site changes and delivery rights affect the estimate; no fixed performance or schedule is promised before assessment.
