Area of Science:

  • Materials Science
  • Remote Sensing
  • Artificial Intelligence

Background:

  • Ice accumulation on critical infrastructure, such as wind turbine blades, significantly degrades performance and poses safety risks.
  • Effective monitoring of ice formation is crucial for preventing failures and ensuring operational integrity.

Purpose of the Study:

  • To investigate the efficacy of hyperspectral imaging (HSI) combined with machine learning (ML) for detecting and classifying surface ice.
  • To evaluate the generalizability of ML models across different surface coatings and ice types.
  • To assess the impact of spectral band selection on classification performance.

Main Methods:

  • Acquisition of hyperspectral reflectance data using a push-broom HSI system under controlled laboratory conditions.
  • Generation of glaze and rime ice using a thermoelectric cooling setup on coated and uncoated surfaces.
  • Training and evaluation of Support Vector Machine (SVM) and Random Forest (RF) classifiers on spectral data.

Main Results:

  • Both SVM and RF models demonstrated high classification accuracy for surface ice detection.
  • Model performance decreased on black-coated surfaces due to higher light absorbance.
  • Distinguishing between glaze and rime ice was achieved using a multiclass RF approach.
  • Model performance was sensitive to spectral band selection, with SVM optimal in reduced bands and RF in full spectral range.

Conclusions:

  • HSI coupled with ML offers a robust solution for real-time surface ice monitoring in safety-critical applications.
  • The choice of ML model and spectral range impacts ice classification accuracy, particularly on varied surfaces.
  • This approach provides valuable data for developing targeted ice mitigation strategies for infrastructure.
