Traditional methods for photovoltaic panel defect detection primarily rely on manual visual inspection or basic optical detection equipment, both of which have significant limitations. Manual inspection is inefficient, prone to subjective bias, and often fails to identify subtle or hidden defects.
Visible light imaging offers broad coverage and low cost, enabling extensive inspections. To address the current limitations of low precision and high image data requirements in defect detection algorithms based on visible light imaging, this paper proposes a novel visible light image defect detection algorithm for photovoltaic panels.
It effectively detects the status of photovoltaic panels through surveillance and simple camera systems, offering real-time feedback on whether defects are present. This ensures the stable operation and long-term reliability of the power generation system. Fig. 13. The labeled output images for target detection of different models. 5.6. Discussion
