Segmentation of photovoltaic module cells in uncalibrated electroluminescence images [PDF]
Machine Vision and Applications, 2021 AbstractHigh resolution electroluminescence (EL) images captured in the infrared spectrum allow to visually and non-destructively inspect the quality of photovoltaic (PV) modules. Currently, however, such a visual inspection requires trained experts to discern different kinds of defects, which is time-consuming and expensive.
