What is a photovoltaic Index (PVI)?

Firstly, aiming to address the problems related to missed extractions and background misjudgments, a Photovoltaic Index (PVI) based on visible images in the three-band is constructed to serve as prior knowledge to differentiate between PV panels and non-PV panels.

How can we determine optical differences between different bands of PV panels?

In order to further determine the optical differences between different bands of PV panels, we randomly selected 100 images from the AIR-PV dataset [ 36] and statistically analyzed the pixel values of the PV panels and non-PV panels (such as roads, substations, and vegetation) in each band.

How to evaluate PV panel extraction ability of PVI?

In order to evaluate the PV panel extraction ability of PVI more objectively and clearly, first, we calculated the PVI of all the images in the PVP dataset. Then, we transformed the PVI images into binary images using the Otsu [ 50] method. The evaluation metrics show that the mean values of IoU and F1 are 57.64% and 68.49%.
