Astronomical Self-Calibration of Fisheye Cameras for Photovoltaic Sun-Tracking Applications
Vision-based photovoltaic (PV) tracking requires a calibrated mapping from fisheye pixels to physical solar directions, yet deployed cameras may lack calibration targets or a surveyed pose. This study asks whether timestamped sky images can recover a camera mapping that is internally consistent with a solar ephemeris,...
