Solar Panels Frames Quality Assessment

摘要

Maintaining solar plant maximum energy production requires a regular inspection of solar panels. Images stitching technique of captured videos is usually used to form panoramic image view of the solar plant. Analyze of those images help supervisors to detect cracks, dust accumulation,. ... Often captured videos are done using moveable devices, such as vehicle robots and drones. Usually, motion and shaking of devices provoke some blur captured frames which affect drastically the stitching process. In this paper, we study, experiment, and compare a set of techniques allowing to detect and discard blurred frames. As result, the algorithm based on Fourier Transform allows an efficient (i.e. accuracy of about 98 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">%</sup> ) and rapid treatment which can be easily integrated into online stitching process.
