New soiling detection method based on drones, AI, image processing

Developed by scientists in China, the proposed approach uses mathematical morphologies for image processing, such as image enhancement, sharpening, filtering, and closing operations. It also uses image histogram equalization and edge detection, among other methods, to find the soiled spot. A research group from China has developed a novel dirt-detection system for PV plants that uses a series of image-processing techniques, as well as unmanned aerial vehicles (UAVs) with cameras flying above the plants and an improved artificial intelligence (AI) algorithm for path optimization. "Compared with ...
