ES-SIG2 All Sky Camera is an instrument used to monitor cloud cover. It consists of a series of optical lenses, filters, photoelectric sensors, and visual processing equipment. An all-sky imager can clearly capture images of the sky under full sunlight without any obstruction. It uses deep learning-based cloud vision algorithms to analyze parameters such as cloud cover, cloud type, and cloud trajectory in the sky images. Applications include meteorological observation, environmental monitoring, climate research, weather forecasting, solar energy assessment and monitoring, photovoltaic power prediction, power plant design, agricultural and forestry ecological building design, and satellite verification.
