[0002] With the development of natural sciences, the importance of sky observation in meteorological research, climate prediction, and environmental monitoring has become increasingly prominent. Early sky observation relied primarily on manual methods, with professionals observing and manually recording data. The accuracy of this traditional method heavily depended on the observer's experience and skill level, leading to poor data consistency. Furthermore, manual observation was inefficient, difficult to achieve continuous monitoring around the clock, and costly in terms of manpower. To overcome these shortcomings, all-sky imagers emerged and have gradually replaced traditional manual observation methods, significantly reducing manpower costs, improving observation accuracy, and enabling unattended continuous observation.

[0081] This utility model provides an all-sky imager that integrates a first night vision rangefinder camera, a second night vision rangefinder camera, a night vision recognition camera, a fisheye recognition camera, a first fisheye rangefinder camera, and a second fisheye rangefinder camera by setting up a main imager and a secondary imager. The first and second night vision rangefinder cameras are used to measure cloud height in nighttime mode, while the first and second fisheye rangefinder cameras are used to measure cloud height in daytime mode. The night vision recognition camera and the fisheye recognition camera are used to distinguish cloud types and calculate cloud coverage in nighttime and daytime modes, respectively. A first and second protective cover are used to cover and protect each camera, and a first and second wiper mechanism are respectively installed on the outside of the first and second protective covers. The wiping operation keeps the outer surfaces of the first and second protective covers clean, preventing image quality from being affected by environmental pollutants. Adapting to complex changes in various weather conditions, this invention solves the problem of not being able to achieve continuous and stable observation of the sky due to complex and changeable weather conditions, thus achieving continuous all-weather sky observation.
