Automatic Total Sky Imager

1.Automatic Total Sky Imager Product Overview

Automatic Total Sky Imager is a new generation ground-based automatic cloud cover observation instrument for cloud image acquisition, processing and quantitative analysis.The Automatic Total Sky Imager uses a high-precision fisheye lens to automatically record the cloud distribution in the sky without a sunshade and in direct sunlight, saving a picture of the cloud distribution in the sky. The protective glass uses a hard coated dome to protect the lens from weather and prevent the sun from damaging the CCD measuring element.

The equipment is easy to install and fully modular, the equipment can be equipped with ventilation and heating devices, and the imaging device will not be affected by weather changes. Analyze clear sky, hemispherical cloud cover, thick clouds and thin clouds, cloud cover by horizon and artificial horizon above cloud cover.

The cloud base height software provides the possibility to evaluate the cloud height and data (latitude, longitude and altitude) in real time on site and store them with each individual CMS image. This product has a dynamic analysis function, which can clearly record the cloud shape and cloud amount distribution in the sky during the day, and automatically save it to the local machine for comparison and analysis, or upload it to the cloud to identify cloud information through AI algorithms. It can be widely used in meteorology, civil aviation, transportation, marine research, smart cities and other fields.

The imager has a wide viewing angle of 175° and a high-resolution sensor, which can automatically record cloud information throughout the sky and convert it into quantitative cloud information through advanced cloud detection algorithms in the software. The imager can be connected to the Internet through a standard network card and transmit data to a server or monitoring computer through the network.

The imager control software integrates a horizon determination tool to provide users with flexibility and functional needs. For example, the software can be used to set the zenith angle range, ground object shielding area or user's area of interest to avoid the influence of inherent shielding around the station on the observation results. The imager also has good waterproof function.
