  • Patent number: 10989839
    Abstract: In one embodiment, a ground-based sky imaging and irradiance measurement and prediction computing device: obtains, from an omnidirectional ultra-panoramic camera located at a ground-based mounting location, an image having a view of an entire sky located above the camera and a horizon-to-horizon view of ground and ground-based objects surrounding the camera; calibrates a relationship between locations of pixels of the image and real-world three-dimensional coordinates based on intrinsic/extrinsic properties of the camera; identifies image pixels that contain clouds; georegisters, the clouds to real-world three-dimensional coordinates; and estimates, cloud attenuation levels. A solar irradiance map can then be generated based on the georegistration of the clouds, sun position, and estimated attenuation level of the clouds, where the solar irradiance map indicates an estimation of solar irradiance to reach an area of ground surrounding the camera.
