Abstract
A method for determining a level of solar radiation at a point of interest (POI). Multiple sky images are captured by a distributed network of digital cameras. Sun location parameters are determined. A three-dimensional (3D) sky model is generated based on the sky images. Generating the 3D sky model includes generating 3D object data based on the sky images to model one or more objects in a region of sky, and generating position data to model a position of the one or more objects in the region of sky. A level of solar radiation at the POI is determined based on the position data and 3D object data of the 3D sky model and the sun location parameters.
Claims28
A method for determining a level of solar radiation at a point of interest (POI), the method comprising:
- capturing multiple sky images by a distributed network of digital cameras comprising multiple pairs or sets of digital cameras capturing sky images of a region of the sky;
- determining sun location parameters;
- generating a three-dimensional (3D) sky model based on the sky images, wherein generating the 3D sky model comprises:
- generating 3D object data based on the sky images to model one or more objects in the region of sky by generating a separate 3D model for each of the one or more objects based on the sky images captured by each pair or set of digital cameras;
- and
- generating position data to model a position of the one or more objects in the region of sky;
- determining a level of solar radiation at the POI based on the position data and 3D object data of the 3D sky model and the sun location parameters.

A system comprising:
- a distributed network of digital cameras comprising multiple pairs or sets of digital cameras to capture multiple sky images of a region of the sky;
- and
- a processor to:
- receive multiple sky images from the distributed network of digital cameras;
- generate a three-dimensional (3D) sky model based on the sky images, wherein generating the 3D sky model comprises:
- generate 3D object data based on the sky images to model one or more objects in the region of sky by generating a separate 3D model for each of the one or more objects based on the sky images captured by each pair or set of digital cameras;
- and
- generate position data to model a position of the one or more objects in the region of sky;
- determine sun location parameters;
- determine a level of solar radiation at the POI based on the position data and 3D object data of the 3D sky model and the sun location parameters.
