Abstract
The present invention provides a sun position tracking method based on a black sun effect of an image sensor, a computer program including commands for causing a computer system to perform the method, and a solar sensor using the method. The sun position tracking method includes processing a plurality of images captured using a plurality of image sensors installed to capture a plurality of images of the sun irrespective of the position of the sun to estimate the center point of the black sun and track the position of the sun.
Claims20
A sun position tracking method based on a black sun effect of an image sensor, comprising:
- capturing one or more images using one or more image sensors;
- and
- processing the one or more captured images using the black sun effect.
A computer program stored in a computer readable medium to track a position of the sun on the basis of a black sun effect of an image sensor, and including commands for instructing a computing system to capture one or more images using one or more image sensors and to process the captured images using the black sun effect.
A solar sensor using a sun position tracking method based on a black sun effect of an image sensor, comprising:
- a sensor unit for acquiring one or more images captured using one or more image sensors installed to acquire images of the sun;
- and
- a processor for processing the one or more images using the black sun effect to track a position of the sun.
A solar sensor comprising 6 image sensor cameras installed at positions of 6 vertexes of a virtual icosahedron such that 3 cameras capture a black sun with hemispherical coverage irrespective of a position of the sun using a minimum number of image sensor cameras, the 6 vertexes including one reference vertex and 5 vertexes neighboring the reference vertex.
