Abstract
Systems and methods for calibrating a heliostat () are disclosed. An imaging device () is positioned and oriented so that a calibration target () reflected by the heliostat () is visible at the imaging device and an image taken. Multiple features of the reflected calibration target in the image are identified and used to determine a centroid of reflection within the image which is then mapped to a corresponding centroid position on the calibration target. A vectorthat extends between the centroid position on the calibration target and a known position of the heliostat, as well as a vectors that extends between the known positions of the imaging device and of the heliostat, are determined. A normal vectorof the heliostat is determined as the vector that bisectsandand is used to calibrate the heliostat by updating parameters of a heliostat tracking model.
