Classification: CPC G  B | IPC B  G

Claim 0:
1. A method for optical assessment of a heliostat, comprising:
generating point cloud data representing the heliostat by measuring spatial parameters of the heliostat;
isolating the heliostat data in the point cloud data;
filtering the isolated heliostat data;
fitting the filtered heliostat data to a bounding box;
translating the heliostat data to a plane;
segmenting a plurality of facets of the heliostat;
fitting each of the segmented facets to a respective plane;
generating normal vectors characterizing each of the plurality of facets; and
calculating a canting angle associated with each respective facet of the plurality of facets; and
correcting one or more canting angles of one or more facets of the heliostat from which the canting angle associated with each respective facet of the plurality of facets was calculated by a processor.
