Resumen
The invention describes a method for aligning the facets of a heliostat in a solar field, wherein a target heliostat (HO) is situated behind a reference heliostat (HR). The method comprises: orienting the target heliostat (HO) and the reference heliostat (HR) such that they face each other; obtaining an image by means of an image acquisition device (DAI) attached to a rear face of a reference facet (FR) of the reference heliostat (HR), said image containing at least the reference facet (FR) reflected in at least one target facet (FO); comparing features of the reference facet (FR) in the obtained image (I) with theoretical features corresponding to a correct alignment of the target facet (FO); and correcting the alignment of the target facet (FO) such that errors identified are eliminated. Also described is a heliostat designed for carrying out the method.
