摘要：
Methods and systems are disclosed for calibrating a crane for crane geometry. A Global Navigation Satellite System (GNSS) receiver antenna is disposed on a point along a boom assembly of the crane, the crane configured to pivot about a pivot point. A working arm of the crane is rotated about the pivot point to at least three different positions. Three locations are determined in a geo-referenced coordinate system of the at least three different positions. A location of the pivot point is determined based on the three locations.
