Self calibration for crane geometry |
| 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. |

1. A method for calibrating a crane for crane geometry, said method comprising:
disposing a Global Navigation Satellite System (GNSS) receiver antenna on a point along a boom assembly of said crane configured to pivot about a pivot point; rotating a working arm of said crane about said pivot point to at least three different positions; determining three locations in a geo-referenced coordinate system of said at least three different positions; and determining a location of said pivot point based on said three locations. |
