Abstract
Measure-up processes described herein provide data that enable three-dimensional (3D) positioning of a tip of a bucket of an excavator. The processes may include steps of curling a bucket of the excavator in and out, moving a stick of the excavator in and out, and moving the bucket so that it touches a point at different bucket angles. During each of the steps, data is generated using a tilt compensating survey pole and one or more inertial measurement units (IMUs).
