Abstract
The present invention relates to a method for the mapping of a crane spreader and a crane load target, the method comprising the steps of: capturing scan data using one or more backreach range scanning sensors located on a backreach area of the crane; capturing scan data using one or more boom range scanning sensors located on the crane boom; and aligning and combining the backreach scan data and the boom scan data to generate a mapping of the crane spreader and the crane load target.

A method for the mapping of a crane spreader and a crane load target, the method comprising the steps of:
- capturing scan data of static reference structures using one or more backreach range scanning sensors located on a backreach area of the crane to determine the calibration parameters of the backreach range scanning sensors;
- capturing scan data of the crane spreader and the crane load target using the backreach range scanning sensors and translating same by the calibration parameters to obtain corrected backreach scan data;
- capturing scan data of reference features using one or more boom range scanning sensors located on the crane boom to determine calibration parameters of the boom range scanning sensors;
- capturing scan data of the crane spreader and the crane load target using the boom range scanning sensors and translating same by the calibration parameters to obtain corrected boom scan data;
- and
- aligning and combining the corrected backreach scan data and the corrected boom scan data to generate a mapping of the crane spreader and the crane load target.
A system for the mapping of a crane spreader and a crane load target, the system comprising:
- a crane comprising a crane boom and a crane spreader;
- one or more backreach range scanning sensors located on a backreach area of the crane;
- one or more boom range scanning sensors located on the crane boom;
- and
- a processing unit adapted to align and combine scan data from the backreach range scanning sensors and the boom range scanning sensors to generate a mapping of the crane spreader and the crane load target.
