1. A guide display device of a crane, comprising:
a data processing section configured to create a plurality of planes by using point group data including a lifting cargo acquired with a laser scanner from above the lifting cargo, create a three-dimensional map with the plurality of planes, and create the three-dimensional map at a predetermined time interval,
wherein the data processing section sets a reference position to the lifting cargo in the three-dimensional map, and
wherein the data processing section tracks the lifting cargo in the three-dimensional map by setting a current plane located within a predetermined distance from a past reference position as a surface of the lifting cargo.
