Abstract
To accurately present guide information which expresses the shape and height of a hoisting load and an object located near the hoisting load. A guide information display device is equipped with: a data acquisition unit provided with a camera for capturing an image of a hoisting load region which includes at least a hoisting load and the ground surface below the hoisting load from above the hoisting load, and a laser scanner for obtaining a data point group in the hoisting load region; a data processing unit for estimating the top surface of the hoisting weight, the ground surface, and the top surfaces of objects, on the basis of the obtained data point group, and generating guide frames which surround the top surfaces of the hoisting weight and objects; and a data display unit which displays guide information obtained by overlapping the generated guide frames and the captured image with one another.
