Abstract
To accurately present information about the shape and location of a hoisting load and an object located near the hoisting load, regardless of the orientation and operational state of the crane. A guide information display device, wherein a camera images part of a work region of a crane, a laser scanner obtains a data point group of the work region captured by the camera, and a data processing unit: removes, from the obtained data point group, a data point group located between a hoisting load hanging from a crane and the tip end section of the telescopic boom of the crane; estimates, on the basis of the remaining data point group, the top surface of the hoisting load, the ground surface of the work region, and the top surfaces of objects located in the work region; generates guide frames which surround the top surfaces of the hoisting load and the objects; and overlaps the generated guide frames on the captured image, and displays the same on a data display unit.
