Abstract
To accurately obtain the shapes of a hoisting load and an object located near the hoisting load, and the height of the ground surface, and present an accurate warning display when the hoisting load approaches the object. A guide information display device is equipped with a data processing unit which: estimates the top surface of a hoisting load, the ground surface, and the top surface of the object, on the basis of a data point group obtained by a laser scanner; generates guide frames representing guide frames that surround the top surface of the hoisting load and the top surface of the object, and also generates height information and height information which represent the elevation of the hoisting load and the object; calculates the distance between the hoisting load and the object on the basis of the estimated top surfaces of the hoisting load and object; and outputs a warning display when the distance is equal to or less than a threshold. The guide information display device is also equipped with a data display unit for displaying guide information obtained by overlapping an image captured by a camera with the guide frames, the height information and the height information, an…
