Title:

GUIDE INFORMATION DISPLAY DEVICE, CRANE EQUIPPED WITH SAME, AND GUIDE INFORMATION DISPLAY METHOD

Document Type and Number:

WIPO Patent Application WO/2019/017460

Kind Code:

A1

Abstract:

The present invention accurately obtains the shapes of a hoisting load and an object located near the hoisting load, and the height of the ground surface, and presents an accurate warning display when the hoisting load approaches the object. A guide information display device 50 is equipped with a data processing unit 70 which: estimates the top surface of a hoisting load W, the ground surface F, and the top surface of the object C, on the basis of a data point group P obtained by a laser scanner 62; generates guide frames GD1 representing guide frames that surround the top surface of the hoisting load W and the top surface of the object C, and also generates height information GD2 and height information GD3 which represent the heights H of the hoisting load W and the object C; calculates the distance between the hoisting load W and the object C on the basis of the estimated top surfaces of the hoisting load W and object C; and outputs a warning display when the distance is equal to or less than a threshold. The guide information display device 50 is also equipped with a data display unit for displaying guide information GD obtained by overlapping the image M captured by the camera 61 with the guide frames GD1, the height information GD2 and the height information GD3, and the warning display which were generated by the data processing unit 70.
