| The present invention accurately presents 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 50 is equipped with: a data acquisition unit 60 provided with a camera 61 for capturing an image of a hoisting load region WA which includes at least a hoisting load W and the ground surface F below the hoisting load W from above the hoisting load W, and a laser scanner 62 for obtaining a data point group P in the hoisting load region WA; a data processing unit 70 for estimating the top surface of the hoisting weight W, the ground surface F, and the top surfaces of objects C, on the basis of the data point group P acquired by the laser scanner 62, and generating guide frames GD1 which surround the top surfaces of the hoisting weight W and objects C; and a data display unit 80 which displays guide information GD obtained by overlapping the guide frames GD1 generated by the data processing unit 70 and the image M captured by the camera 61 with one another. |
