To provide guide information accurately indicating a traffic line of a lifted load.SOLUTION: A guide information display device includes: a data acquisition part having a camera hung by a wire suspended from a boom for taking a video of a region including at least a lifted load and a ground surface from above the lifted load moved according to the movement of the boom, and a laser scanner for acquiring point group data from above the lifted load in the region; a data display part for displaying the video of the camera; and data processing part for generating guide information to be displayed overlapping with the video of the camera based on the point group data acquired by the laser scanner. The data processing part estimates a reference height of the ground surface based on the point group data acquired by the laser scanner, calculates an imaging range of the camera based on the reference height of the ground surface, and generates guide information indicating a traffic line of the lifted load based on the imaging range of the camera.SELECTED DRAWING: Figure 33

    【課題】吊荷の動線を正確に表したガイド情報を提供する。【解決手段】ガイド情報表示装置は、ブームから垂下されるワイヤによって吊り下げられ、ブームの動作に応じて移動される吊荷の上方から、吊荷と地表面と、を少なくとも含む領域の映像を撮影するカメラと、領域において、吊荷の上方から点群データを取得するレーザスキャナと、を備えたデータ取得部と、カメラの映像を表示するデータ表示部と、レーザスキャナで取得した点群データに基づいて、カメラの映像に重畳して表示するガイド情報を生成するデータ処理部と、を備え、データ処理部は、レーザスキャナで取得した点群データに基づいて地表面の基準高を推定するとともに、地表面の基準高に基づいてカメラの撮影範囲を算出し、カメラの撮影範囲に基づいて、吊荷の動線を表すガイド情報を生成する。【選択図】図33
