Abstract: Provided is a guide display device that prevents misidentification of the same feature as a plurality of different features or the ground surface even if an occlusion area occurs. A guide display device for a crane includes: a laser scanner that scans a suspended load and a ground surface from above the suspended load; and a data processing unit that calculates a representative point for each grid using the point cloud data acquired by the laser scanner, creates a three-dimensional map based on the representative points, and updates the three-dimensional map if the newly calculated representative point differs from the existing representative point. When an occlusion area, which is a shadow of the suspended load, occurs in the three-dimensional map, the occlusion area is not updated even if the newly calculated representative point and the existing representative point are different.
