Abstract

The present invention provides a guide display device capable of recognizing a feature in a work area while distinguishing whether the feature is a moving body or not. In a guide display device of a crane, 3D maps are created for continuous frames; an altitude value for each grid in a 3D map that is created at time closest to the current time is obtained as a first altitude value; altitude values for respective corresponding grids in a predetermined number of 3D maps other than the 3D map that is created at time closest to the current time are obtained, and the average of the altitude values is calculated as a second altitude value; and it is determined that the feature is a moving body when the difference between the first altitude value and the second altitude value exceeds a predetermined threshold.
