Beschreibung
Zusammenfassung:	At an end portion of a telescopic boom (16) of a crane (10), a stereo camera (30) is installed which measures a distance from the end portion to an object, and an image-processing controller (60) which obtains three-dimensional position information of the object based on a reference point provided beforehand on the crane (10) from measurement data to the object by the stereo camera (30) is provided, and three-dimensional position information of an object in a surrounding area centering on the crane (10) by the moving the telescopic boom (16) is obtained, wherein in a case where the reference point has not been imaged, a position of a target object a position of which from the reference point has been already obtained is taken as a new reference point and three-dimensional position information of the object in the surrounding area of the crane (10) is obtained.
