Abstract:
A shovel according to an embodiment of the present invention is provided with: a lower traveling body (1); an upper turning body (3) turnably mounted on the lower traveling body (1); an attachment attached to the upper turning body (3); a stereo camera (S4) attached to the attachment, the stereo camera (S4) measuring the shape of a ground surface to be measured; a boom angle sensor (S1) for measuring the orientation of the attachment; and a controller (30) for calculating distance information from the stereo camera (S4) to the ground surface to be measured using first stereo pair images from the stereo camera (S4). The controller (30) calculates the distance information by excluding the effect of changes in the orientation of the attachment, the effect derived on the basis of a detection value from the boom angle sensor (S1).
