Abstract
A construction machine includes a boom, an operator cab, a distance sensor, a displacement detection unit, a storage unit, and a position information acquisition unit. The distance sensor has a predetermined field of view and acquires distance image data indicating a distance distribution of an environment around the operator cab. The storage unit stores initial position information of the boom. The displacement detection unit compares comparative position information of the boom, the comparative position information being acquired from the distance image data by the position information acquisition unit, with initial position information of the boom stored in the storage unit to detect a displacement of the distance sensor with respect to the operator cab when the boom is brought into an initial posture again after initial setting.
