Abstract
There is provided a construction machine that can detect a positional displacement of a detection unit, the machine including a body, a plurality of distance sensors, a position information acquisition unit, and a positional displacement detection unit. The distance sensors are disposed so that detection areas of the distance sensors partially overlap. When a predetermined target is placed in an overlapping detection area, the positional displacement detection unit compares position information of the target that is acquired from distance image data of one distance sensor by the position information acquisition unit to position information of the target that is acquired from distance image data of the other distance sensor by the position information acquisition unit to detect a positional displacement of at least one of the one distance sensor and the other distance sensor with respect to the body.
