The invention discloses a calibrating device and a compensating method for a multi-shaft machine. The calibrating device comprises a seat body, multiple laser sensors, a reflecting part, a datum point structure and a photosensitive element. Each laser sensor is provided with a laser-emitting end for shooting a laser beam. Multiple laser beams are arranged in parallel. The reflecting part comprises a reflecting surface keeping equal distance with each laser-emitting end. The laser beams are vertically projected on the reflecting surface. The datum point structure is provided with a datum point detected by the photosensitive element. The calibrating device is arranged on an end surface of the multi-shaft machine. The laser sensors are driven to emit the laser beams so that distances between the laser-emitting ends to the reflecting surface are measured. The distances which are first distances are recorded. The value of each laser sensor is returned to zero. Compensating control is carried out to the multi-shaft
