Abstract

PURPOSE:To enable the accurate detection of the position of a moving body, by a method wherein laser sensors for reference provided in two laser projectors respectively are positioned on a line connecting two reference points on the occasion when the laser projectors are positioned at these reference points respectively. CONSTITUTION:Laser projectors 10 and 11 prepared by providing rotary laser projectors 15, 19 and laser sensors 16, 20 for reference on rotary main bodies 14, 18 are positioned at reference points A and B. On the main body 18 of the projector 11, a laser sensor 21 for positioning is so provided as to be shifted by 180 deg. from the sensor 20, and when a laser light of the projector 10 is sensed by the sensor 21, the main body 18 of the projector 11 is stopped so that the sensors 21 and 20 are positioned on a straight line Z connecting the reference points A ands B. Moreover, based on a timing from sensing of the light by the sensor 16 provided on the projector 10 to sensing of the light by the 21, the main body 14 of the projector 10 is rotated so that the sensor 16 to be positioned on the straight line Z. By this method, the sensors 16 and 20 can be positioned on the straight line Z connecting the reference points A and B when the projectors 10 and 11 are positioned at the reference points A and B, and thus the accurate detection of the position of a moving body is enabled.
