Title:
THREE-DIMENSIONAL SPACE COORDINATE MEASUREMENT DEVICE
Document Type and Number:
WIPO Patent Application WO/2016/017580
Kind Code:
A1
Abstract:
In order to accurately measure a three-dimensional location even when a measurement wave is obstructed by an obstacle, this three-dimensional coordinate measurement device 1 is provided with a transmission device 11 acting as a displacement body that transmits radio waves, and with a reception device 12 acting as a stationary body that receives said radio waves. The coordinates of the transmission device 11 are calculated, by means of propagation path distance difference, using a reception unit 31 having a plurality of reception unit pairs in the reception device 12, and when the reception device 12 has moved, a location for which coordinates have been ascertained is measured again on the basis of movement information, and the coordinates of the reception device 12 are corrected on the basis of the measured coordinate change.
