- 摘要：
PROBLEM TO BE SOLVED: To reduce the time for measuring the positions of several measurement terminals and the error in measuring.
SOLUTION: A measuring device 1, which measures blood flow change in the head 25 on the basis of detection signals of several probes 13 which are in contact with or close to the head 25 and measures the position of probes 9 and 13, includes: targets which have several position marks arranged around the probes 9 and 13 with a predetermined positional relationship photographing parts 22 and 23 which photograph the targets from at least two different directions a three-dimensional coordinate measuring part which classifies the several position marks detected in a photographed image into groups corresponding to the probes using the predetermined positional relationship and measures the three-dimensional coordinates of the several position marks and a float offset correction part which corrects the degree of floating of the probes 9 and 13 from the surface of the head 25 by obtaining a virtual plane including the several position marks measured by the three-dimensional coordinate measuring part for each of the probes, assuming normal lines on the virtual planes and moving the positions P1 and P2 of the probes 9 and 13 in the direction of the normal lines.
