PROBLEM TO BE SOLVED: To provide a calibration apparatus, a calibration program and a calibration method for a distance sensor that can calibrate positions and directions of a plurality of distance sensors arranged in a certain environment without being provided with an initial value.SOLUTION: A measurement apparatus 10 includes a computer 12, and a plurality of distance sensors 14 are connected to the computer 12. The computer 12 detects a person observation point in each sensor 14 based on an output from each sensor 14, calculates a human movement locus from a temporal change of the person observation points, and then makes the movement loci calculated based on the output from the respective sensors 14 coincide with each other among the sensors 14. The computer extracts two person observation points on the coincident movement locus in accordance with a predetermined rule, and calculates restrictions between the sensors 14 about a distance and a relative angle between the sensors 14 generating the movement locus for each group of sensors 14 whose movement loci are made coincident, by using the extracted person observation points. Then, positions and directions of all the sensors 14 are estimated by using the restrictions between the sensors 14, and the estimated positions are adjusted. |
