PROBLEM TO BE SOLVED: To provide a walking measurement system capable of grasping accurately walking property of a subject.SOLUTION: A walking measurement system 100 comprises a laser range sensor 10 and an electronic controller 20. The laser range sensor 10 emits laser beam so as to scan along a horizontal direction, and acquires distance information related to a distance with leg parts of a subject on which the laser beam is reflected, based on a reflection state of the laser beam, over time. A data analysis part 24 of the electronic controller 20 detects an observation position of the leg parts of the subject based on the distance information, and specifies the position of the leg parts based on the observation position. The data analysis part 24 calculates the observation position when the position cannot be detected, by interpolation with a curve based on the observation position which was detected before becoming a state in which the position cannot be detected, and the observation position which is detected after the state in which the position cannot be detected, when the observation position cannot be temporary detected based on the distance information.SELECTED DRAWING: Figure 1 |
