Document Type and Number:
WIPO Patent Application WO/2017/170440
Kind Code:
A1
Abstract:
This measurement device 10 is provided with: a data acquisition unit 11 that uses a depth sensor, which is disposed so as to photograph a walking path and a space thereabove for the purpose of measuring the position of the toe tip of a walking user and outputs image data having the depth of each pixel added thereto, to acquire, as reference data, image data for a state in which there is no user on the walking path, and, as walking data, image data for a state in which a user is walking on the walking path; a specific pixel extraction unit 12 for specifying a depth-sensor side foot from the difference between the walking data and the reference data and extracting, on the basis of depth, a pixel from the pixels of the specified foot that corresponds to a toe-tip part; and a position calculation unit 13 for calculating the three-dimensional coordinates of the extracted pixel on the basis of the coordinates on the image data and the depth of the pixel and taking the three dimensional coordinates to be the position of the toe tip of the user.
