摘要： To measure the position of a walking user's toe tip, a measurement device includes: a data acquisition unit that acquires, from a depth sensor capturing an image of a walking path and outputting image data having a depth of each pixel added thereto, image data in which no user is on the path as reference data and image data in which a user is walking on the path as walking data; a specific pixel extraction unit that identifies a depth-sensor side foot based on the walking data and reference data and extracts, based on the depth, a pixel corresponding to a toe-tip among the pixels of the specified foot; and a position calculation unit that calculates three-dimensional coordinates of the extracted pixel based on the coordinates in the image data and the depth of the pixel, and takes the three-dimensional coordinates as the position of the user's toe tip.

摘要： A gait analyzing device includes: a data acquisition unit acquiring first image data of a walking user and second image data of the walking user from a different direction, using a depth sensor; a skeletal information creation unit creating skeletal information identifying a position of a joint using depth information; a measurement information creation unit creating measurement information identifying a total number of steps and a ground contact history of left and right feet; a common part extraction unit comparing both instances of measurement information and extracts a part from the skeletal information in the first and second image data where the ground contact history is common; a correction processing unit correcting the skeletal information in the image data having the higher number of frames with the skeletal information in the image data having the lower number of frames; and an analysis processing unit analyzing the user's gait.

摘要： A part detection apparatus (10) including: a data acquisition unit (11) that acquires image data of a human to be subject, a contour extraction unit (12) that extracts an outline representing a contour of the human to be subject, from the acquired image data, and a part detection unit (13) that continuously calculates a curvature radius on the extracted outline and detecting a part of a body of the human to be subject based on a change in the calculated curvature radius.

摘要： An object management device 10 includes: a group setting unit 11 that, if a frame line surrounding objects on a screen is rendered, sets a group to which the one or more objects located inside of the frame line are to belong; a position detection unit 12 that detects positions of the one or more objects belonging to the set group, using the frame line as a reference; and a group moving unit 13 that, if movement is instructed for the group, moves the frame line and the one or more objects in a state in which the positional relationships therebetween are maintained, based on the detected positions of the one or more objects.
