Problems solved by technology

[0007] However, the conventional method of clipping an image by an observer has a problem that the burden on the observer is very large.
In addition, which image to cut depends on the experience and skills of the observer. Without a good observer, the subject cannot be guided, and the convenience is poor.
In addition, in the three-dimensional motion analysis device described in Patent Document 1, the subject wears a plurality of markers and takes pictures with a plurality of cameras, so the configuration of the device is complicated.

Embodiment approach

[0023] [Walk action display system]

[0024] First, use figure 1 as well as figure 2 The outline of the walking behavior display system according to this embodiment will be described.

[0025] figure 1 It is a figure which shows the concrete structure of the walking behavior display system 1 concerning this embodiment.

[0026] figure 2 It is a block diagram showing the functional configuration of the walking motion display system 1 according to the present embodiment.

[0027] Such as figure 1 As shown, the walking behavior display system 1 includes: a triaxial acceleration sensor 10 , an imaging unit 20 , and a walking behavior display device 30 . Such as figure 2 As shown, the walking behavior display device 30 includes a recording unit 31 , a storage unit 32 , a determination unit 33 , and a display unit 34 .

[0028] Hereinafter, each component of the walking motion display system will be described in detail using the drawings.

Embodiment

[0120] Here, use Figure 7 as well as Figure 8 An example in which an actual human being is used as the subject 2 and is measured and photographed wearing the triaxial acceleration sensor 10 will be described. In addition, in the examples, a person whose walking behavior is not appropriate is used as the test subject 2 . Therefore, on the report screen displayed on the display unit 34 , there is a difference between the operation represented by the schematic diagram and the operation represented by the representative image.

[0121] Figure 7 It is a diagram showing displacement data in the horizontal direction and vertical direction converted from acceleration data actually measured by the triaxial acceleration sensor 10 in the walking behavior display system 1 according to the present embodiment. In addition, in Figure 7 In , the horizontal axis represents the walking time, and the vertical axis represents the displacement in the horizontal or vertical direction.

Abstract

The walking motion display system (1) is provided with: a 3-axis acceleration sensor (10) that is attached to a subject (2) and measures acceleration data of the subject (2) while the subject (2) is walking; an imaging unit (20) that obtains video data showing the walking motion of the subject (2) by imaging the walking subject (2); a recording unit (31) that synchronizes and records the acceleration data and the video data; an identifying unit (33) that converts the acceleration data recorded by the recording unit (31) into horizontal displacement data and vertical displacement data and identifies an image corresponding to a representative motion during a walking cycle from the video data on the basis of the horizontal displacement data or the vertical displacement data; and a display unit (34) that also displays the image identified by the identifying unit (33) in the graphical view of the representative motion during the walking cycle.

Description

technical field [0001] The present invention relates to a gait behavior display system and a program for displaying an image showing a subject's gait behavior. Background technique [0002] Conventionally, in nursing care or rehabilitation training, the subject's gait motion was presented to the subject to guide correct gait motion. For example, a method is generally employed in which an observer cuts out a predetermined image and displays it while watching a video of the subject's walking behavior. [0003] In addition, Patent Document 1 discloses a three-dimensional motion analysis device that calculates the coordinate position of each marker from moving image data obtained by photographing a subject wearing a plurality of markers with a plurality of cameras, and calculates the coordinate position of each marker based on the calculated Coordinate position, analyze walking action. In the three-dimensional motion analysis device described in Patent Document 1, a posture ma...
