1 is a view for explaining an obstacle walking inspection device according to an embodiment.

The obstacle walking test may indicate a test for measuring and evaluating walking speed, stride length, interpolation, foot height when crossing an obstacle, and distances immediately before and after an obstacle, in order to identify a dynamic fall factor of the elderly. For example, in the obstacle walking test, obstacles having a height of 0 cm, 2.5 cm, 5.2 cm, and 15.2 cm can be installed at 5 m points to diagnose walking behavior of the elderly. At this time, the height of 0cm is the height corresponding to the floor, the height of 2.5cm and 5.2cm is the height corresponding to the threshold of the threshold and the bathroom, and the height of 15.2cm can be the general height of the chin of the road. Through this obstacle walking test, it is possible to grasp the characteristics of the obstacle walking frequently experienced in daily life, and through this, a close correlation with the fall of the elderly can be confirmed.

In the obstacle walking test, the variables include the speed at which the subject approaches the obstacle bar, the speed at which the subject crosses the obstacle bar, the vertical distance between the subject's feet from the obstacle bar, and the distance between the subject's feet and the forefoot of the subject from the obstacle bar. It may include at least one of the distance between the heel of, the subject's bow and the subject's interpolation. Here, the bow coverage may be a length starting from the right foot to the heel when stepping off the next right foot. Also, the interpolation may be a vertical distance between an extension line of the center of the left foot and an extension line of the center of the right foot.

As the test subject ages, features such as a decrease in walking speed, inefficiencies in motion over obstacles, an increase in vertical distance, and a widening in bow coverage may be strongly exhibited. An apparatus and a method capable of effectively performing the obstacle gait inspection will be described in detail.

Referring to FIG. 1, according to an embodiment, the obstacle walking inspection apparatus may include a guide rail 110, a pillar rail 120, an obstacle bar 130, and a depth camera 140. The obstacle walking inspection device is a device for inspecting the obstacle walking of the elderly testee, and automatically controls the height and/or angle of the obstacle according to the progress of the obstacle walking test, thereby reducing the hassle that the inspector must manually control the obstacle. It can be effectively solved. For example, the obstacle may be implemented as an obstacle bar 130 in the form of a stick.

The guide rail 110 presents the walking path of the examinee. For the obstacle walking test, it is necessary for the testee to walk one or more times along the path where the obstacle bar 130 is installed, and the guide rail 110 may present a path to be walked for the test for the obstacle walk. The test subject may walk at a predetermined distance from the guide rail 110.

Further, the guide rail 110 may be provided with a depth camera that detects the gait of the examinee. For example, the guide rail 110 may include a plurality of depth cameras 140 arranged at predetermined intervals.

For example, the pillar rail 120 may gradually increase or decrease the height of the obstacle bar 130 according to the progress of the obstacle walking test. In the example of FIG. 1, one pillar rail 120 is disposed, but according to an embodiment, a plurality of pillar rails may be disposed at a predetermined interval on the guide rail 110.

The obstacle bar 130 obstructs the subject's gait until it hits the subject's body. In other words, the obstacle bar 130 may interfere with the subject's gait, but may interfere with the function of the subject when the subject hits the body. For example, the obstacle bar 130 may be an object to be crossed in order for the examinee to continue walking in the form of a long stick. The obstacle bar 130 may be implemented with, for example, plastic, wood, air tube, or the like. The obstacle bar 130 can be placed at any angle, and when the subject touches the obstacle bar 130, the obstacle bar 130 can be separated from the pillar rail 120 without injury to the testee.

As such, by automatically controlling the height and/or angle of the obstacle bar 130 according to the progress of the obstacle walking test, the subject through repeated measurement according to the change in the height and angle of the obstacle bar 130, rather than a single shot, It can provide convenience to the inspector.
