<P>PROBLEM TO BE SOLVED: To provide a wearable measuring device which measures the relative position of a foot of a second leg relative to the position of a foot of a first leg from a sensor of a brace mounted on the first leg without attaching a sensor or the like to the second leg of a user. <P>SOLUTION: The wearable measuring device 10 includes a leg brace 12 mounted on the first leg, an angle sensor 21 for detecting the angle of each joint of the leg brace, a camera 42 fixed on the leg brace, and a controller 32 for calculating the relative position of the foot of the second leg relative to the foot position of the first leg. The camera 42 is mounted on the leg brace 12 in the place where the second leg is photographed. The controller 32 carries out a first operation for calculating the relative position of the foot of the first leg relative to the position of the camera based on the joint angle detected by the angle sensor, a second operation for calculating the relative position of the foot of the second leg relative to the position of the camera based on the image in which the second leg is photographed, and a third operation for calculating the relative position of the foot of the second leg relative to the foot position of the first leg based on the results of the first and second operations. <P>COPYRIGHT: (C)2011,JPO&INPIT |
