手指関節可動域計測デバイスにおけるRGB-Dカメラのヨー角ずれ補正機能の評価

抄録

We are developing a measurement device that calculates the range of motion of finger joints from 3D point cloud data acquired by an RGB-D camera. The objective of this study is to enable measurement of the MP joints even when there is a misalignment in the yaw angle of the camera relative to the hand. To this end, we developed a function that automatically identifies the location of the hand surface to be measured using Hand Keypoints and acquires the point cloud data. As a result, the required joint angle measurement accuracy of 2 degrees was able to be satisfied if the yaw angle of the camera relative to the fingers is within 20 degrees.
