Non-Touching Measurement Method on Yaw Angle Using a Stereo Camera

Abstract

This letter proposes a measuring algorithm of yaw angle using a stereo camera. The proposed method estimates the change of the yaw angle by aligning the point groups with respect to the result of the three-dimensional reconstruction of consecutive frames obtained from the stereo camera. The algorithm prevents the degradation of 3D point cloud correspondence. Experimental results of head posture angle show the effectiveness of the proposed method.
