基于运动方向的视角无关行为识别方法
Viewpoint Independent Behavior Recognition Method Based on Motion Direction
摘要
Abstract
Aiming at the activities directions of human are arbitrary, this paper proposes the viewpoint independent behavior recognition method. A camera with fixed position is used to measure the motion direction based on the change of mass center coordinates in world space. According to the direction, video sequences can be selected taken by the camera which visual angle is orthogonal or parallel to the movement direction. A database on key features of motion activity sequences is taken orthogonally and parallel to the subject's movement is established for several human behaviors indoors. The method of parallel line bound with single camera is used to reconstruct 3D coordinate of key points by image coordinate and conversion factor. The method is tested on sequences of video data of human motions indoors, and experimental results validate the good performance of the proposed approach in viewpoint independent behavior recognition.关键词
