基于连接关系与对称关系的人体姿态估计方法

Pose Estimation Based on Connection and Symmetry

针对出现在人体对称部位上的误判问题,提出了一种基于连接关系与对称关系的人体姿态估计方法。该方法利用相互连接的部位和对称部位之间的依赖关系对无标记的静态图片进行人体姿态估计。该方法在PS模型的基础上,采用了已有的部位连接关系评价方法,提出了以角度关系评价人体下肢结构对称程度的评价方法,并给出了以HSV颜色直方图与SIFT特征来评价上肢和下肢外观对称程度的方法,综合连接关系和对称关系对人体姿态进行估计。该方法较好地解决了对称部位被重复检测的问题和由于背景干扰而出现的四肢误判问题。实验结果表明,与同类方法比较该方法具有较高的姿态估计精确度。

Aiming at the missing detection problem in symmetric parts of the human body, the method for human pose estimation based on connection and symmetry was proposed. PS model and the existing evaluation method based on connection relationship were used in the method. Angle relationship was used to evaluate the symmetrical degree of the human body＇s lower limb. Appearance feature was utilized to evaluate the symmetrical degree of the lower and upper limb, and the connection and symmetry relationship were utilized to estimate human body pose. The experimental results show that the method has improved the accuracy of human pose estimation.
