摘要
指尖提取已成为基于视觉的裸手人机交互的关键技术,针对目前很多识别手势和指尖检测方法存在的对设备要求高、系统效率低、局限于单指检测、应用局限性高和对于弯曲手指存在误检等诸多问题,提出了一种改进型高精度曲率多指尖检测法。首先,通过对提取到的手势边缘序列点求曲率和像素值判断法排除手指凹槽。同时还提出了掌心测距法结合手掌外接圆法等有效地去除了握拳时和手指半弯时解决类指尖误判问题的方案。最后,整合优化算法流程,实验验证表明该改进的检测方法能较好地提高程序运行效率,检测精度与运行速度得到了明显的改善。
Abstract
Fingertip extraction has become the key technology of bare hand human-computer interaction based on vision. Aiming at solving the high requirements for equipment,low system efficiency, limited to signle finger detection,high application limitations and error detection of bending fingers, and many other problems of many hand gesture recognition methods and fingertip detection methods at present,this article proposes a modified high precision multiple fingertips detection method based on curvature.Firstly,it eliminates the finger grooves by the curvature of extracted edge gesture sequence points and pixel values judgment method.And it proposes the palm ranging method and the inscribed circle of palm method to effectively wipe out the class fingertips error judgement of fist and bending fingers at the same time. Finally, it optimizates algorithm flow chart.Experiments show that the improved detection method has improved the efficiency of program and obviously improved the detection precision.
