【摘要】 研究了基于视觉的静态手势识别技术,选取Hu不变矩作为手势识别的主要特征,采用了模板匹配法进行7种手势的识别,并与现有的虚拟雕刻技术结合,设计一个以手势变换来控制虚拟油泥的系统,满足用户从不同角度观看虚拟油泥的需求,以获得更加真实的感受。实验结果表明,在光照条件良好且背景单一的情况下,该方法具有很高识别率,并且有着很好的实用性。更多还原

【Abstract】 This paper researches on the statical hand recognition technology based on vision,selects Hu invariant moments as the main features of the gesture,uses the template matching method for the identification of gestures,and designs a system with existing virtual sculpting techniques to control virtual clay through transform the hand gesture. This system meets user demand for virtual clay viewed from different angles,and is used to obtain a more realistic feelings. The result of the experiment shows that this method has a high recognition rate under a good illumination and single background condition,and it has a very good practicality.更多还原
