摘要
利用双目视觉的几何约束关系,依靠人体指示姿态来实现非接触、无约束的目标指示识别。本文根据人体指示行为的生理特征及双目摄像机的几何约束,推导满足目标共面假设时从图像特征点求解指示目标位置的公式,通过将图像平面上指尖和眼睛的指示线映射到目标平面上,从而得到相应的人体指示位置,实验结果表明这一方法的正确性。
This paper introduces a method of unconstrained and non-contact pointing gesture recognition based on geometry--restriction of binocular visior. It deduces the formula of translating image coordination of eyes and finger to 3D coordination of pointing object in case that objects locate on one plan. The position of the pointing targets could be estimated through mapping pointing line of fingertip and eyes on imge plane to target plane,and the experiments show that this method is correct.
