摘要
文中以对鹿体姿态的识别为例，针对鹿体姿态的特点，提出了一种新的可应用于大型四肢动物体姿态识别的方法。首先采用数学形态学的方法对图像进行了处理，获得了鹿体图像南准确轮廓，然后分别用四个椭圆对所获得的图像中鹿的颈部、去除颈部的躯干以及四肢进行拟合．最后利用线性代数的知识分别求出这四个用以表征鹿体姿态信息的椭圆的长短轴长度和方向。
Take recognition of deer＇s posture for example and aiming at the characteristics of deer＇s posture,a new discriminating method which can be used in big quadrupeds＇posture is proposed in this article. First, adopt morphology methods to process image so that accurate outline of deer＇s image can be obtained. Second, fitting deer＇s neck, trunk without neck and the four limbs of the body with four ellipses. Finally, linear algebra knowledge is adopted to solve length and direction of the four ellipses which used to token the message of deer＇s posture.
