1.机械轴的转动模拟，轴随着支点缓慢转动 2.自动更改照片大小比例-1. Mechanical axis of rotation simulation, the slow axis of rotation with the pivot 2. Automatically change the picture size ratio

使用高斯列主元消去法编程可以减少计算的繁琐程度，大大降低运算复杂度-Gaussian elimination pivot column can be programmed to reduce the red tape of the calculation, greatly reduce the computational complexity

kalman 滤波器跟踪一个旋转点算法 使用opencv和visual c-kalman-Filter tracking a pivot point algorithm
