在机器视觉中，刚体变换经常用于计算一个经过旋转和平移后的新坐标。比较常用的旋转矩阵的表示形式有欧拉角表示法和四元素表示法。本例子是两种方法的matlab实现，希望对大家有所帮助。-In machine vision, is often used to calculate a rigid transformation through new post-rotation and translation coordinates. Commonly used representation of a rotation matrix representation of the Euler angles and four-element representation. This example is the two methods matlab implementation, we want to help.
