润色下面一段话：D-H法6869建模是对机器人的每一个关节都指定一个坐标系作为参考该关节的旋转或平移都用坐标系的旋转或平移来表示并用坐标系之间的齐次变换来表示两个关节之间的位姿关系。这种建模方法具有原理简单、模型直观的优点为机器人的运动学分析提供了强大的理论基础。

The D-H method [68][69] models each joint of a robot by specifying a coordinate system as a reference. The rotation or translation of the joint is represented by the rotation or translation of the coordinate system, and the pose relationship between two joints is represented by the homogeneous transformation between their coordinate systems. This modeling method has the advantages of simple principles and intuitive models, providing a powerful theoretical foundation for the kinematic analysis of robots.
