ros中的坐标系,主要包括:map,odom,base_link(base_footprint) 以及如laser,camera等传感器的坐标系; 这些坐标系间的关系可以用下图表示: 这是一个有向图,图中涉及四个坐标系,分别为map,odom,base_link和laser。 箭头分别表示从父节点到子节点的变换,所以这里注意在写变换矩阵的时候,是先平移,后旋转,并且是按照...
机器人坐标系一般使用机器人模型中的根坐标系(base_link 或 base_footprint) 里程计定位:父级坐标系一般称之为 odom。 传感器定位:父级参考系一般称之为 map。 当二者结合使用时,map 和 odom 都是机器人模型根坐标系的父级,这是不符合坐标变换中"单继承"的原则的,所以,一般会将转换关系设置为: map -> do...
