Based on the unit quaternion representation of orientations of the 6/6-SPS Stewart manipulator,an analytical expression that represents the orientation-singularity locus of the manipulator at a fixed position is derived and examples are given to illustrate the result.
基于单位四元数表示并联机构动平台的姿态,推导出当6/6-SPS型Stewart并联机构动平台处于固定位置时机构姿态奇异轨迹的解析表达式,并通过计算机仿真给出姿态奇异轨迹的三维可视化描述。
2.
The concept of quaternion and its operation rules were introduced first, then formulae for space resection based on unit quaternion were deduced.

3.
Firstly the unit quaternions are used to describe rotation matrix in the algorithm.
本算法采用单位四元数描述旋转矩阵,然后对严格的共线条件方程进行线性化,并按照带有约束条件的间接平差进行迭代解算。
补充资料:五佛生五菩萨五金刚五忿怒
【五佛生五菩萨五金刚五忿怒】
(杂语)五佛各出现菩萨,金刚,忿怒。此三者如其次第为法身,般若,解脱之三德,又为境智行之三轨。
