Algorithm of space plane parameters based on cross ratio invariance 基于交比不变性的空间平面参数算法
If the space shift invariance is replaced by the time shift invariance, the high resolution frequency estimation can be obtained using a single vector sensor. 如果将空间的位移变成时间的延迟,单个矢量传感器可以实现高分辨率的频率估计。
An application example is enumerated that the space plane parameters are confirmed based on invariance of cross radio. 列举一个应用实例,利用交比的不变性确定空间平面参数。
Then, combining a flexible arm measuring machine and a standard ball with space round fitting algorithm, the presented model parameters are calibrated. Also, based on principle of cross ratio invariance, a fast calibration approach is presented. 4. 使用柔性臂测量机结合空间球拟合、空间圆拟合算法对检测系统测量模型参数进行标定,同时提出了一种基于空间几何交比不变性原理的检测系统测量模型参数快速求解方法。
Therefore we need to construct a unified shape space with topological invariance to overcome those shortcomings. 因而,针对这些缺陷,我们需要构建一个统一的、具有拓扑不变性的形状空间。
