mindsponge.common.quaternion_to_tensor
- mindsponge.common.quaternion_to_tensor(quaternion, translation)[源代码]
将输入的四元数变为Tensor。
\[\begin{split}\begin{split} &quaternion = [(x_1, y_1, z_1, m_1)] \\ &translation = [(x_2, y_2, z_2)] \\ &result = [(x_1, y_1, z_1, m_1, x_2, y_2, z_2)] \\ \end{split}\end{split}\]- 参数:
quaternion (Tensor) - 输入的初始坐标,shape为 \((..., 4)\) 的Tensor。
translation (Tensor) - 坐标平移值,shape为 \((..., 3)\) 的Tensor。
- 返回:
Tensor,返回 quaternion 和 translation 的连接结果,shape为 \((..., 7)\) 。
- 支持平台:
Ascend
GPU
