The calculation of ground truth in data_loaders.py

[BiaoBiaoLi]

Thanks your work, In https://github.com/chrischoy/FCGF/blob/master/lib/data_loaders.py
M = (self.velo2cam @ positions[0].T @ np.linalg.inv(positions[1].T)
@ np.linalg.inv(self.velo2cam)).T
Why does the M not be np.linalg.inv(positions[0]) @ positions[1] ?
Thanks!!!

Thanks
