Where did you get "self.worldcoord_from_worldgrid_mat" from? #4
Description
Thank you for your great work, it helps us a lot for our project. We really appreciate it.
We do not know how fixed parameters or matrices was designed? From the config of each dataset or manually setting?
For example, "self.worldcoord_from_worldgrid_mat = np.array([[0, 2.5, -300], [2.5, 0, -900], [0, 0, 1]])" in line 23 of "EarlyBird/EarlyBird/datasets/wildtrack_dataset.py". How to set self.worldcoord_from_worldgrid_mat like that.
And:
grid_y = pos % 480
grid_x = pos // 480
How to know the position divided by 480 but not other number.
