I got it. Thanks again for your meticulous answer!
from coperception.
For your first question, I think @RoboticsYimingLi could probably give a more precise answer.
For your second question, as the variable name suggests, the labels are one-hot encoded, so the last two dimensions are one-hot labels for each voxel for each agent.
For example, label_one_hot[0][0][0]
could be
[[1, 0],
[1, 0],
[1, 0],
[1, 0],
[1, 0],
[1, 0]]
The first dimension 6 means there are 6 agents in the dataset, and the second dimension 2 means there are 2 categories, as specified in
coperception/coperception/configs/Config.py
Lines 172 to 173 in 7e99052
So, it means that the label for agent
0
at its voxelized birds-eye-view point cloud position [0, 0]
is 0

Thanks for your answer.
As for the first question, I will contact https://github.com/RoboticsYimingLi for more precise answer.
But for the second question, I am still confused. As I mentioned above, the shape of variable label_one_hot
is [6,256,256,6,2]
. If the foruth dimenstion means there are 6 agents in the dataset, what does the first dimenstion mean? You mean they are both standing for 6 agents in the dataset?
I found that for the fourth dimension of label_one_hot[0][0][0]
, the six elements are always the same.

The first dimension actually means the number of agents involved in the current training process. If you set rsu
to 0
to exclude RSU, then it will be 5
.
the six elements are always the same.
Yes, they should always be the same because the ground truth for a voxel should be the same for all agents.
