@Tai-Wang Can you help me with this question?
It's because monocular 3D detectors are sensitive to the change of input images. When the input resolution is changed, at least we need to allow the network to see them during the training phase. Actually, our pre-release version can support this augmentation and we will release this feature together with some others new in about 1-2 months.

Thank you very much I will try this resize3D right away.

Yes, thanks for your suggestions. We may consider adding some comments to avoid such confusion.
Prerequisite
Task
I'm using the official example scripts/configs for the officially supported tasks/models/datasets.

Reproduces the problem - code sample
First, you should change the
test_pipeline
in the config to,then, you should change the code https://github.com/open-mmlab/mmdetection3d/blob/master/mmdet3d/models/dense_heads/fcos_mono3d_head.py#L641 to:
Then you can run the validation:
Finally, you get:
Reproduces the problem - command or script
With less resolution, the mAP should be lower. but should not be 0.
Reproduces the problem - error message
No error, Just the mAP is low,and I don't know why.
