How to reduce voxel size

[TianhaoFu]

hi,

nice repo!

i wonder to know how to reduce the voxel size?

thanks!

Hello @TianhaoFu,

Could this be what you are looking for?

Have a look at the voxel_size in the config. (configs/vista/vista.py)

hi, when i reduce the voxel size in this config

i found the ret_bev feature map and ret_rv feature from the backbone output have different channel, which mean i could't set the neck in_features channels

can you helps me?

thanks!

To reduce the voxel size, you can simply modify the configuration, but it is necessary to modify the configuration (input_channel, bev/rv_size, etc) of the attention module in ohs.py because the change in voxel size will lead to the change in the shape of 3D feature map produced by the 3D backbone, which will further influence the shape and the channel number of collapsed BEV and RV feature map.
