关于Reszie3D

[betterhalfwzm]

您好，训练的时候用的dict(type='Resize3D', img_scale=(640, 384), keep_ratio=True),，测试的时候应该怎么用Reszie3D啊？

在 RandomCrop 之前加同样的 resize 即可。

请问您用的哪个config？看起来不像是repo里给定的。FCOS3D或者PGD在KITTI上的Resize3D如何使用还有待测试，如有需要可以先用DfM和Waymo上PGD的config尝试。

请问您用的哪个config？看起来不像是repo里给定的。FCOS3D或者PGD在KITTI上的Resize3D如何使用还有待测试，如有需要可以先用DfM和Waymo上PGD的config尝试。 @Tai-Wang pgd kitti那个config，换了个backbone，其他的应该一样 我尝试了训练原图，测试640384，3d位置不对； 训练图片640384，测试640384，3d位置不对； 训练图片640384，测试原图，3d位置不对； 只有原图训练原图测试3d位置才对的上

[betterhalfwzm]

当scale_factor=0.515时，是这个效果，训练图片640384，测试640384，kitti的原图是1242, 375，必须保持同比例缩放吗？

pgd 训练nus，@Tai-Wang train：

@betterhalfwzm 你好，关于Resize3D在测试的时候怎么用的问题您这边解决了么？
