Questions on ScaleX and ScaleY

[hyf015]

Hi, thank you for sharing the code!
In the example of pickle file, I found two arguments "ScaleX" and "ScaleY". However, I cannot find any descriptions of these two arguments. Can you share some details about what are these two args? Thanks in advance!

Hi,

The two scaling factors will be applied to focal length (in horizontal and vertical directions) for back-projecting image pixels to 3d when performing cross-projections. As we downsampled training images from their original resolution to our standard input dimensions, such scaling factors modify the corresponding focal length making it correctly match the downsampled image.

Thanks.
