Open3D-based parameters and bx/by interpretation

[Md-aliy7]

Hi,

I am trying your algorithm on some .ply formatted files from built-in data in Open3D.
As I just have the 3D object, I need to capture the rgb and depth images using Open3D methods, also I get the extrinsic and intrinsic from Open3D Camera class methods.
Are the parameters obtained this way valid to be used in your algorithm?
Also, what are bx & by parameters in

bx = depth_intrinsic[0,3]
by = depth_intrinsic[1,3]

?

Thanks
