Image to 3D point cloud?

DrBwts opened this issue · 2 comments

How are you converting your 2D camera images to 3D point clouds?

You don't go into any detail about this in your paper or provide a reference for the method. I was wondering if you could either elaborate or point me to the code that deals with this method?

Depths could be directly converted into point clouds with camera parameters. It is not a method we propose or introduced by others, but one basic truth in 3D vision.

There are some online blog that introduce this, such as this.

I checked out your link & I'm not convinced you can calculate depth like that as equation 1 is not unique.
