Question about obtaining correctly scaled point clouds

[oumaima-coder-0410]

Hello, I ran inference on a sequence of images using the images and the camera's intrinsic parameters as input. The point cloud I obtained looks visually good, but when I computed the dimensions of a cube in the point cloud, they did not match the real cube I have.
The real cube measures 79mm × 79mm × 79mm, but from MapAnything I obtained dimensions of approximately 0.44 × 0.45 × 0.47. I am not sure about the units, and the size is almost half of the real cube.
Could you please advise how to obtain point clouds with the correct scale?
Thank you in advance for your help!

I am facing similar issues. I want to pass both intrinsic and extrinsic of the cameras and see if the pointclouds matches with little errors.
