ARKit app allows us create an ARReferenceObject
, and using it, we can reliably recognize a position and orientation of real-world object. But also we can save the finished .arobject
file.
However, ARReferenceObject
contains only the spatial features information needed for ARKit to recognize the real-world object, and is not a displayable 3D reconstruction of that object.
func createReferenceObject(transform: simd_float4x4,
center: simd_float3,
extent: simd_float3,
completionHandler: (ARReferenceObject?, Error?) -> Void)
My question:
Is there a method that allows us to reconstruct digital 3D geometry (low-poly or high-poly) from .arobject
file using Poisson Surface Reconstruction
or Photogrammetry
?
You answered your own question with a quote from Apple's documentation:
An
ARReferenceObject
contains only the spatial feature information needed for ARKit to recognize the real-world object, and is not a displayable 3D reconstruction of that object.
If you run that sample code, you can see for yourself the visualizations it creates of the reference object during scanning and after a test recognition — it's just a sparse 3D point cloud. There's certainly no photogrammetry in what Apple's API provides you, and there'd not much to go on in terms of recovering realistic structure in a mesh.
That's not to say that such efforts are impossible — there have been some third parties demoing Here photogrammetry experiments based on top of ARKit. But
1. that's not using ARKit 2 object scanning, just the raw pixel buffer and feature points from ARFrame
.
2. the level of extrapolation in those demos would require non-trivial original R&D, as it's far beyond the kind of information ARKit itself supplies.
