Best Budget 3D Scanning Setup for Large Rotating Metal Object (~$1000, Outdoor, No Markers)?

Hi everyone,

I’m new to 3D scanning and need advice on a budget-friendly (~$1000) setup to scan a large conical metal object in an outdoor environment.

Object Details:

• Shape: Conical
• Size: ~3.2m diameter, ~3m height
• Material: Metal (shiny, reflective)
• Motion: Mounted horizontally on a shaft, can only rotate along its axis (hub to base)
• Restrictions: ❌ No markers allowed on the surface

My Key Constraints:

• Budget: ~$1000
• Accuracy: 0.5 cm is acceptable
• Outdoor Scanning Challenges: Sunlight, reflections, and no ability to modify the surface

What I Need Help With:

1. What’s the best budget 3D scanning setup for this scenario?
2. Would a 2D LiDAR (e.g., RPLiDAR S3) with manual rotation work?
3. How to handle shiny surfaces in an outdoor setting without using markers?
4. Any open-source software tools for merging scans and generating a 3D model?

I’d really appreciate recommendations on hardware, software, and workflow strategies to get a decent 3D model under these conditions. Thanks in advance! ?
