Hi all,
I’m assessing the Creality Raptor for field pipeline integrity work. The goal is to detect and quantify shallow dents on carbon‑steel pipe. Attached is a typical case: a dent measured at 0.086 in (≈2.18 mm) depth.
I know similar workflows are done with other brands (e.g., Creaform Handyscan), and I’d like feedback from anyone who has used the Raptor Pro for comparable tasks.
What I’m looking to confirm:
-
Small‑feature capability
-
Minimum reliably detectable dent depth.
-
Expected depth uncertainty for dents in the 2–3 mm range.
-
-
Accuracy over area
-
Single‑shot accuracy and volumetric accuracy over a 300–600 mm span on cylindrical surfaces.
-
Repeatability between scans in field conditions.
-
Whether photogrammetry/scale bars are advisable to control scale.
-
-
Surface and environment
-
Performance on painted, rusty, or slightly reflective steel; is matting spray required?
-
Outdoor/daylight use, shading needs, and any IP limitations.
-
Marker/target usage and spacing best practices on long pipe sections.
-
Minimum criteria I need to hit:
-
Detect/report 2–3 mm dents with depth uncertainty ≤ ±0.2–0.3 mm.
-
Volumetric accuracy across 0.3–0.6 m < 0.3–0.5 mm.
-
Deliverables: deviation color map and a report relative to a best‑fit cylinder.
Any real‑world experiences, parameter tips, or caveats would be greatly appreciated. Thanks!
