Sources of measurement error in digital posture analysis
If you cannot name error sources, you will mythologise software precision.
At a glance
- Tag each surprising delta with a setup suspicion before clinical story.
- Maintain a living error wiki with photos from your studio.
- Re-benchmark after app updates that touch landmark models.
Capture-phase errors
Distance, height, rotation, zoom, and focus alter pixel geometry. Fix these before interpreting millidegree differences.
Landmark-phase errors
Even assisted placement inherits prior assumptions. Train on ambiguous cases weekly in five-minute drills.
How many credits does each analysis type use?
Fast, Standard, Advanced, and Dynamic analyses use different credit amounts—there’s a dedicated guide in this hub; Pricing also has plans and FAQs on monthly renewal.
