# Camellia Golden Hands Dataset 🖐️
|
| 10 |
+
|
| 11 |
+
This dataset contains absolute rigid-body kinematics for dexterous robotic hands, collected purely via monocular iPhone TrueDepth (Zero-GPU, Extreme Cost-Efficiency).
|
| 12 |
+
|
| 13 |
+
## 🚀 Why this dataset?
|
| 14 |
+
Traditional RGB tracking suffers from "perspective distortion" (the rubber-hand effect). Camellia V11 engine mathematically locks the `ratio_matrix_factor` to anatomical constants and decouples the wrist to absolute `(0,0,0)`.
|
| 15 |
+
**Result:** 100% rigid-body JSON data that can be fed directly into metal dexterous hands without IK solvers crashing.
