Industrial automation systems and integration — 3D Shape Descriptors for Fidelity Metrics of Digital Twin Shapes

Apstrakt

This Technical Specification defines a descriptor-driven method to evaluate shape fidelity between a physical item and its digital twin (DTw) representation.

It specifies:
- Required terminology, data models, and computation steps for using 3D shape descriptors to quantify 3D shape similarity.
- Taxonomy of descriptor classes.
- Conformance requirements for metric calculation and reporting.

Out of scope: Predictive simulation results (CFD/FEM) and non-geometric fidelity scoring such as motion or performance.
