Json Datadefinition
This repository contains data structure definitions for the RoboCT group at Deggendorf. It includes custom data structure schemas, example data files, and validation scripts.
- Example Files: Stored in the
examplefolder, these files demonstrate data structure usage. - Validation Scripts: Located in the
scriptsfolder, these scripts validatethd_jsondata structure definitions against their schemas.
THD JSON
This data structure use always a human-readable .json for storing header information.
Projection
This schema defines the properties for projection data in THD JSON format.
