Ground Truth is a term that refers to real-world data used to learn and test AI model outputs in the field of artificial intelligence data. Ground Truth data is necessary for a lot of AI applications such as autonomous driving and audio or voice recognition.

The GT file upload format only supports JSON.
Upload conditions: It must have the same folder structure and file name as the uploaded resource file, in the JSON file structure.

The task type set in the project (box, keypoint, etc.), class, and attribute names and values must be the same.
Even if the case and spacing are different, the upload fails.
Example of GT file upload failure (1)
Class name registered in the project: car /
The class name is written in JSON: Car
Failure case due to conditions not in the project (2)
The value of the attribute ‘weather’ under class A registered in the project: sunny, cloudy, rainy
The class name is written in JSON: Snow
