Scale AI JSON

Scale AI is a popular outsourced labeling platform; their API returns object detection annotations in this JSON format.

Overview

Once you're ready to get serious about a computer vision project, you are probably going to need to outsource your labeling. One popular service for this is Scale.com. Unfortunately, the results they send back are not in a format that is ready to go into common machine learning models.

That's where Roboflow comes in. Simply drop in the JSON files you receive from Scale's human annotators and we'll convert them to whatever format you need for your model.

Format Description

Below, learn the structure of Scale AI JSON.
