Client’s Needs:

A leading automation machinery manufacturing company in Canada required precise product defect annotation for a large dataset. They sought a solution that would involve bounding box annotation and opted for the Computer Vision Annotation Tool (CVAT) for the task. The client needed a managed service to ensure the accuracy and efficiency of the annotation process.

Main Challenges:

The primary challenge was aligning annotators to adhere strictly to the schedule, as the client required weekly updates on 50,000 annotated images every Friday. Meeting this deadline while maintaining quality was critical.

Product Defect Annotation for manufacturing

Our Data Annotation Approach:

In navigating the intricacies of our project, we employed a strategic approach characterized by precision, efficiency, and a commitment to exceeding client expectations. The following solutions formed the cornerstone of our success:

CVAT Project Setup:

We configured the CVAT platform according to the client’s specified labeling skeleton, ensuring a seamless and customized annotation environment.

Annotator Vetting:

We thoroughly tested and vetted annotators with prior experience in bounding box annotation to ensure their competence for this project.

Parallel Annotation Team:

We assembled a team of four annotators to work in parallel, allowing for efficient annotation of a large volume of images.

Efficient Test Task:

We completed the test task, consisting of four sets of test images, within 48 hours, receiving positive feedback from the client.

Annotation QA Specialist:

 To ensure high-quality annotations, we introduced a dedicated Annotation QA Specialist who rigorously checked each set of annotations before submission to the client.

Daily Reporting:

Recognizing the client’s need for timely updates, we implemented daily reporting on the project’s progress, providing transparency and accountability.

Strict Schedule Adherence:

We implemented a robust schedule management system to ensure annotators consistently met the weekly update deadline of 50,000 annotated images every Friday.
