About AI Image Training

AI models that understand images learn from examples carefully prepared by people. Image annotators help teach these systems to recognize objects, people, and visual conditions, making accurate and consistent labeling an important part of building modern computer vision technology.

• Work on image-based object detection data
• Use human judgment to create reliable training examples
• Contribute to the development of AI vision systems

The Role

OpenTrain AI is seeking an experienced data-labeling expert for a Personal Protective Equipment detection project. You will annotate images by creating accurate bounding boxes and assigning the correct class label to each relevant object.

This is an expert-level, fixed-price contractor project with a total payment of $2,000 USD. The project is worldwide and requires English.

• Role: Data Labeling Expert
• Project focus: Personal Protective Equipment detection
• Data type: Images
• Annotation type: Object detection and polygon labeling
• Labeling software: Roboflow
• Payment: $2,000 USD fixed price
• Experience level: Expert

What You'll Do

You will review PPE-related images and mark the relevant objects precisely. Each annotation must use the appropriate class and maintain consistent boundaries across the dataset.

• Create accurate bounding boxes around objects in each image
• Assign the correct class label to every identified object
• Label gloves, hardhats, overalls, people, and safety vests
• Distinguish compliant and non-compliant PPE classes, including NO-Gloves and NO-Hardhat
• Work in Roboflow
• Maintain high accuracy and consistency across all images

Annotation Classes

The project uses the following annotation classes for PPE detection:

• Gloves
• Hardhat
• NO-Gloves
• NO-Hardhat
• No-Vest-Overall
• Overall
• Person
• Safety Vest

Requirements

This project is intended for an experienced image annotation professional who can follow labeling instructions carefully and produce dependable object-detection data.

• Proven experience with image annotation tools such as CVAT, Label Studio, or Roboflow
• Ability to maintain high accuracy across all images
• Ability to apply labels consistently throughout the dataset
• Familiarity with AI datasets for object detection is a plus
• English language capability
• Expert-level experience

Why Work in AI Training

AI training and data annotation are the human side of building artificial intelligence. Contributors prepare and review examples that help AI systems interpret visual information, and many projects offer remote, flexible ways to participate in a fast-growing technology field.

• Work remotely from anywhere with an internet connection
• Build experience in a rapidly growing AI industry
• Help shape how computer vision models understand the world
