Overview
The PPE Detector for Worker Safety - is a real-time image recognition and classification model for PPE monitoring in industrial settings. Trained on a synthetic dataset of 100,000 images, it analyzes live footage from high-resolution cameras to identify workers wearing protective gear. The solution detects the presence of seven object classes on a worker: Bare Head, Helmet, Ear Protection, Welding Mask, Bare Chest, High Visibility Vest, Person. The ML model can be used in manufacturing, construction, steel, oil & gas, and other industrial environments.
We also have a ready to use software, PPE Monitoring Platform: https://aws.amazon.com/marketplace/pp/B08BT5CV2FÂ
We provide free support during the trial period! After you've succeeded with the subscription, reach out at: support@vitechlab.comÂ
Highlights
- Trained on a synthetic dataset of 100,000 images and fine-tuned on the VITech Lab privately collected a dataset of real images from IP/CCTV cameras. The training dataset was considerably enlarged with augmented data. A synthetic dataset was collected with domain randomization to fit real images. The model was trained on images of 640x640 resolution and accepts images of any size that are resized internally.
- Uses a modified YOLOv2 object detection architecture to detect people and pieces of equipment they wear. The inference time is independent of the number of people detected in a single image. Inference latency is dependent on the hardware.

Amazon SageMaker model
An Amazon SageMaker model package is a pre-trained machine learning model ready to use without additional training. Use the model package to create a model on Amazon SageMaker for real-time inference or batch processing. Amazon SageMaker is a fully managed platform for building, training, and deploying machine learning models at scale.
Version release notes
Improved prediction accuracy by extending the dataset used for training the model.

Inputs
- Summary
Supported content types: image/jpeg
This model accepts images in the mime-type specified above.
The image must be at least 320x320. The model resizes the image to 640x640 before performing the inference. Better results are achieved with 16:9 image proportions.
Content type: text/json
For every image, the model returns a single JSON file with all the detections.
The model returns a JSON object, that includes an array with individual elements for each person detected. Each element is a list of numbers: [X0, Y0, X1, Y1, confidence, class]
- [X0, Y0, X1, Y1] is the bounding box around the detected object.
- confidence: the probability (in percents) that given bounding box contains an object.
- class: integer index for the class in a following order: ['Bare Head', 'Helmet', 'Welding Mask', 'Ear Protection', 'NO Visibility Vest', 'High Visibility Vest', 'Person']
Prediction method takes no additional parameters.
We recommend using this model for real-time inference for better utilization of the endpoint. Optionally, batch transform is also available.
