Hard Hat Detection

Hard Hat Detection

Algorithm Introduction
Algorithm Introduction
This AI vision-based algorithm is designed to detect and alert on the wearing of safety helmets by personnel in designated areas. It provides output of personnel location bounding boxes and helmet detection confidence scores, supporting multiple postures including walking and standing. Specifically optimized for high-risk environments such as construction sites, this solution helps project managers enforce safety regulations and reduce accident rates.


  • ● Lighting conditions: Minimum 50% bright pixel ratio in human body regions
  • ● Image requirements: Recommended resolution 1920×1080
  • ● Target size: Minimum 32×32 pixels, maximum 512×513 pixels

FAQ

  • Algorithm Accuracy
    All algorithms published on the website claim accuracies above 90 %. However, real-world performance drops can occur for the following reasons:
    (1) Poor imaging quality, such as
    • Strong light, backlight, nighttime, rain, snow, or fog degrading image quality
    • Low resolution, motion blur, lens contamination, compression artifacts, or sensor noise
    • Targets being partially or fully occluded (common in object detection, tracking, and pose estimation)
    (2) The website provides two broad classes of algorithms: general-purpose and long-tail (rare scenes, uncommon object categories, or insufficient training data). Long-tail algorithms typically exhibit weaker generalization.
    (3) Accuracy is not guaranteed in boundary or extreme scenarios.
  • Deployment & Inference
    We offer multiple deployment formats—Models, Applets and SDKs.
    Compatibility has been verified with more than ten domestic chip vendors, including Huawei Ascend, Iluvatar, and Denglin, ensuring full support for China-made CPUs, GPUs, and NPUs to meet high-grade IT innovation requirements.
    For each hardware configuration, we select and deploy a high-accuracy model whose parameter count is optimally matched to the available compute power.
  • How to Customize an Algorithm
    All algorithms showcased on the website come with ready-to-use models and corresponding application examples. If you need further optimization or customization, choose one of the following paths:
    (1) Standard Customization (highest accuracy, longer lead time)
    Requirements discussion → collect valid data (≥1 000 images or ≥100 video clips from your scenario) → custom algorithm development & deployment → acceptance testing
    (2) Rapid Implementation (Monolith:https://monolith.sensefoundry.cn/)
    Monolith provides an intuitive, web-based interface that requires no deep AI expertise. In as little as 30 minutes you can upload data, leverage smart annotation, train, and deploy a high-performance vision model end-to-end—dramatically shortening the algorithm production cycle.
