PPE Compliance Check
YOLOv8n PPEHard hat + safety vest detection per person, with explicit present/absent/unclear labels
Upload a photo and this detects each person and checks whether a hard hat and safety vest are visible on them, using a dedicated PPE-detection model (the site's general object detector has no safety-vest class at all).
Compliance is only reported when the model explicitly detects the item present OR explicitly detects it absent — a person the model can't confidently read either way is labeled "unclear," never guessed. Per-person attribution uses a head/torso spatial heuristic, not real person tracking.
What this doesn't do: this is not a certified safety-compliance system. Per-person item attribution is a spatial heuristic (head/torso region overlap with each detected person), not real tracking — a crowded or overlapping-people photo can misattribute an item to the wrong person. "Unclear" means the model didn't confidently detect the item present or absent, not that compliance is confirmed either way.
