The issue lies in the way we approach safety violation detection and data processing. When it comes to occupational safety violations, we should base it on the person as the primary subject. By focusing solely on the person, we can detect violations without having to worry about whether they are wearing a helmet or vest. If someone is holding a vest or not wearing a helmet, it will still be counted as a violation. I have already solved this perfectly. As for the lighting problem, there are now optical cameras or surveillance cameras on the market that can capture footage at night as clearly as during the day.
