“Enhancing Safety: A Computer Vision Approach to Helmet Detection”
This is the 4th Installment of the Series. To catch up, you can always check out here: Series Introductory Blog.
Workers not wearing helmets in workplaces or individuals neglecting to wear helmets in automobiles present significant safety concerns that can lead to severe injuries or fatalities. The primary concern of not wearing helmets in workplaces or automobiles is the increased risk of head injuries. Head injuries can range from minor concussions to severe Traumatic Brain Injuries (TBIs), which can result in long-term disabilities or even death. Many workplaces and jurisdictions have strict safety regulations. Failure to comply with these regulations can result in legal consequences to individual as well as employer. Overall, ensuring the widespread adoption of helmets in workplaces and automobiles is essential for preventing avoidable head injuries and promoting a culture of safety and compliance. It requires a combination of regulatory enforcement, education, awareness, and technological interventions to address the underlying concerns effectively.
What is Safety-Helmet Detection?
Safety helmet detection is a process where a computer vision system is used to detect whether a rider is wearing a helmet or not. This system can be installed at various checkpoints such as traffic signals, toll booths, and entry points to public places and construction workplaces.
How does Deep Learning help in Automatic Helmet Detection?
Deep learning is a subset of machine learning that uses artificial neural networks to learn from large amounts of data. In automatic helmet detection, deep learning models are trained using large datasets of helmet-wearing and non-helmet-wearing people. The neural networks learn to recognize the features that distinguish helmet-wearing one from non-helmet-wearing one . Once trained, the deep learning model can be used to automatically detect whether one is wearing a helmet or not.
What are risks of not wearing helmet?
- Head Injuries: The primary concern of not wearing helmets in workplaces or automobiles is the increased risk of head injuries. Head injuries can range from minor concussions to severe traumatic brain injuries (TBIs), which can result in long-term disabilities or even death.
- Legal Compliance: Many workplaces and jurisdictions have strict safety regulations requiring the use of helmets in specific environments, such as construction sites, industrial facilities, or while operating certain types of vehicles. Failure to comply with these regulations can result in legal consequences for both individuals and employers.
- Risk of Accidents: Not wearing helmets increases the risk of accidents and injuries, especially in high-risk environments such as construction sites, mining operations, or during motor vehicle accidents. Helmets provide crucial protection against falling objects, impacts, or collisions.
What are the Benefits of Automatic Helmet Detection?
Computer vision-based helmet detection systems can play a crucial role in enforcing helmet-wearing regulations in workplaces and monitoring compliance on roads. These systems can automatically detect individuals not wearing helmets and one with helmet.
Automatic helmet detection offers several benefits, including:
1. Enhanced Road Safety: The most significant benefit of automatic helmet detection is that it enhances road safety by ensuring that all riders wear helmets.
2. Reduced Human Error: Automatic helmet detection eliminates the need for manual monitoring, which can be prone to human error.
3. Time and Cost Savings: Automatic helmet detection is a cost-effective solution as it eliminates the need for manual monitoring, reducing the time and cost required to ensure that riders wear helmets.
Real-time Surveillance of Safety-Helmet wearing people :
Real-time surveillance of safety helmet-wearing people involves using video cameras equipped with computer vision technology to detect whether individuals in a monitored area are wearing safety helmets.
In our project we have implemented this using Yolov8m which calculates number of people wearing Safety-Helmet in real-time.
Click Here to watch video results of counting number of people in real-time.
As you can see above in my project we have simply plot the bounding boxes of Helmets without confidence score (else it will become clumsy, just to look clean) and displays the current count of Helmets in the video.
This tool can find applications in many domains. Just to give you one of those, Remember those Traffic Cameras? which you encounter on a daily basis, this Tool can be implemented in these city surveillance cameras to give an automated estimate of how well are the traffic rules being followed (if helmets are mandatory). So, now you’ve figured out how you’re being caught by the Police when you think no one has seen you violating the rules, haha. Thanks to YOLO! :)
So overall, Real-time safety helmet detection in settings like construction sites enhances workplace safety by ensuring compliance with safety regulations. It reduces the risk of head injuries, improves safety culture, and enables prompt intervention when safety protocols are breached. This technology fosters a safer work environment, minimizes accidents, and safeguards workers’ well-being, ultimately enhancing productivity and reducing liabilities.
FAQs
Q: How accurate is automatic helmet detection?
