Helmet and number plate detection

. Motorcyclists failing to wear helmets is one of the main reasons why people die in these kinds of crashes. Traditional approaches to ensuring motorcycle riders wear helmets include traffic police manually monitoring intersections or using CCTV footage to detect riders who are not wearing helmets. These techniques, however, necessitate a great deal of human labor and involvement. This system suggests using CCTV footage to automatically recognize non-helmeted motorcyclists and obtain their license plate information. Initially, the system classifies items in motion as either motorbikes or non-motorcycles. The system determines whether or not classed motorcycle riders are wearing helmets. The device uses an OCR technique to obtain the license plate number if the biker is not wearing a helmet.

Helmet and number plate detection in videos.Firstly, it can identify objects like helmets and number plates within video frames, utilizing a method known as object detection.Once a helmet is spotted, the code goes a step further, determining whether it is worn or not, a process referred to as helmet classification.To provide visual clarity, it draws boxes around these recognized objects and clearly indicates whether a helmet is being worn or not.Importantly, it operates in real-time, processing video frames as they arrive, making it suitable for dynamic scenarios.User interaction is also supported, as the code displays the processed video and halts when the user presses the "Esc" key.Additionally, it adeptly manages computer resources during video processing, ensuring efficient execution.In sum, these features together empower the code to detect, classify, and present real-time results for helmet and number plate identification in videos.This research unfolds through a systematic process designed to develop a robust system for helmet and number plate detection.Commencing with a meticulous data collection phase, a diverse dataset is curated, encompassing annotated images that simulate real-world scenarios.Subsequent to data preprocessing, involving resizing, normalization, and augmentation, a suitable deep learning model for object detection is selected, with a focus on balancing computational efficiency and accuracy.
Transfer learning becomes pivotal as the chosen pre-trained model undergoes fine-tuning on the annotated dataset, tailoring its capabilities to the nuanced task at hand.The training phase involves the careful partitioning of the dataset, hyperparameter adjustments, and continuous validation to mitigate overfitting.Evaluation metrics, such as precision, recall, and F1 score, guide the model's refinement, supplemented by post-processing techniques to enhance the accuracy of detections.
Integral to the research is the seamless integration of the trained model into real-time systems, optimizing for efficiency and speed.Rigorous testing and validation follow, ensuring the model's adaptability to diverse environments and scenarios.The iterative nature of fine-tuning and documentation safeguards the reproducibility and scalability of the developed system, ultimately contributing to the advancement of intelligent transportation systems and road safety.
