Night Vehicle Detection Flask App in Python Projects

Night Vehicle Detection Flask App in Python Projects
Abstract
The Night Vehicle Detection Flask App Project is a Python-based system designed to detect vehicles during nighttime using computer vision and deep learning techniques. The system focuses on overcoming challenges such as low-light conditions, headlight glare, and poor visibility. Using Convolutional Neural Networks (CNN) or YOLO (You Only Look Once) object detection models, the application identifies and tracks vehicles from video streams or uploaded images. Developed using Python and deployed with the Flask web framework, the system provides an interactive interface for uploading video footage or connecting to live camera feeds. Libraries such as OpenCV, TensorFlow/Keras, NumPy, and Pandas are used for preprocessing, model training, detection, and data handling. This project is applicable in traffic monitoring, smart city initiatives, and urban safety, offering real-time vehicle detection and monitoring during nighttime.
Existing System
Traditional vehicle detection systems primarily operate under daytime conditions and perform poorly in low-light environments. Methods like background subtraction, edge detection, or manual surveillance struggle with nighttime challenges, including shadows, glare from headlights, and poor contrast. Existing systems often fail to detect all vehicles accurately and cannot provide real-time tracking or counting. Additionally, many conventional methods lack user-friendly interfaces for quick deployment and visualization, limiting their applicability in smart city or traffic management projects.

Proposed System
The proposed Night Vehicle Detection Flask App uses deep learning and computer vision techniques to detect vehicles efficiently under low-light conditions. The video frames are first preprocessed using contrast enhancement, histogram equalization, and noise reduction to improve visibility. The enhanced frames are passed to a trained CNN or YOLO model to detect and track vehicles in real-time. Detected vehicles are counted, and duplicate detections are filtered to ensure accuracy. The system is implemented in Python, with OpenCV managing video processing, TensorFlow/Keras handling model training and inference, and Flask providing an interactive web interface for video upload, live feed monitoring, and visual output of detection results. By integrating low-light preprocessing, deep learning detection, and web deployment, the system delivers an accurate, automated, and real-time solution for nighttime vehicle monitoring, useful for traffic analytics, smart city applications, and road safety initiatives.
