abstract = {Road Lane detection is a fundamental component of Advanced Driver Assistance Systems (ADAS), as it enables vehicles to maintain proper lane positioning and enhances road safety. However, reliable lane detection in real-world environments remains challenging due to varying lighting conditions, shadows, faded lane markings, curved roads, and weather disturbances. Traditional edge-based methods often fail under such complex scenarios.
This paper presents a smart road lane detection system using computer This paper presents a smart road lane detection system using computer vision techniques implemented in Python with OpenCV and NumPy. The proposed framework employs a multi-stage image processing pipeline that includes grayscale conversion, Gaussian smoothing, Canny edge detection, region of interest extraction, and perspective transformation to obtain a bird’s-eye view of the road. A sliding window search algorithm is then applied to identify lane pixels, followed by second-order polynomial curve fitting to model lane curvature accurately. The detected lane boundaries are projected back onto the original frame and highlighted with a green safe-driving region overlay.
