1. Abstract

The Autonomous Lane and Obstacle Detection System is an AI-based application designed to identify road lane markings and detect obstacles using computer vision and deep learning techniques. The system processes images or real-time video captured by a vehicle-mounted camera to recognize lane boundaries, vehicles, pedestrians, and other road obstacles. It uses image processing, object detection, and lane estimation algorithms to analyze road conditions and provide visual warnings. This project supports autonomous driving research, advanced driver assistance systems (ADAS), and intelligent transportation technologies.

2. Objectives

1. To detect road lane markings using computer vision.
2. To identify vehicles, pedestrians, and obstacles on the road.
3. To analyze lane boundaries and vehicle positioning.
4. To provide real-time lane and obstacle detection.
5. To generate alerts for potential lane departures and obstacles.
6. To improve automated road environment analysis.
7. To support autonomous driving and driver assistance research.

3. Existing System

Traditional driving systems depend on drivers manually observing lane markings, surrounding vehicles, and road obstacles. Basic driver assistance systems may use separate sensors or image processing techniques with limited capabilities under complex road conditions.

Disadvantages of the Existing System:

1. Requires continuous driver attention.
2. Lane markings may be difficult to identify in poor visibility.
3. Basic image processing methods may struggle with curved or faded lanes.
4. Manual obstacle identification can be affected by driver fatigue.
5. Some systems have limited real-time environmental analysis.
6. Advanced sensor-based systems can be expensive.

4. Proposed System

The proposed system combines computer vision and deep learning to detect road lanes and obstacles automatically. It analyzes camera footage to identify lane boundaries, detect surrounding objects, and estimate their positions relative to the vehicle. The system displays detected lanes, obstacle bounding boxes, and potential warning messages through a monitoring interface.

Key Features:

1. Real-time lane detection and visualization.
2. Road boundary and lane marking identification.
3. Vehicle and pedestrian detection.
4. Obstacle detection using AI models.
5. Lane departure warning indicators.
6. Visual alerts for detected obstacles.
7. Live camera and recorded video processing.
8. Dashboard for monitoring detection results.
9. Optional integration with autonomous vehicle simulation environments.

5. Implementation Procedure

1. Requirement Analysis: Identify the lane detection, obstacle recognition, and monitoring requirements.
2. Dataset Collection: Obtain road images and driving videos from suitable datasets such as TuSimple, CULane, or BDD100K.
3. Environment Setup: Install Python, OpenCV, and the required deep learning frameworks.
4. Video Input: Capture road footage using a vehicle-mounted camera or load recorded driving videos.
5. Image Preprocessing: Resize frames, reduce noise, and apply suitable image enhancement techniques.
6. Lane Detection: Use Canny Edge Detection, Hough Transform, or a deep learning lane detection model to identify lane boundaries.
7. Obstacle Detection: Apply a pretrained object detection model such as YOLO to identify vehicles, pedestrians, and other supported objects.
8. Lane Position Analysis: Estimate the vehicle's relative position within detected lane boundaries.
9. Obstacle Analysis: Identify obstacles within the driving path and estimate their relative positions. Reliable distance estimation requires additional calibration or suitable sensors.
10. Alert Generation: Display warnings when a potential lane departure or obstacle is detected.
11. Dashboard Development: Create an interface to display lane markings, detected objects, and warning indicators.
12. Testing and Deployment: Evaluate performance under different lighting conditions, road curves, weather conditions, and traffic scenarios.
