"Automated Functions" is the heart of our project, where our vehicle does five important things by itself:
The foundation of lane following lies in advanced image processing techniques. Our autonomous vehicle utilizes a Region of Interest (ROI) approach to precisely identify and track lane markings on the road. By focusing on the relevant portion of the image, the vehicle's algorithms analyze lane curvature, position, and changes, enabling the car to maintain a steady course within the lane.
The power of image processing truly shines in object detection, where we utilize a two-fold approach. Our autonomous car employs advanced image processing techniques coupled with the HAAR Cascade Classifier. This cascade classifier is a machine learning-based method specifically trained to recognize patterns, including objects such as obstacles. The system processes real-time visual data to swiftly identify and track these objects. This dual technique, combining image processing and the HAAR Cascade Classifier, ensures rapid and accurate decision-making, enabling the vehicle to expertly navigate through dynamic road environments.collision avoidance.
Our road sign detection function employs the HAAR Cascade Classifier, a machine learning-based approach. By training the system on a diverse dataset of road signs, the vehicle can swiftly detect and interpret different signs, extracting essential information. This capability ensures the vehicle's compliance with road regulations, enhancing road safety through accurate and timely responses.
Traffic signal detection leverages the vehicle's image processing capabilities to identify changes in signal color. The system processes visual data from the traffic light area, applying color filtering techniques to discern red, green, and yellow signals. This enables the vehicle to respond appropriately, demonstrating a cooperative and informed approach to traffic signals.
The prowess of image processing extends to lane end detection. By analyzing visual cues, the vehicle can identify when a lane is approaching its termination. The system then triggers a lane change maneuver, taking into account neighboring lanes and other vehicles. This process ensures smooth and confident lane transitions, exemplifying the car's adaptability to changing road conditions.
With the fusion of cutting-edge image processing techniques, machine learning algorithms, and hardware integration, our "Autonomous Vehicle" project attains a remarkable level of autonomy. These five automated functions represent the culmination of technology and innovation, redefining driving as we know it. The vehicle's ability to interpret its surroundings with precision and make informed decisions underscores its potential to transform road safety and reshape transportation paradigms.
