Lane tracking is a critical component of self-driving cars, enabling them to navigate roads safely and efficiently. This article discusses the utilization of TensorFlow, a powerful deep learning framework, in the context of image processing for lane tracking, focusing on its application in localization and sensor fusion. Self-driving cars rely on a multitude of sensors to perceive their surroundings and make informed decisions. Among these, vision-based systems play a pivotal role, as they provide real-time information about the road environment. Deep learning techniques, particularly convolutional neural networks (CNNs), have proven to be highly effective in processing visual data. TensorFlow, a popular open-source machine learning library, has emerged as a robust tool for implementing such networks. This article explores how TensorFlow can be leveraged for lane tracking. It delves into the development of CNN models tailored to detect and track lane markings in images captured by onboard cameras. Furthermore, the integration of lane tracking into two key aspects of autonomous driving: localization and sensor fusion. Accurate lane tracking is crucial for vehicle localization, as it provides critical positional information. TensorFlow-based models can contribute to improved localization accuracy by continuously updating the vehicle's position relative to the detected lanes. Additionally, sensor fusion is essential for consolidating information from diverse sensors like LiDAR, radar, and cameras. TensorFlow facilitates the fusion of lane tracking data with information from other sensors, enhancing the car's ability to perceive its environment comprehensively and make safe driving decisions.
