Deep Learning Frontiers in 3D Object Detection: A Comprehensive Review for Autonomous Driving

Abstract

Self-driving cars, or autonomous vehicles (AVs), represent a transformative technology with the potential to revolutionize transportation. This review delves into the critical role of 3D object detection in enhancing the safety and efficiency of AVs, emphasizing its significance within the broader context of autonomous driving systems. We provide a comprehensive analysis of methodologies, including deep learning architectures such as Convolutional Neural Networks (CNNs) and recurrent neural networks (RNNs), evaluating their strengths and limitations in the context of 3D object detection. The evolution of benchmark datasets, including KITTI, Waymo, and NuScenes, is discussed, highlighting their importance in advancing detection algorithms and facilitating comparative analyses across various approaches. Key performance evaluation metrics, including Average Precision (AP) and Intersection over Union (IoU), are emphasized as essential tools for assessing detection accuracy. Furthermore, we investigate the integration of computer vision and deep learning techniques in object recognition, showcasing their impact on improving the perceptual capabilities of AVs. The paper also addresses significant challenges in 3D object detection, such as occlusion, scale variation, and the need for real-time processing, while proposing future research directions to overcome these obstacles. This comprehensive survey aims to provide valuable insights for researchers and practitioners, guiding the development of robust 3D object detection systems that are crucial for the safe deployment of autonomous driving technologies.
