Multi-sensor information fusion in Internet of Vehicles based on deep learning: A review

Environmental perception is a crucial component of intelligent driving technology, providing the informational foundation for intelligent decision-making and collaborative control. Due to the limitations of single sensors and the continuous advancements in deep learning and sensor technologies, multi-sensor information fusion in the Internet of Vehicles (IoV) has emerged as a major research hotspot. This approach is also a primary solution for achieving full self-driving. However, given the complexity of the technology, there are still many challenges in achieving accurate and reliable real-time multi-source information perception. Current discussions often focus on specific aspects of multi-sensor fusion in intelligent driving, while detailed discussions on sensor fusion in the context of the IoV are relatively scarce. To provide a comprehensive discussion and analysis of multi-sensor information fusion in IoV, this paper first provides a detailed introduction to its developmental background and the commonly involved sensors. Subsequently, a detailed analysis of the strategies, deep learning architectures, and methods for multi-sensor information fusion in the IoV is presented. Finally, the specific applications and key issues related to multi-sensor information fusion in IoV are discussed from multiple perspectives, along with an analysis of future development trends. This paper aims to serve as a valuable reference for advancing multi-sensor information fusion technology in IoV environments and supporting the realization of full self-driving.
