KAN-RCBEVDepth: A multi-modal fusion algorithm in object detection for autonomous driving
This work addresses the critical problem of accurate 3D object detection for autonomous driving systems, offering incremental enhancements in accuracy and efficiency.
The paper tackled 3D object detection in autonomous driving by introducing the KAN-RCBEVDepth method, which fuses multimodal sensor data and achieved improvements such as a 23% higher Mean Distance AP (0.389) and 28.3% lower Velocity Error (0.4244).
Accurate 3D object detection in autonomous driving is critical yet challenging due to occlusions, varying object sizes, and complex urban environments. This paper introduces the KAN-RCBEVDepth method, an innovative approach aimed at enhancing 3D object detection by fusing multimodal sensor data from cameras, LiDAR, and millimeter-wave radar. Our unique Bird's Eye View-based approach significantly improves detection accuracy and efficiency by seamlessly integrating diverse sensor inputs, refining spatial relationship understanding, and optimizing computational procedures. Experimental results show that the proposed method outperforms existing techniques across multiple detection metrics, achieving a higher Mean Distance AP (0.389, 23\% improvement), a better ND Score (0.485, 17.1\% improvement), and a faster Evaluation Time (71.28s, 8\% faster). Additionally, the KAN-RCBEVDepth method significantly reduces errors compared to BEVDepth, with lower Transformation Error (0.6044, 13.8\% improvement), Scale Error (0.2780, 2.6\% improvement), Orientation Error (0.5830, 7.6\% improvement), Velocity Error (0.4244, 28.3\% improvement), and Attribute Error (0.2129, 3.2\% improvement). These findings suggest that our method offers enhanced accuracy, reliability, and efficiency, making it well-suited for dynamic and demanding autonomous driving scenarios.
