Abstract: 3D object detection based on visual information and LiDAR is one of the key technologies in intelligent driving perception and plays a crucial role in understanding complex driving scenarios. Due to the inherent limitations of single sensor and the complexity of multi-modal data, achieving high-quality 3D object detection is not a straightforward task. It requires considerring  many factors, including the heterogeneity of the data and optimization. Current research work mainly focuses on data fusion processing by leveraging the complementarity of single-modal data. To advance further research in 3D object detection, this paper first reviews 3D object detection methods based on visual information and LiDAR and then reviews 3D object detection methods based on LiDAR-Camera fusion from the perspectives of temporal fusion and stage-wise fusion. In addition, commonly used datasets and evaluation metrics are introduced, followed by performance comparisons of diffrent network architectures on these datasets. The advantages and limitations of different network types are analyzed accordingly. Finally, the challenges and solutions for the 3D object detection method based on visual information and LiDAR are given.
