Researchers have developed PRI-Net, a novel lightweight framework designed to improve the 3D localization accuracy of unmanned aerial vehicles (UAVs). This framework addresses challenges such as sparse LiDAR data, imbalanced modality fusion, and inefficient feature transmission. PRI-Net incorporates a 3D point cloud splatting strategy for dense depth map generation, a residual attention fusion module to mitigate modal bias, and a multimodal information bottleneck to filter irrelevant features. Experimental results indicate that PRI-Net achieves high localization accuracy with a reduced feature dimensionality, enhancing the efficiency and robustness of UAV sensing. AI
