Since FAST-LIO2 performs a spatial downsampling with resolution 0.3 for each received LiDAR scan, for a fair comparison, we also perform such spatial downsampling in Point-LIO before the data sorting and point-by-point update. WebFusion low-resolution hyperspectral images (LR-HSI) and high-resolution multispectral images (HR-MSI) are important methods for obtaining high-resolution hyperspectral images (HR-HSI). Some hyperspectral image fusion application areas have strong real-time requirements for image fusion, and a fast fusion method is urgently needed. This paper …
