Researchers have developed a new framework for classifying airborne multispectral point clouds, which combine 3D spatial and spectral information. The proposed method utilizes a two-stream feature fusion approach with attention mechanisms to enhance the representation of complex spatial-spectral data. It also incorporates a joint loss function to address challenges like unbalanced sample distribution and spectral similarity between classes. Experiments on two datasets show the framework outperforms existing state-of-the-art methods. AI
