This invention relates to the field of intelligent brain disease diagnosis technology, specifically providing an auxiliary diagnostic method and system based on multimodal decoupled dynamic graph learning. The method includes: acquiring and preprocessing multimodal data (such as neuroimaging, genetic markers, etc.) of the subject; extracting common pathological information and modality-specific features through a shared encoder and modality-specific encoders respectively, and optimizing the separation process using a decoupling loss function; furthermore, fusing all modality embeddings using a multi-head self-attention mechanism with a masked matrix to generate initial node representations, where the mask is used to suppress modality self-attention; subsequently, performing hierarchical dynamic graph convolution based on the node representations: in each layer, dynamically updating the graph adjacency matrix by combining the current node representation with the original features, and iteratively optimizing the node representations through message passing; finally, inputting the optimized representations into a classifier to obtain disease prediction results. This invention improves the automation performance and reliability of diagnosis.

This application discloses an adaptive obstacle detection method and apparatus for adverse weather conditions, relating to the field of autonomous driving technology. The method acquires multi-source sensor data from an onboard vehicle, combines it with pre-calibrated sensor parameters to generate spatiotemporally aligned multi-source sensor data, extracts features to obtain feature maps for each modality, and projects all feature maps onto a bird's-eye view BEV space of the same resolution, using the LiDAR coordinate system as a reference, outputting a multi-modal BEV feature set. The feature set is concatenated along channels to form global state features, which are input into a pre-trained dual-branch adaptive decision network to obtain the output decision result, thereby generating the final image BEV features. Combining the multi-modal feature confidence weight matrix, the final image BEV features and the multi-modal BEV feature set are weighted to obtain globally fused BEV features, which are input into a 3D obstacle detection head for decoding and output detection results. This application can improve the robustness of multi-sensor fusion perception and obstacle detection accuracy under adverse weather conditions.
