This invention discloses an electromagnetic registration method, device, and medium for a bronchial navigation system, relating to the fields of medical navigation and electromagnetic positioning technology. The method first acquires CT image data of the target bronchus, constructs a three-dimensional image space, and completes airway image segmentation. Then, based on the airway image segmentation results, it extracts key points of the bronchus and the airway centerline in the image space, while simultaneously acquiring the corresponding key points and centerline point sets in the actual space using an electromagnetic positioning system. Subsequently, it uses the dual-space key points to complete coarse registration of the discrete point set, obtaining an initial rigid body transformation matrix. Finally, it uses this matrix to initialize the pose of the image centerline, and employs a point cloud iterative algorithm to complete fine registration of the centerline, outputting the final spatial transformation matrix. This invention employs a deep learning key point extraction and a two-stage coarse and fine registration strategy, significantly improving the robustness and accuracy of bronchial navigation registration, and adapting to precise navigation of equipment with complex airway structures.

This invention relates to the field of central air conditioning control system technology, specifically to an AI-based central air conditioning energy consumption optimization system. The system includes a multimodal data acquisition module, an edge fusion processing module, an AI prediction and decision-making module, and an execution feedback module. The multimodal data acquisition module collects environmental physical data, personnel activity data, and space usage status data in real time. The edge fusion processing module cleans, aligns, and extracts features from the collected multimodal data, outputting a regional-level predicted load feature vector. The AI ​​prediction and decision-making module runs an AI algorithm model based on the predicted load feature vector to generate predicted load data and an optimized control strategy set for the central air conditioning system. The execution feedback module converts the optimized control strategy set into control commands and sends them to the actuators of the central air conditioning system. This system has predictive capabilities, enabling precise control of central air conditioning in building zones and reducing central air conditioning energy consumption.
