The application provides a vectorization reverse construction method of an existing building indoor structure scene, and relates to the field of data processing. In the method, laser point cloud data and panoramic image sequences are synchronously acquired, and building structure semantics are extracted by image semantic segmentation. The image semantics are robustly migrated to the point cloud to form structure semantic point clouds. On the basis of eliminating non-building structure elements, a structure point cloud skeleton is constructed, and virtual placeholder point clouds are generated for open structures such as doorways and window openings. Then, continuous structure geometry is recovered by combining voxelization blocking completion and a three-dimensional convolution completion network. Finally, a three-dimensional structure grid model binding structure semantics is generated, and a two-dimensional structure vector drawing meeting engineering drawing rules is obtained by projection vectorization. The technical solution provided by the application facilitates improving the accuracy of the vectorization reverse construction of the existing building indoor structure scene.

This invention relates to the technical fields of intelligent diagnostic equipment for traditional Chinese medicine (TCM), medical IoT, and equipment and systems for internet-based TCM hospitals. Specifically, it relates to an integrated terminal and system for the four diagnostic methods (inspection, auscultation, inquiry, and palpation), incorporating a built-in TCM health model, wireless networking capabilities, and access to an internet-based TCM hospital platform for online registration, AI-based diagnosis, physician review, and electronic prescription processing. It aims to address the problems of single-function diagnostic equipment, data disconnect, and lack of a closed-loop diagnosis and treatment system. The terminal includes an integrated shell and integrated multimodal sign acquisition, edge computing core, interactive touch display, and secure communication gateway module. The acquisition module consists of inspection, auscultation, inquiry, and palpation units, synchronously acquiring tongue appearance, voice, chief complaint, and pulse wave features under a unified clock. The edge computing core incorporates a built-in TCM health model, deeply fusing multimodal features through a cross-modal attention mechanism.

This invention discloses a photothermal-triggered reusable drug delivery microneedle patch based on phase change materials, its preparation method, and its applications, relating to the field of pharmaceutical technology. The microneedle patch comprises several microneedles, each containing a drug-loaded matrix, a therapeutic drug, and photothermal nanoparticles. The drug-loaded matrix comprises a phase change material with reversible solidification-melting properties, capable of melting under photothermal triggering conditions and reverting to solidification after the photothermal triggering conditions disappear. The melting point of the phase change material is between 38°C and 45°C. The phase change material includes higher fatty acids and polyethylene glycol derivatives, and the photothermal nanoparticles include gold nanorods, graphene oxide, and polypyrrole nanoparticles. This invention proposes a microneedle patch using near-infrared light as a trigger signal and a phase change material with reversible solidification-melting properties. Through the melting process of the same phase change material under photothermal triggering, reusable drug delivery is achieved, overcoming the technical limitations of existing microneedles that only allow for "single-use, continuous drug release."
