The application discloses a face plastic surgery effect prediction method and system based on three-dimensional reconstruction, and relates to the technical field of image recognition. The method comprises the following steps: obtaining face original three-dimensional point cloud data of a surgery receiver, surgery adjustment parameters and individual physical parameters; constructing initial coupling proportion field data; inputting the surgery adjustment parameters into a directional stress release model, combining skin line direction data to calculate asymmetric stress vector data, and performing spatial orientation correction on the initial coupling proportion field to obtain asymmetric deformation trend data, which is input into a time rebound prediction model to generate time evolution prediction data in combination with individual physical parameters and tissue elastic characteristics; limiting local volume increment in the prediction data according to a scar tendency weight, generating target postoperative deformation prediction data, and performing component decomposition to output multi-dimensional interpretable deformation decomposition results. The application realizes high-precision and interpretable prediction of the soft tissue dynamic deformation process of the surgery effect.

This invention relates to the field of feature extraction technology, specifically to an AI-based method and system for facial skin texture feature extraction. The method includes the following steps: using an image acquisition device, a face region is captured and grayscale spatial distribution data is obtained; grayscale differences and transition features of each pixel in multiple directions are analyzed; and the responses of each directional channel are fused to obtain the skin texture distribution result. In this invention, the input stage maintains a balanced foundation for the original data through brightness spatial consistency and pixel continuity constraints. During feature extraction, multi-directional grayscale change aggregation and transition trajectory analysis are employed to distinguish the texture direction and structural distribution characteristics of local areas. For areas with significant differences, the allocation of parameters for each channel is adjusted based on the dominant directional response. Reflection interference positions are handled through dynamic weight correction, ensuring that the output result possesses structural integrity and directional response coherence in real space, effectively improving the skin texture mapping capability in complex scenes.

FIELD: medicine.SUBSTANCE: invention relates to simulators for practicing skills of applying surgical sutures to the skin and techniques of tying surgical knots. The simulator includes a multi-layer cushion simulating human tissues, a simulation of vessels in the tissues, and has a rectangular shape with rounded edges measuring 20 by 15 cm and a height of 1.8 cm. The simulator is made of hypoallergenic polymers and contains four layers simulating human tissues - epidermis, dermis, subcutaneous fat, muscles. Vessels of various diameters, filled with a liquid imitating blood, run in the subcutaneous layer. A flap of PVC artificial leather having a skin texture, treated with liquid release wax IZHWAX SP, is placed on a platform with legs measuring 25 by 20 cm. A part in the form of a side 1.75 mm high, printed on a 3D printer, is placed on the flap. A nylon stretch mesh with a density of 110 g / m2 is stretched over the part. The stretch mesh is fixed to the platform with clamps. A part in the form of an outer side with 'ears' 17 mm high, printed on a 3D printer, is installed on the mesh. The entire structure is completely pressed against the base using clamps so that the nylon mesh remains stretched. Platinum silicone rubber of appropriate parameters is poured into a separate container. The components are mixed and coloured with a dye for epoxy resin, and after the last layer hardens, all the existing 3D-printed sides and other parts are separated. The excess stretch mesh is cut off.EFFECT: possibility of performing training of intramuscular injection, layer-by-layer dissection of the simulator layers with a scalpel down to the underlying layers and applying sutures in hard-to-reach places, in particular on the muscle layer, fascia, aponeurosis.1 cl, 1 dwg

The application discloses a full-automatic cartoon confectionery forming machine, aiming at solving the problems of production process interruption, low efficiency and high health risk caused by manual recovery of leftover dough in the production of existing cartoon confectionery. The whole continuous confectionery feeding belt reduces the lodging of confectionery, and the independent cylinder controlled skin cutter realizes accurate cutting and flexible adjustment. The confectionery / skin double conveying line cooperates with the lifting mold driven by the hollow rotating platform to complete the integration of cutting and transfer, and the spraying mechanism enhances the bonding effect. At the same time, the leftover dough automatic recovery mechanism uses the vertical lifting belt and the horizontal conveying belt to efficiently recover the leftover dough. The three-roller dough crushing device prevents clogging and outputs continuous dough belt. Then, the dough is pressed and formed by the dough pressing mechanism and directly returned to the skin line, forming a full closed-loop production. The whole process automation of leftover dough regeneration not only reduces production interruption and manual intervention, but also guarantees food hygiene and safety, and significantly improves the utilization rate of raw materials and the efficiency of continuous operation of the equipment.
