The present application relates to the technical field of computer vision, and relates to a 3D Gaussian sputtering stylization method, system, device and storage medium; wherein the 3D Gaussian sputtering stylization method comprises the following steps: obtaining a style image and a three-dimensional Gaussian scene to be stylized; performing non-negative matrix decomposition on the style image to extract an initial color basis matrix and an initial coefficient matrix of the style image; constructing a color orthogonal decoding model according to the initial color basis matrix and the initial coefficient matrix, and recalculating color parameters of each Gaussian primitive of the three-dimensional Gaussian scene; performing style transfer optimization on the Gaussian primitive, updating trainable parameters until an iteration termination condition is reached; and determining a stylized three-dimensional Gaussian scene according to updated geometric attribute parameters and color attribute parameters. The present application can solve the problems of color incoordination and dirty color during 3D Gaussian sputtering stylization.

The invention discloses a breathable flyknit vamp and a production method, and belongs to the technical field of flat knitting fabrics, the breathable flyknit vamp comprises a breathable surface, support strips and air guide vanes, a plurality of breathable holes distributed in an array are formed in the breathable surface, the plurality of support strips are distributed around the breathable holes, two ends of each support strip respectively point to two adjacent breathable holes, and the air guide vanes are arranged on the breathable surface. The supporting strips are of a structure sunken in the surface of the ventilation face, the multiple air guide pieces are distributed around the multiple ventilation holes, the middle sections of the air guide pieces protrude in the direction away from the ventilation face, the air guide pieces and the ventilation face surround to form an air inlet and an air outlet which are communicated, and air outlet is closer to the ventilation holes than the air inlet. The sectional area of the channel is unidirectionally reduced. According to the breathable flyknit vamp and the production method, the air guide pieces with the Venturi tube structures are formed through multi-needle bed integrated weaving and are communicated with the air holes in a directional mode, active ventilation is achieved through the foot arch in the walking process, and the breathable efficiency of the flyknit vamp is effectively improved.

This invention provides a single-motor two-speed hybrid system and vehicle, belonging to the field of new energy vehicles. It includes an engine, an input shaft, an intermediate shaft, a motor connected to the input shaft, a two-speed shift assembly, a power on / off assembly, and a drive axle. The power on / off assembly connects the engine and the input shaft. The engine and motor are located at opposite ends of the input shaft. The motor establishes a first transmission path with the drive axle through the input shaft, and a second transmission path through the input shaft and the intermediate shaft. When the power on / off assembly connects the engine and the input shaft, the engine establishes a third transmission path through the input shaft and the drive axle, and a fourth transmission path through the input shaft and the intermediate shaft. The two-speed shift assembly can simultaneously disconnect and periodically engage the first and second transmission paths, as well as the third and fourth transmission paths. This invention solves the problems of poor adaptability of existing single-motor single-speed hybrid systems and the complex structure of multi-speed hybrid systems.
