The invention discloses a method for quickly reconstructing a three-dimensional model with textures based on a neural shader, which comprises the following steps of: S1, surrounding an object to be reconstructed, shooting a group of images at different angles, and preprocessing the images to obtain a foreground image, a camera pose and an internal reference as training data, S2, establishing an initial triangular mesh, S3, establishing a three-dimensional model with textures, and S4, constructing a three-dimensional model with textures. The method comprises the following steps: establishing a differentiatable renderer which comprises a rasterization part and a neural shader part, dividing the vertex and texture of a model into two optimizers, obtaining a rendered image by the model through the differentiatable rasterization part and the differentiatable neural shader, calculating the loss with an original image, and performing back propagation. The rasterization time is obviously shorter ...

The invention provides a hydraulic puller, and relates to a hydraulic tool which can be operated in narrow space and used for disassembling a coupling which is a transmission component between a motor and a pump. The hydraulic puller mainly solves the problems that an existing method for disassembling the transmission component, namely the coupling, between the motor and the pump comprises the steps of heating the coupling through flames and making the coupling retreat through knocking of a copper rod, the coupling and a bearing expand with heat at the same time and fail to retreat smoothly, the coupling and the bearing are prone to damage in the knocking process, much labor and time are consumed, and potential safety hazards are caused to operation of the pump. The hydraulic puller comprises a puller back plate and a hydraulic cylinder connected to the puller back plate. The hydraulic puller is characterized in that an oil injection hole communicated with the hydraulic cylinder is formed ...
