This invention relates to the fields of computer vision and computer graphics, and provides a method and system for dynamic human body reconstruction from monocular video based on 3D Gaussian splashing. The method includes the following steps: data preprocessing; initialization of the normalized space 3D Gaussian; deformation of the normalized space 3D Gaussian to an intermediate pose space to obtain a non-rigidly deformable 3D Gaussian and pose-related features; transformation of the non-rigidly deformable 3D Gaussian to the observation space using linear blending skinning to obtain the observation space 3D Gaussian; decoding the viewpoint-related color based on Gaussian color features, pose-related features, and viewpoint direction; constructing a total loss function including a normal consistency regularization term to optimize the 3D Gaussian attributes and network parameters; and rendering the target human body image using a differentiable Gaussian splash rasterizer. This invention enables rapid and fully automatic reconstruction from monocular video to a high-fidelity, animable human body model, applicable to fields such as virtual reality and film production.

The application belongs to the field of three-dimensional vision and digitization, and relates to a three-dimensional human body reconstruction method and system based on three-dimensional Gaussian splashing. The method steps are as follows: based on a layered hash coding parameter field, the center position of each Gaussian primitive in the constructed three-dimensional Gaussian primitive set is corrected, and the color of the Gaussian primitive under the current observation angle is predicted; based on the human body posture parameters and shape parameters corresponding to the monocular video sequence, linear mixed skin transformation is performed on the corrected Gaussian primitive to map to the posture space; based on the Gaussian primitive parameters mapped to the posture space, three-dimensional Gaussian differentiable rendering is performed on the Gaussian primitive mapped to the posture space to obtain a rendering image consistent with the corresponding view angle of the monocular video; based on the constructed joint loss function, the Gaussian primitive parameters and the layered hash coding parameter field are optimized to obtain a three-dimensional human body model. The application can quickly reconstruct an animatable three-dimensional human body model with stable contours and clear textures from a monocular video.

The application discloses a multi-view human body reconstruction method based on photometric consistency matching and optimization algorithm, which comprises the following steps: firstly, obtaining a rough human body surface through a visual hull algorithm according to a human body mask image; secondly, using photometric consistency constraint to optimize the shape initialized from the visual hull, so as to obtain a dense human body surface model; thirdly, calculating an illumination coefficient by using the diffuse reflection principle; and finally, using a light and shade optimization algorithm to perform high-speed real-time rendering on the dense human body surface model, so as to obtain a final simulation human body model.

Embodiments of the present application provide a rendering processing method and an electronic device, and relate to the technical field of terminals. The method comprises: determining a first human body model corresponding to each of at least one image frame in a first video. According to inertial measurement unit (IMU) data of a terminal device when the image frame is collected, a rotation matrix corresponding to the image frame is obtained, the rotation matrix being used to indicate rotation of a ground reference coordinate system relative to a device coordinate system of the terminal device. According to the rotation matrix, a first coordinate axis corresponding to a gravity direction in an image coordinate system of the image frame is subjected to rotation processing to obtain a mapped coordinate axis after rotation. Then, the first human body model is subjected to multi-angle rendering processing around the mapped coordinate axis to obtain a rendering result corresponding to the image frame. In this way, the multi-view rendering result of the three-dimensional human body model is rotated around the correct gravity direction, so as to avoid the rendering result of the three-dimensional human body model from being inclined.

FIELD: medicine.SUBSTANCE: group of inventions relates to a method for multi-frequency bioelectrical impedance analysis and a device for implementing it. Alternating electric current signals are passed through the human body. Each signal has one of three different frequencies. At each frequency, the amplitude of the voltage of the signals passing through the human body is measured. An initial phase angle is selected for each specific impedance module. The phase angle characterizes the phase shift of the current of signals entering the human body relative to the phase of the voltage of signals passing through the human body. At each frequency, the phase angle is estimated using an equivalent electrical model of the human body, the initial phase angle and the impedance modulus. A body model is created for a specific person. The ratio of extracellular water content to total body water content in a human is determined by inputting extracted parameters of the human body model into a trained machine learning model. The device comprises a source of alternating electric current signals, electrodes for conducting and reading signals, a measuring device for measuring signal parameters, a processor and memory.EFFECT: device is compact and has small-area electrodes for integration into wearable and / or portable devices while maintaining measurement accuracy.14 cl, 6 dwg
