  • Publication number: 20250086826
    Abstract: This application provides a digital person training method and system, and a digital person driving system. According to the method, human-body pose estimation data in training data is extracted, and the human-body pose estimation data is input into an optimized pose estimation network to obtain human-body pose optimization data. Generation losses of position optimization data and acceleration optimization data in the human-body pose optimization data are calculated based on a loss function of the optimized pose estimation network, so as to minimize errors between position estimation data and acceleration estimation data and a real value. In this way, the optimized pose estimation network is driven to update a network parameter to obtain an optimal driving model that is based on the optimized pose estimation network. The errors between the position estimation data and the acceleration estimation data and the real value are minimized.

  • Patent number: 12094046
    Abstract: A digital human driving method and apparatus are provided which relate to computer and image processing, and can solve the problem of shaking, joint rotation malposition and partial loss of a digital human during a driving process. The solution includes: capturing video data from multiple angles of view in a real three-dimensional space by multiple video capture devices; determining a first coordinate of a key point of the target human; determining a mapping relationship based on the first coordinate; calculating a second coordinate based on the mapping relationship and the first coordinate; processing the second coordinate according to a key point rotation model to obtain rotation value of the virtual key point in the virtual three-dimensional space; and driving the digital human to move based on the rotation value of the virtual key point in the virtual three-dimensional space.
