Embodiment approach
[0115] In this embodiment, when the actual shooting is inconvenient, the server can also obtain the sample video by shooting the 3D model through the virtual camera, which improves the acquisition method of the sample video and reduces the difficulty of obtaining the sample video.
[0116] 302. The server acquires shape parameters and posture parameters of the sample object based on the sample video frame.
[0117] In a possible implementation manner, the server performs shape estimation and pose estimation on the sample object based on the sample video frame to obtain shape parameters and pose parameters of the sample object.
[0118] The above implementation manner will be described below through two examples.
[0119] Example 1. The server performs feature extraction on the sample video frame to obtain the sample video frame features corresponding to the sample video frame. The server performs regression processing on the features of the sample video frame corresponding to...

The invention discloses an image rendering method and device, equipment and a storage medium, and belongs to the technical field of computers. According to the technical scheme provided by the embodiment of the invention, when the image rendering model is trained, three-dimensional reconstruction is carried out on the sample object based on the shape parameter and the attitude parameter of the sample object, and the rendering parameter is determined based on the camera parameter, the shape parameter and the attitude parameter; the influence of the virtual camera and the sample object is considered when the rendering parameter is determined, the rendering parameter is better matched with the three-dimensional model of the sample object, the first target image is rendered based on the rendering parameter to obtain a first rendered image, and the image rendering model is trained based on difference information between the first rendered image and the sample video frame, therefore, the obtained image rendering model has higher image rendering capability.
Description
technical field [0001] The present application relates to the field of computer technology, and in particular to an image rendering method, device, equipment and storage medium. Background technique [0002] With the development of computer technology, the application of human body reconstruction technology is becoming more and more extensive. Human body reconstruction technology refers to the technology of obtaining a three-dimensional model of the human body based on two-dimensional videos or photos of the human body. Human body reconstruction technology is widely used in live broadcast and animation production. In other scenarios, for example, in a live broadcast scenario, the anchor can use human body reconstruction technology to transform his image into an animal. [0003] In related technologies, a depth camera is used to collect point cloud data of a human body, and human body reconstruction is performed based on the collected point cloud data. However, when renderin...
