Abstract

The invention relates to the field of computer vision, and discloses a hand three-dimensional model reconstruction method and device, electronic equipment and a storage medium, which are used for improving the reconstruction efficiency of a hand three-dimensional model. According to the embodiment of the invention, the method comprises the steps of collecting a hand region of a target object through a single RGBD camera, and obtaining an RGB image and a depth image corresponding to the hand region; determining three-dimensional coordinate information of hand key points in the hand region according to the RGB image and the depth image; geometric calibration is carried out based on the three-dimensional coordinate information of the hand key points to obtain shape parameters of a hand geometric contour; extracting textures of the hand region from the RGB image to generate a skin texture map; and generating a hand three-dimensional model according to the shape parameters and the skin texture map. Because the hand three-dimensional model is reconstructed based on the single RGBD camera, the hand three-dimensional model reconstruction process is simplified; and the hand three-dimensional model generated by adopting the hand three-dimensional model reconstructed by the embodiment of the invention is more vivid and has richer details.

Description

technical field [0001] The present disclosure relates to the field of computer vision, in particular to a reconstruction method, device, electronic equipment and storage medium of a three-dimensional model of a hand. Background technique [0002] In recent years, due to the rapid development of three-dimensional sensors and three-dimensional application scenarios such as augmented reality (Augmented Reality, AR), virtual reality (Virtual Reality, VR), games and animations, the application of three-dimensional vision has gradually become popular. 3D modeling is an important application direction of computer vision. [0003] In fields such as AR, VR, games, and animation, it is necessary to reconstruct 3D animation from single-view or multi-view 2D images. In order to generate more realistic animations including the hands of characters and improve the user experience, it is necessary to construct a 3D model of the human hands. However, in the fields of AR, VR, games, and ani...
