Abstract

The invention discloses a character animation drawing method and system based on motion tracking in a video, wherein the method comprises the following steps: the video containing character movement is obtained, and 3D scanning character models are obtained via 3D scanning in a standard posture; the 3D scanning character models are matched with preset standard templates, and therefore human body shapes and human body postures are obtained. When each frame is read in, an objective function is optimized according to the human body shapes and human body postures to match the standard templates with characters in the video, human body posture parameters can be obtained, and optimization of shape parameters can be realized; Kalman filtering is added to the character motions between different frames, so that the standard templates are converted back to the 3D scanning character models via corresponding matched points, and human skeletons are obtained to realize character animation drawing. This method can help effectively improve accuracy and reliability of animation production and has broad application prospects; the method is simple and easy to implement.

Description

technical field [0001] The invention relates to the technical fields of computer graphics and computer vision, in particular to a character animation drawing method and system based on motion tracking in video. Background technique [0002] Character animation drawing based on motion tracking is a very important problem in the field of computer graphics. Previously, character animation drawing based on motion tracking was based on multiple cameras or a depth camera, but this patent only needs a monocular camera to shoot The following video will do it. In addition, due to the marketization of kinect, the difficulty of scanning the static model of the human body is greatly reduced, but the dynamic use of the static model is still limited. The system provided by this patent is also a dynamic use method for the scanned 3D human body static model, which has great prospects in film production, virtual reality, game effects and so on. [0003] A large number of motion tracking me...
