A method of the basketball trajectory reconstruction
Lifang Wu, Shen Wei, Han Xiuli, Meng Xiang-long, Chao Liu · 2008
In this paper we proposed a method to reconstruct the basketball trajectory from 2D plane to 3D space. First we discuss the camera calibration and obtain the affine projection matrix. Estimation of the 3D coordinates from 2D coordinates is a morbid problem, in this paper we resolve it by the continuity of basketball trajectory. Finally, the 3-D scene of basketball court and the 3-D motion of the basketball are generated.
