Abstract
Provided are an initial view angle control and presentation method and system based on a three-dimensional point cloud and a point cloud system. A three-dimensional media stream is read and parsed. An initial viewpoint, a normal vector and a forward direction vector in the three-dimensional media stream are parsed. A user can view an initial angle, that is, a region of interest, designated by a content producer when initially consuming three-dimensional media content. Moreover, scaling, that is, scale transformation, of the three-dimensional media content is allowed in an optimized manner. In a real-time interactive scene, the view range of the user can be adjusted based on the position of the user relative to the initial viewpoint. The freedom degree of visual media consumption is fully improved according to the interactive behavior of the user, providing an immersive user experience.
