Large-scale scene true three-dimension display rapid generation method based on computer generated hologram technology

The invention discloses a large-scale scene true three-dimension display rapid generation method based on a computer generated hologram (CGH) technology, comprising the following steps: (1) resampling a three-dimension data source to obtain 3D data of each entity in a target large-scale scene, and generating a 3D entity stereoscopic model by the utilization of the 3D data; (2) carrying out transformation of coordinates on the 3D entity stereoscopic model to generate 3D model description with a unified reference coordinate; (3) integrating depth-of-field information and texture information of an entity model into a 3D model to form a single-entity true 3D entity model; (4) synthesizing the single-entity 3D model to a position corresponding to the large-scale scene so as to form a large-scale scene 3D entity model; and (5) generating virtual display of the target large-scale scene through computer simulation. Through the computer generated hologram technology, rapid generation of a large-scale scene 3D entity v
