[0015] The present invention will be further described in detail below through the specific examples, the following examples are only descriptive, not restrictive, and cannot limit the protection scope of the present invention with this.
[0016] A method for quickly displaying a single model in a massive three-dimensional model of geographic information, the steps of the method are as follows:
[0017] (1) Establishment of massive 3D models of geographic information: use computers, computer graphics cards, digital cameras, and stereoscopic image measuring instruments to establish 3D models through manual collection of 3D frames of 3D targets of geographic information, and then map the 3D models obtained by digital cameras Massive 3D models of geographical information are produced by attaching them to the 3D stereoscopic model;
[0018] (2) Establishment of quick search unit: Divide the massive 3D model data of geographic information into several grids according to the geograp...
