Augmented reality based scenario display method and system

The invention relates to an augmented reality based scenario display method and an apparatus. The method is performed through following steps: capturing a real scenario image at any time; determining the light source position information based on the position, time and data of the real scenario image; decoding the real scenario image; based on the decoded results, identifying from pre-set three-dimensional virtual models the three-dimensional virtual model that fits the real scenario image with the result of acquiring the virtual scenario and the touch information; and based on the three-dimensional virtual model that fits the touch information and the real scenario image, generating a three-dimensional virtual object. According to the invention, the generated three-dimensional virtual object raises interaction, allowing a user to observe a virtual world more directly. Second, according to the light source position information, location information, and inclination information, the shadowed part of the three-dimensional virtual object can be determined. When the real scenario image, the three dimensional virtual object and the shadowed part of the three dimensional virtual object are overlapped, it generates an augmented reality image about to be on display. Further more, the shadowed part makes a virtual scenario more pleasant to eyes and brings better user interaction experience.

Tile map data organization method

The invention relates to a tile map data organization method based on a nested pyramid model, belonging to the technical field of visualization of geographical spatial information. Additional similar models are penetrated into the existing pyramid model, wherein the ratio of line number to column number of sliced tiles of each layer is a constant, the magnification setting among layers is the same, the line number and the column number of the tiles of the first stage present an arithmetic progression relationship, so that a nested pyramid model with more compact dimensional transition is constructed. By laying emphasis on the reasonable setting of the dimensions of interpolation maps, the invention adopts a more exquisite and reasonable map dimension dividing manner to increase the dimension distribution density of spatial data, thereby preventing ground objects from being transited in an unsmooth way at the primary stage of dimension pull-down caused by the use of 2X magnification incase of organizing spatial data of small spanning dimensions, and preserving a spanning space for the detailed transition at the later stage. The invention is an improvement on the existing tile map data organization method, and is especially applicable to the organization of spatial data of small spanning dimensions.
