A Method of Automatically Generating Virtual Terrain |
| abstract |
The invention discloses a method for automatically generating virtual terrain, which extracts characteristic curves from sketches and sample DEMs respectively to obtain sketch feature images and sample feature images; divides the sketch feature images into sketch blocks, and the sketch blocks The original small block of the sketch on the corresponding sketch; the sample feature image is divided into small sample blocks, and the small sample block corresponds to the original small block of the sample on the sample DEM, and the small block of the sketch and the small block of the sample are aggregated class analysis to obtain clustering results; according to the clustering results, the matching relationship between the original small block of the sketch and the original small block of the sample is obtained; the resulting terrain image is synthesized by using the matching relationship; the present invention utilizes the method of clustering to realize The automatic generation of virtual terrain is realized, and all the matching relationships can be established by one traversal of the small sketch blocks by using the clustering method, which avoids repeated searching of huge sample spaces, thereby improving the synthesis efficiency. |
