Embodiment

[0045] This embodiment is implemented under the Windows 10 64-bit operating system on the PC, and its hardware configuration is processor Core TM i5-7500 3.4GHz CPU, 8GB memory, the software environment is Matlab 2015b, the programming uses Python language, combined with the visual open source library OpenCV 2.4.4 and the open source raster spatial data conversion library GDAL.

[0046] This embodiment includes the following specific steps:

[0047] Step 1: Build the dataset

[0048] (1) Prepare elevation data block

[0049] Download the elevation data block J of the WGS84 coordinate system from the SRTM website http: / / srtm.csi.cgiar.org and store it in tiff format. The spatial resolution is between 90m×90m and 200m×200m. The height is denoted as H A , build a grayscale image G according to the height information of J: the highest point corresponds to white, the lowest point corresponds to black, and the interpolation between the highest and lowest point is gray; the re...

Abstract

The invention discloses a terrain synthesis method with multi-scale detail fusion, and the method employs a terrain data block of a digital elevation model (DEM), employs a deep learning strategy withmulti-scale detail fusion, and can customize a terrain with realistic details according to a sketch input by a user.

Description

technical field [0001] The present invention relates to terrain synthesis technology in the field of virtual simulation, in particular to a terrain synthesis method for multi-scale detail fusion, which utilizes terrain data blocks of Digital Elevation Mode (DEM for short), adopts salient feature sub-network and multi-scale The detail fusion sub-network builds a deep learning network; in the terrain synthesis, according to the user's hand-drawn sketches, combined with the input elevation data, using the pre-learned salient features, the deep learning strategy of multi-scale detail fusion is used to customize the terrain with realistic details . Background technique [0002] Terrain in virtual simulation is the main visual element in 3D scenes. Due to its wide application value, terrain synthesis technology has become a research hotspot in the field of computer vision. At present, terrain synthesis technology can be roughly divided into the following categories: procedural-ba...
