| titleOfInvention | Method and device for improving precision of digital elevation model |
| abstract | The invention discloses a method for improving the precision of a digital elevation model, comprising: S1: obtaining SRTM digital elevation model and Landsat 8 satellite remote sensing multispectral image data; S2: obtaining a reference digital elevation model of a predetermined area, and extracting the SRTM digital elevation of the predetermined area Model and Landsat 8 satellite remote sensing multispectral image data, with the SRTM digital elevation model data and Landsat 8 satellite remote sensing multispectral image data of the predetermined area as input, and the reference digital elevation model data of the predetermined area as output, training to obtain the artificial neural network model , the accuracy of the reference digital elevation model is higher than that of the SRTM digital elevation model; S3: Using the artificial neural network model and the Landsat 8 satellite remote sensing multispectral image data, the SRTM digital elevation model in S1 is improved. The invention also provides a device for improving the precision of the digital elevation model. The cost of the invention is controllable, and the accuracy of the digital elevation model can be improved effectively, in a large area and greatly. |
