UAV low-altitude photography measures large-scale image map production, orthophoto production, digital elevation model production, and DLG products provide high-resolution, clear image data sources for urban areas and planned areas, providing emergency protection for key areas and facilities. Three-dimensional digital modeling, at the same time, can dynamically monitor key areas of interest to meet the needs of urban informatization construction for various types of large-scale high-resolution basic geospatial data.
1. Provide high-resolution mapping products for urban planning areas
Beijing Tianlifa Group (micro-signal: bjtianlifa) believes that with the further development of urban informatization construction, the new urban planning and implementation of the urban area is very lacking in the region and the large-scale, high-resolution of the current situation. High-precision grid digital mapping products. At present, the resolution of high-resolution satellite images that have been transmitted has reached about 0.5 m, but it is still difficult to meet the large-scale mapping requirements of 1:500~1:2000. UAV low-altitude photogrammetry can provide high-resolution aerial photographs, orthophoto DOM, high-precision digital elevation model DEM, digital raster map DRG and digital line graph DLG for key areas.
2. Provide mapping support for emergency tasks
For emergency mission areas, intuitive image data is required as a reference, and the acquired images not only require higher resolution but also require real-time performance. The low-altitude platform of the drone has the characteristics of flexible and rapid take-off and landing. The digital sensor equipped with it can acquire high-resolution images. The orthophotos processed by photogrammetry can provide first-hand information for emergency mission command and planning.
3, 3D digital modeling
Beijing Tianlifa Group (micro-signal: bjtianlifa) believes that low-altitude photogrammetry of drones can be used to obtain high-resolution remote sensing images of multiple angles in cities or key areas, thus solving the "dead angle" that ordinary aerial photography and ground photography cannot capture. ". Use aerial photography to generate DEM and DOM, and extract building textures from images for 3D modeling. The building texture collection for 3D modeling is completed, and the traditional process of manually collecting the texture of the building by photographing the ground is omitted, and the three-dimensional modeling of the full photogrammetry mode is realized.
4. Dynamic monitoring of key areas
The current urban construction is changing with each passing day. It is necessary to dynamically manage the core areas of the city and the multiple construction areas scattered in the urban area. It is also necessary to continuously carry out large-scale scales for these areas as large as tens of square kilometers and as small as a few square kilometers. High-resolution, high-precision grid mapping data is regularly updated. Utilizing the low-altitude aerial photography system of the UAV, the key targets can be dynamically monitored, and the change detection results can be obtained by automatically comparing the DSMs of different periods. The DOM and the results of the change detection are combined to obtain an intuitive detection result.
