And its manufacturing cost is becoming lower and lower, and the application is becoming more and more extensive. Unmanned aerial vehicle (UAV) is an important means to obtain aerial photography and surveying and mapping data, which arose in aerial photography in 2012. Now it has been widely used in reconnaissance, agricultural plant protection, surveying and mapping, and power line patrol. It has the advantages of real-time image transmission, detection of high-risk areas, safety and convenience, and low cost, high resolution, flexibility and other advantages. Based on the above characteristics, UAV-assisted technology is rapidly spreading to various industries. At present, the highway industry is mainly applied to highway maintenance and traffic monitoring, and is also changing the traditional construction management mode at a rapid speed for highway construction.展开更多

Unmanned aircraft is small in size and flexible in mobility. It does not need a dedicated runway to take off and land. It is little affected by weather and airspace control, and can quickly acquire images in a very short period of time. Research using unmanned aircraft for the aviation image of topographic map surveying and mapping, the image for difficult areas and need a quick mapping areas has important practical significance, its characteristics of fast and current, which will be in city planning, construction of digital city, national emergency disaster relief, geographical monitoring the state of the union, the new rural security and engineering of surveying and mapping surveying and mapping to play a positive role. However, the UAV aerial survey system carries a non-measurement camera, which has a large optical distortion and cannot be directly used in surveying and mapping production. It can only be used in digital photogrammetry system after distortion correction.展开更多

Compared with the field measurement technology, the application of UAV tilt measurement technology in real estate surveying and mapping work has greatly improved the accuracy, timeliness and work efficiency of surveying and mapping work. However, in the large-scale graphic surveying and mapping work, the traditional UAV tilt measurement technology requires the field adjustment and painting of eaves and editing after correction, which also leads to the increase of production cost.展开更多

The three-dimensional model is used to interpret the earthquake damage on buildings in the mega-earthquake area in order to acquire different-level house damage in the Kuzirun village disaster area. In addition,the characteristics of seismic damage on typical buildings are analyzed. The results show that the main collapsed houses in the mega-earthquake area are sand-stone buildings,of which about 39% are sand-stone buildings. Several brick-wood buildings and brick-concrete buildings are seriously damaged,while the buildings with frame structures are mainly slightly damaged,and the houses near the macro-epicenter of the earthquake are all in good conditions. Three-dimensional tilt photography technology can vividly display the scene of earthquake disaster,and can provide significant demonstration in building damage degree together with detailed analysis of disaster situation.展开更多
