Why do aerial surveys use five lenses?

Using 5 lenses can add high-quality UV lenses, which can improve transparency, high definition, small distortion and more realistic color reproduction.

The transformation of UAV aerial survey and traditional surveying and mapping technology lies in the difference of measurement methods. The aerial survey of UAV does not need to measure the human body on the spot, but directly measures the three-dimensional modeling results of UAV tilt photography data by using data acquisition software. The three-dimensional model obtained from aerial survey can be constructed into a real three-dimensional model with the same scale as the site and target coordinate system as needed. Through the computer, the data required by the project can be measured in the survey area, such as the integration of real estate, topography, road traffic, urban and rural planning and disaster prevention. At present, the data acquisition software mainly includes EPS geographic information workstation of Beijing Sunway Technology, SV360 intelligent three-dimensional mapping system of Diop, Hidata, easy mapping software and so on. The generated orthogonal model can also be directly loaded into ArcMap for measurement and drawing.
