the difference between aircraft aerial photography and drone aerial photography
Mar 22, 2022
Large aircraft Aerial photography has a large area, high Aerial photography efficiency and good image quality. Aerial photography is usually used for Aerial photography. The aerial camera is a measurement camera without lens distortion, and the image can be used for high-precision Aerial photogrammetry. The disadvantage is the high cost of Aerial photography.
UAVs can carry out small-area Aerial photography, are more flexible, and have low Aerial photography costs. They can be used for projects with low mapping accuracy. The disadvantage is that the Aerial photography efficiency is low, and it is not suitable for large-area Aerial photography.

Mar 18, 2022Aerial photography to understand
Aerial photography (Aerial photography), as a modern means of photography, can overlook things from a height that is difficult for people to reach, and convey a macro image to the audience from a completely liberated perspective, bringing a brand-new visual enjoyment. In recent years, with the development of television and flight technology, various methods of Aerial photography have been widely used in the production of films and TV documentaries. During the expo, helicopter Aerial photography was used many times to show the lively scene of the expo site. Today let's take a closer look at Aerial photography and learn its secrets. More > -

Monitoring of water pollutants
Aerial Remote sensing can monitor pollutant substances and detect water pollution problems in water areas through aerial Remote sensing; First to know about the Remote sensing, Remote sensing is to point to in the case of no direct contact with the target object, distance of target object detection, recognition and feature information, the process of electromagnetic waves, sound waves in space, gravity field can be used as a Remote sensing, but usually described in the Remote sensing refers to the use of electromagnetic waves for target feature information of Remote sensing of electromagnetic waves. Since any object with a temperature higher than absolute zero can emit, reflect or absorb energy radiation, and different objects have different properties and structures, different ground objects have their unique radiation characteristics. Similarly, in water environment monitoring, water bodies with different temperature, sediment content, algae quantity and pollution degree also have different radiation characteristics. Usually, the characteristics of various water bodies can be reflected by Remote sensing images. Polluted water has spectral characteristics different from clean water, which are reflected in the absorption or reflection of specific wavelength, and these spectral characteristics can be captured by Remote sensing devices and reflected in Remote sensing images. Based on the recognition of images, we can obtain water quality parameters or water pollution status. Based on this, Remote sensing technology can be applied in water environment monitoring. More > -
