The application of unmanned aerial vehicle remote sensing technology in archaeological research is gradually showing its unique advantages and potential. It not only provides high-quality 3D terrain data but also effectively detects underground relics, providing archaeologists with unprecedented perspectives and information. This article will discuss how unmanned aerial vehicle remote sensing technology assists in detecting underground relics in archaeological research.

Overview of unmanned aerial vehicle remote sensing technology

Unmanned aerial vehicle remote sensing is a technology that uses drones to carry sensors for high-resolution imagery and high-precision data collection on the ground. With technological progress, the application scope of unmanned aerial vehicle remote sensing in archaeological research is expanding, including terrain mapping, vegetation coverage analysis, terrain profile measurement, and underground relic detection.

The role of unmanned aerial vehicle remote sensing in detecting underground relics

High-resolution imagery acquisition: Drones can carry high-resolution cameras to obtain high-definition ground imagery, providing detailed ground information for archaeologists. By analyzing these images, potential relics under the surface cover can be discovered.

Terrain mapping and 3D reconstruction: Drones can collect high-precision terrain data, combined with terrain mapping technology, to generate detailed 3D terrain models. This not only helps archaeologists understand the overall structure of the site but also provides precise reference coordinates for archaeological excavation.

Vegetation coverage analysis: In some cases, vegetation coverage may conceal relics underground. By analyzing the vegetation coverage images captured by drones, archaeologists can identify areas with sparse or missing vegetation, which may hide underground relics.

Assisting in the detection of underground relics: By using sensors such as radar and LiDAR (laser radar) carried by drones, it is possible to penetrate the surface and detect underground structures. For example, LiDAR technology can generate high-resolution underground terrain maps, helping archaeologists identify hidden underground structures such as buildings, roads, and canals.

Application cases

In recent years, the application of unmanned aerial vehicle remote sensing technology in archaeological research has become increasingly common. For example, near Xi'an, Shaanxi, China, archaeologists have used drones for archaeological surveys and successfully discovered multiple ancient tombs that had not been excavated. These discoveries have provided important clues for understanding the distribution and layout of ancient tombs and also provided precise coordinates for subsequent archaeological excavation work.

Conclusion

The application of unmanned aerial vehicle remote sensing technology in archaeological research provides archaeologists with new perspectives and means. Through means such as high-resolution imagery, terrain mapping, vegetation coverage analysis, and underground structure detection, unmanned aerial vehicle remote sensing technology can effectively assist archaeologists in detecting underground relics and provide strong support for archaeological research. With the continuous advancement of technology, the application prospects of unmanned aerial vehicle remote sensing in the field of archaeology will be even broader in the future.
