With the rapid development of technology, airborne LiDAR technology has become one of the key technologies in modern surveying, remote sensing, navigation and other fields. As an important component of this technology, the airborne LiDAR calibration board plays a crucial role in ensuring the accuracy and stability of the radar system. This article will explore the application and importance of airborne LiDAR calibration boards from multiple fields.

1、 Surveying and mapping field
In the field of surveying and mapping, airborne LiDAR technology is widely used in terrain measurement, urban 3D modeling, and other fields due to its high accuracy and efficiency. The airborne LiDAR calibration board is the key to ensuring the accuracy of surveying data. By calibrating the high-precision reflection characteristics of the calibration board, precise calibration of the radar system can be achieved, thereby obtaining more accurate terrain data and urban 3D models. This is of great significance for urban planning, transportation construction, disaster monitoring and other fields.

2、 Remote sensing field
Remote sensing technology, as an important means of obtaining modern spatial information, is widely used in fields such as resource investigation, environmental monitoring, and disaster warning. The airborne LiDAR calibration board also plays an important role in the field of remote sensing. By calibrating the radar system, the accuracy and stability of remote sensing data can be improved, providing more accurate data support for resource investigation and environmental monitoring. At the same time, the calibration board can also help achieve precise identification and positioning of targets, providing strong support for disaster warning and emergency response.

3、 Navigation field
Navigation technology is an important support for modern transportation, military and other fields. The airborne LiDAR calibration board also plays an important role in the navigation field. By calibrating the radar system, the accuracy and stability of the navigation system can be improved, providing strong support for precise navigation of aircraft, drones, and other aircraft. In addition, the calibration board can also help achieve precise identification and positioning of ground targets, providing strong support for military reconnaissance and strikes.

4、 Other fields
In addition to the aforementioned fields, the airborne LiDAR calibration board also plays an important role in many other areas. For example, in the field of agriculture, calibration boards can be used to accurately measure farmland terrain and crop height, providing data support for precision agriculture; In the field of forestry, calibration boards can be used for forest 3D modeling and tree species identification, providing strong support for forest resource management and protection; In the field of environmental protection, calibration boards can be used to monitor air pollution and terrain changes, providing data support for environmental protection.

In summary, as an important component of modern airborne LiDAR technology, the airborne LiDAR calibration board is increasingly widely used in various fields. By improving the accuracy and stability of radar systems, calibration boards provide strong support for fields such as surveying, remote sensing, and navigation, promoting rapid development in these areas. In the future, with the continuous progress of technology and the expansion of application fields, airborne LiDAR calibration boards will play an important role in more fields and make greater contributions to the development and progress of human society.

The LiDAR calibration board can be used for target distance calibration of LiDAR, allowing LiDAR to more accurately determine surrounding faulty objects and their motion trajectories. The reflectivity commonly used for LiDAR calibration includes 10%, 50%, and 90%. If high calibration accuracy is required, more stepped reflectivity can be customized. The reflectance of the diffuse reflection standard plate can be selected from 1-99%, and different diffuse reflection plate sizes and shapes of 0.05m-3m or more can be customized, all of which have nearly perfect Lambertian characteristics and stability, allowing for optimal testing results in LiDAR calibration.

  • The research team has solved decades long challenges in the field of microscopy

    When observing biological samples under a microscope, if the medium in which the objective lens is located is different from the sample, the light beam will be interfered with. For example, when observing a water sample with a lens surrounded by air, the light bends more strongly in the air around the lens than in water.This interference can cause the measured sample depth to be smaller than the a...
