Calibrating a UAV LiDAR system is an essential step to guarantee accurate data collection. Boresight and band alignment calibration are two of the most common methods used to correct misalignments between adjacent stripes in the raw point cloud. This process is necessary for obtaining reliable results from the LiDAR Geo-MMS system. The process of calibrating a UAV LiDAR system starts with the preparation of the system. This includes setting up the hardware and software, as well as configuring the settings to ensure optimal performance.
Once the system is ready, data can be collected and analyzed. The analysis should include an assessment of the misalignments between adjacent stripes in the raw point cloud. Once the misalignments have been identified, boresight and band alignment calibration can be used to correct them. Boresight calibration involves adjusting the orientation of the LiDAR system to make sure that it is pointing in the right direction. Band alignment calibration involves adjusting the position of each stripe in relation to its neighbors to make sure that they are all aligned correctly. The frequency with which a UAV LiDAR system needs to be calibrated depends on several factors, including the environment in which it is being used and how often it is being used.
Generally speaking, it is recommended that a UAV LiDAR system be calibrated at least once every six months. However, if the system is being used in an environment with rapidly changing conditions, such as a construction site, then more frequent calibrations may be necessary. Calibrating a UAV LiDAR system is an important step for obtaining accurate data collection. By following these steps, you can ensure that your UAV LiDAR system is providing reliable results.
