Which of the following is a method of ensuring the accuracy of LIDAR?

Calibration against known distances is essential for ensuring the accuracy of LIDAR systems. This process involves comparing the LIDAR measurements with measurements taken from a reliable reference point or an established distance that is known to be accurate. By determining how closely the LIDAR data corresponds to these accurate reference measurements, any deviations or inaccuracies can be identified and corrected. Regular calibration helps maintain the precision of the LIDAR system, allowing it to produce reliable data for applications in various fields such as surveying, environmental monitoring, and autonomous vehicle navigation.

While daily usage logs, regular maintenance checks, and routine operator training sessions contribute to the overall functionality and efficiency of the LIDAR system, they do not directly address measurement accuracy in the same way that calibration does. Usage logs might help track operational history, maintenance checks ensure that the equipment is in good working condition, and operator training enhances the effectiveness of data collection and interpretation. However, calibration specifically targets the accuracy of the measurements obtained from the LIDAR system, making it the key method for ensuring precision.
