The laser radar calibration panel is mainly used for the calibration and calibration of lidar. Its main role is:
Determine the measurement accuracy and performance metrics of LiDAR. By using the calibration board, the accuracy of the lidar's parameters such as ranging, angle, and velocity, as well as its performance indicators such as measurement error and uncertainty, can be evaluated.
Correct LiDAR measurement errors. Lidar may be affected by environmental factors (such as temperature, humidity, air pressure, etc.), as well as its own device errors, assembly errors, signal processing errors, etc., which will lead to errors in the measurement results of LiDAR. By using a calibration plate for calibration, these errors can be identified and corrected, improving the measurement accuracy of the lidar.
Establish the coordinate system of the lidar. Lidar measurements are usually represented in its own coordinate system, which may be different from the coordinate system of the actual application. By using the calibration plate for calibration, the conversion relationship between the coordinate system of the lidar and the coordinate system of the actual application scenario can be established, so as to realize the correctness and reliability of the lidar measurement.
Monitor the performance of lidar. Over time, the performance of lidar may change, such as decreased measurement accuracy, slower signal processing, etc. By regularly using calibration plates for calibration, you can monitor the performance changes of the lidar and identify and solve potential problems in a timely manner, so as to ensure the normal operation and reliability of the lidar.
In conclusion, the LiDAR calibration board is a very important part of the LiDAR system, which can help ensure the measurement accuracy and performance indicators of LiDAR, and improve its measurement accuracy and reliability.
