First, the basic concept and function of the calibration board
A calibration board is a tool used to calibrate lidar systems, which helps improve the accuracy and reliability of liDAR systems by providing a reference point of known size and position. By scanning specific patterns or marks on the calibration board, the LiDAR system obtains accurate distance and Angle information to correct and optimize the system's errors. The function of the calibration board is not only to improve the initial accuracy of the system, but also to dynamically calibrate the system during operation to ensure the long-term stability and accuracy of the system.
In the robot industry, the application of calibration board is mainly concentrated in the following aspects:
Robot navigation: The robot uses LiDAR for environment perception and path planning, and the application of calibration board can significantly improve the positioning accuracy and navigation efficiency of the robot. Whether in the field of industrial automation or in the field of warehousing and logistics, accurate navigation and positioning are the basis for the efficient operation of robots.
Environment awareness: The calibration board can help the robot to better identify and perceive the surrounding environment, including obstacles, road signs, etc. This is essential for the autonomous navigation and obstacle avoidance function of the robot.
Path planning: With accurate calibration, the robot is able to generate more accurate and efficient path planning, which improves work efficiency and safety.
