The Basics of LiDar Technology

Module 3 - The Basics of Lidar Technology
In this module, we'll focus on the fundamentals of LiDAR technology with specific emphasis on the technical parameters of Zenmuse L1. By the end of the module, you'll know how to set parameters for multiple mission types, and different methods to successfully calibrate L1's IMU.
About the Zenmuse L1 Surveying course:
By the end of this course, you will understand the best practices used to obtain accurate data from your LiDAR surveys using the DJI Zenmuse L1 payload. You'll know everything from hardware preparation, mission planning, mission monitoring, data processing, sensor calibration, and more.
This course is proudly brought to you by DJI and Heliguy.

Where can I view the processed model?

[@patricklindahl868]

Why the annoying noise (music?) in the background?

[@MrDJC247]

That plus the narrators accent make it nearly impossible to concentrate.

A Question regarding the Field of View (Scanning Angle), the video states that the Repetitive as well as the Non-Repetitive scan modes (so BOTH modes), result in a narrower Vertical scan with a higher accuracy. This is at ~9min 05seconds on the video timeline. I'm guessing the narrator or his notes goofed. Can this be clarified please? Thanks!

Field of view (FOV), also known as the scan angle, represents the angle covered by the LiDAR sensor, or the angle at which laser signals are emitted. The FOV of L1 varies in different scan modes Repetitive scan: FOV 70.4°*4.5°. In this scan mode, the vertical field is narrower, but the accuracy is higher. This mode is recommended for high-accuracy surveying and mapping. Non-repetitive scan: FOV 70.4°*77.2°. In this scan mode, the vertical FOV is wider. This mode is recommended for data capturing of complex structures, such as building facades. Note: The effective range of L1 varies based on where the object is within the FOV. The closer to the edge of the L1's FOV, the shorter the effective range.

@@DJIEnterprise Thank you for the clarification! We've just purchased a 300 RTK and an L1 for the GIS Dept. of our College and I'm doing some of the prep work. I appreciate the solid reply :)

What is the accuracy of this LiDAR?

[@dsfs17987]

saw mentioned something about 5mm on another video about this system

[@hectorarruti1751]

@@dsfs17987 something about 5 cm !
