Drone LiDAR Accuracy Demo (Bridge Inspection)

Watch my latest video where I showcase the power of drone-based LiDAR technology for bridge inspection. Achieving groundbreaking accuracy with the ROCK R3 Pro LiDAR on a DJI M350 drone, we compare it to traditional survey methods in a must-see case study.


Highlights:

🎯 Top Accuracy: A stunning 0.49 cm standard deviation in LiDAR data, against 141 check shots.
🚁 Drone Magic: Manual flights with a newbie pilot, capturing crisp 3D point clouds.
🏗️ Mission Critical: Testing drone LiDAR for precise bridge girder inspection.

Nice video. Your non-zero mean suggests a small bias on the high side. Were you ever able to find and resolve the source of it? Removing any systematic error would, of course, shrink your SD.

How high(in meter) above ground did the drone fligh?

Woooo this is instinct amount accuracy . I request you to start a video series were you teach advance laidar technology like this. 🙏

Correct me if I'm wrong, but those aren't girders. You are referencing the concrete barriers on the bridge's deck. Girders, as you referenced in the photos, are below the deck and would not be visible from an aerial top-down LiDAR collection.

Any precision is possible with unlimited money and resources . Heres a challenge: Use 1 or 2 smartphones and their video data out of a moving car and get the coordinates of trees at the street with a precision of 10 cm. Whats realy relevant is the relation between money + time + n-data points + precesion

Survey crew chief/drone pilot here, born in 80'. I have been using GNSS systems at survey companies since 2008. Seeing what you have achieved with the R3 V2..man I'm getting misty over here. You and the team are outstanding. Harrison thank you for the amazing content on YT, as well as the courses on the Rock Robotic website. The passion and professionalism you guys are bringing to the table has a value that I do not see matched often. Please keep pushing the industry forward!
