Here are five typical applications for UAV LiDAR, though there will be others:ĭrones are helpful for the ongoing mapping and monitoring of forestry & agricultural operations. Capturing complex data and imagery has never been so easy. The way businesses survey is now more cost-effective, quicker, and superior to anything previous. Practical Applications for UAV LiDARĮven drones found on Amazon can exploit LiDAR technology. It can be within 1-2 cm when attached to drones equipped with GPS, digital cameras, and capable computers. You can expect somewhere in the neighborhood of one million distance points/sec. Many of the modern devices are capable of extremely high data rates. They have 360-degree visibility rotating around a dedicated axis. Today, we can attach LiDAR systems to drones and that’s a huge deal. A Game Changer in Mapping & Geospatial Data That’s not to say one is better than the other one-they’re just different, though similar. This is where UAV LiDAR has an edge over photogrammetry.īoth LiDAR and photogrammetry technologies have their advantages and disadvantages. For example, it’s not ideal for mapping below a tree canopy or other major obstructions. It’s not good for mapping elevations unless the ground is clear from every angle. Photogrammetry does have its disadvantages. It’s how we measure and view different objects in 3-dimensions. It’s a similar principle to how human eyes determine the perception of depth. It transforms 2D images into 3D cartometric models. Photogrammetry is passive technology and the science of making measurements from actual photos. Photogrammetry and LiDAR are both powerful technologies with similarities and differences. LiDAR can help to enhance results when combined with photogrammetry techniques. We’ll look into the practical applications further down the page. There’s a lot more to it than this but that’s the basics of how it works. It measures the reflection time of a signal from the object back to a detector. UAV (unmanned aerial vehicle) LiDAR scans the environment from above using a pulsed laser beam. LiDAR (short for Light Detection and Ranging) is a smart remote sensing technology.
