It’s a similar principle to how human eyes determine the perception of depth. It’s how we measure and view different objects in 3-dimensions. Photogrammetry does have its disadvantages. It’s not good for mapping elevations unless the ground is clear from every angle. For example, it’s not ideal for mapping below a tree canopy or other major obstructions. This is where UAV LiDAR has an edge over photogrammetry.īoth LiDAR and photogrammetry technologies have their advantages and disadvantages. 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. Today, we can attach LiDAR systems to drones and that’s a huge deal. They have 360-degree visibility rotating around a dedicated axis. Many of the modern devices are capable of extremely high data rates. You can expect somewhere in the neighborhood of one million distance points/sec. It can be within 1-2 cm when attached to drones equipped with GPS, digital cameras, and capable computers. Practical Applications for UAV LiDARĮven drones found on Amazon can exploit LiDAR technology. The way businesses survey is now more cost-effective, quicker, and superior to anything previous.

Capturing complex data and imagery has never been so easy. 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. Civil engineers and surveyors can benefit too. They’ll rely on UAV LiDAR as they plan to build the towns and cities of our future. Drone LiDAR can quickly collect data for infrastructure surveys. Best of all is that they can do this with zero disruption to people and services. Laser scanning is such a practical way to help improve mine and quarry safety as well. In turn, it can help to boost the efficiency of these type of operations. The built-in signal processing of high-end LiDAR sensors is vital for safe structural inspections. The large field of view (FOV) and multi-segment measurements produces crucial distance data and creates effectual obstacle detection. Here’s a breakdown of a typical LiDAR setup: LiDAR surveys cost money but it’s not a one-off cost. The unmanned aerial vehicle (UAV) or drone.
