The team at GeoCue and Microdrones are constantly fielding questions about choosing the right LiDAR sensor, drone integration, and workflow to yield successful results. To help you get a better understanding of drone LiDAR here are some commonly asked questions on the applications, benefits, limitations, and more of Drone LiDAR.
1. What is drone LiDAR and how does it work?
Drone LiDAR involves mounting a LiDAR sensor onto a drone to capture precise measurements of distances and elevations. LiDAR sensors emit laser pulses and measure the time it takes for the pulses to return after hitting objects. By analyzing the reflected pulses, the sensor generates highly accurate 3D point clouds of the environment.
GeoCue is well known for its TrueView 3D Imaging Systems product line, which offer innovative UAV LiDAR and photogrammetry solutions integrated into lightweight payloads, that can be mounted on any platform capable of carrying the weight of the sensor.
Microdrones provides fully integrated drone systems. such as the EasyOne, that includes the aircraft, sensors, workflow, service, and support to help you work smarter.
2. What are the main applications of drone LiDAR technology?
Drone LiDAR finds applications in numerous fields, including surveying and mapping, infrastructure inspections, agriculture, forestry, urban planning, and disaster management. It enables efficient data acquisition over large areas, even in challenging terrains, providing valuable insights for decision-making processes. Here’s an example of TrueView Sensors being used for Land Development:
3. What are the advantages of using drone LiDAR compared to traditional LiDAR systems?
Drone LiDAR offers several advantages over traditional LiDAR systems. First, it provides flexibility and accessibility by reaching areas that are difficult or dangerous for ground-based surveys. Second, it significantly reduces data collection time and costs by automating the process and covering larger areas in a shorter span. Third, the ability to capture data from different angles and altitudes enhances the quality and detail of the output. Here’s a 3 minute case study showing the differences between traditional and drone surveying methods.
4. How accurate is drone LiDAR in capturing elevation data?
Drone LiDAR systems offer impressive accuracy levels, typically within a few centimeters. The accuracy can be influenced by various factors, including the quality of the LiDAR sensor, flight parameters, and the data processing techniques employed. It is essential to calibrate and validate the data to ensure reliable results.
LP360 LiDAR & photogrammetry 3D point cloud software can help you achieve the best results in processing your LiDAR and photogrammetric data. It’s been the professional choice in geospatial data processing software, made in the U.S.A. for 20 years. Here’s an example of how a professional use uses LP360 to classify data for a project on a steep hillside of a river bank with thick vegetation.
5. What are some factors to consider when choosing a drone LiDAR system for a specific application?
When selecting a drone LiDAR system, several factors should be considered. These include the required accuracy level, range and point density requirements, payload capacity and flight endurance of the drone, compatibility with data processing software, ease of integration, and cost considerations. Evaluating these factors in relation to your specific application will help you choose the most suitable system.
