Which Elios 3 LiDAR payload is right for you? The Standard vs Surveying configurations
On October 11th, 2023, Flyability unveiled a groundbreaking Surveying Payload for their flagship Elios 3 drone, elevating flying mobile scanning to unprecedented levels. This new payload is bundled with the Elios 3 drone, the advanced Ouster OS0-128 Rev 7 LiDAR, and a FARO Connect software license. This article will explore the key specifications of the new payload and how it enhances the Elios 3's surveying capabilities. We'll also guide you through choosing between the standard and surveying packages depending on your project requirements.
### Drone-Based LiDAR: The Unique Elios 3
One of the standout features of the Elios 3 is its integrated LiDAR sensor. It's the only cage drone in existence to carry a LiDAR, enabling efficient workflows in tight spaces, hard-to-reach areas, and 3D surveys. The LiDAR plays three crucial roles: enhancing stability, providing situational awareness, and aiding in detailed surveying.
- **Stability:** The LiDAR works alongside VIO cameras to sense and compensate for the drone's movements, especially useful in environments with heavy dust.
- **Situational Awareness:** During data capture and post-processing, the LiDAR helps create real-time maps, making navigation easier and safer.
- **Surveying:** By collecting data via LiDAR and processing it with a powerful SLAM algorithm, the Elios 3 generates highly accurate and dense point clouds for precise measurements and analysis.
### The New Surveying Payload for Elios 3
The latest payload upgrades the Elios 3's LiDAR sensor to an Ouster OS0-128 Rev 7, surpassing the standard Elios 3 configuration's Ouster OS0-32 Rev 6.2. This upgrade significantly enhances the drone's surveying capabilities across multiple dimensions.
#### Key Upgrades:
1. **Enhanced Accuracy:** The new surveying payload offers up to five to ten times better accuracy (up to 0.1% drift in structured environments), ensuring models closely match reality. For instance, volumetric calculations are now accurate within 1% of terrestrial laser scanners.
- *Improved Z-Axis Drift:* From 3.2% with the standard LiDAR to 0.7% with the new payload, this results in almost five times better precision in the vertical axis.
2. **Increased Mapping Efficiency:** With double the range (up to 100 meters) and four times the point density (1.3 million points per second), users can cover more ground faster and with fewer flights. Projects that once required multiple passes can now be completed in a single flight.
- *Twice the Coverage:* Side-by-side comparisons show double the mapped area with the new payload.
3. **Superior Point Cloud Quality:** The new LiDAR boasts 1.5 times better precision (+/-12mm) and ten times better photon sensitivity, leading to clearer and more detailed point clouds. Geometric shapes are sharper, colors are truer to life, and the overall definition of the point cloud is improved.
- *Point Cloud Comparison:* The first point cloud generated using the standard LiDAR lacks the clarity of the second, which was captured with the new Surveying Payload.
4. **Better Handling of Symmetrical Environments:** Traditional LiDARs often struggle in symmetrical spaces like pipes or tunnels. The new Rev 7 handles these environments more effectively, producing superior point clouds with minimal errors, even in complex geometries.
5. **Streamlined Processing:** The Surveying Payload comes with a FARO Connect software license and reflective targets, allowing for automated creation of clean, georeferenced point clouds. Features include data alignment, filtering, and simplified export options, making post-processing more efficient.
### Choosing Between Standard and Surveying Configurations
Deciding between the standard (Ouster OS0-32 Rev 6.2) and surveying (Ouster OS0-128 Rev 7 with FARO Connect) payloads depends on your project goals:
- **Standard Configuration:** Ideal for close-up visual inspections of industrial assets. If your focus is on defect localization and navigating complex spaces, the standard LiDAR provides adequate precision.
- **Surveying Configuration:** Best for high-accuracy projects requiring centimeter-level precision. This setup is perfect for surveying sewer pipes, underground mines, or any challenging terrain where safe human access is limited. It also detects physical variations down to 1 cm (0.39 inches).
To decide, consider your deliverables. Do you need a highly accurate 3D model, or are you simply aiming for situational awareness? For the former, opt for the Surveying Payload; for the latter, the standard LiDAR suffices.
