### Drone-Based LiDAR: The Elios 3 Advantage
One of the standout features of the Elios 3 is its integrated LiDAR sensor, making it the only cage drone in the world equipped with this technology. This innovation enables versatile workflows across a range of applications, including confined space inspections, hard-to-reach area scans, and detailed 3D surveys.
The LiDAR on the Elios 3 serves three key functions. First, it enhances stability by working alongside the Visual-Inertial Odometry (VIO) cameras to track and compensate for the drone's movements. This is especially beneficial in dusty or visually obstructed environments where traditional visual tracking methods fall short.
Second, the LiDAR offers superior situational awareness. During data capture, the live map generated in the Cockpit app or post-flight in the Inspector app provides a dynamic view of your asset. This helps operators navigate the drone precisely, ensuring safe returns to the takeoff point and seamless integration of visual data with spatial coordinates back in the office.
Finally, the LiDAR plays a crucial role in surveying. By collecting precise data, the Elios 3 generates highly accurate and dense point clouds. These point clouds are instrumental in taking measurements, calculating volumes, and analyzing environments in intricate detail.

### Introducing the Surveying Payload for Elios 3
With the new payload, the Elios 3's LiDAR sensor has been significantly upgraded to the Ouster OS0-128 Rev 7, surpassing the standard configuration’s Ouster OS0-32 Rev 6.2. The new sensor boasts enhanced capabilities, offering improved accuracy, faster mapping speeds, and superior point cloud quality. Here's a closer look at what sets it apart:
#### 1. **Five to Ten Times Greater Accuracy**
The new surveying payload delivers up to five to ten times better accuracy compared to the standard configuration, with drift reduced to as little as 0.1% in structured environments. For instance, volumetric calculations are now accurate to within 1% of terrestrial laser scanners. This level of precision is ideal for demanding applications requiring centimeter-level accuracy, such as mining or civil engineering projects.
*“Almost 5 times more accurate in the z-axisâ€: The z-axis drift factor shows an improvement from 3.2% with the standard LiDAR to 0.7% with the Surveying Payload.*
#### 2. **Increased Mapping Efficiency**
With double the range (up to 100 meters) and four times the point density (1.3 million points per second), the new sensor allows users to cover twice as much area in half the time. This means simpler flight paths and fewer flights to complete large-scale projects.
*“Twice as much coverageâ€: Side-by-side flights demonstrate the Surveying Payload’s ability to map double the area in the same time frame.*
#### 3. **Superior Point Cloud Quality**
The new LiDAR sensor boasts 1.5 times better precision (+/-12mm) and 10 times better photon sensitivity than the standard configuration. These improvements translate into clearer, more detailed point clouds with sharper geometric definitions and truer-to-reality colorization. This results in enhanced overall definition and usability of the final point cloud.
*“Comparisonâ€: The first point cloud was created using the standard Elios 3 setup, while the second, crisper point cloud was generated with the Surveying Payload and FARO Connect software.*
#### 4. **Improved Robustness in Symmetrical Environments**
Traditional LiDAR sensors often struggle with symmetrical structures like pipes or wastewater tunnels due to limited geometrical variation. The new Rev 7 sensor overcomes this limitation, creating better point clouds even in these challenging environments. While accuracy varies depending on the specific conditions of the site, the overall quality remains consistent.
*“Symmetrical Environment Scanâ€: This LiDAR scan demonstrates the payload's ability to accurately map a narrow passage filled with pipes.*
#### 5. **Streamlined Processing**
In collaboration with FARO, the new Surveying Payload includes a software license for FARO Connect and reflective targets. This software automates the creation of clean, georeferenced point clouds, simplifies data alignment, and offers advanced filtering and export options. Users benefit from a seamless workflow that minimizes manual intervention.

### Choosing the Right LiDAR Payload
When deciding between the standard and surveying configurations, consider the specific requirements of your project. The standard LiDAR (Ouster OS0-32 Rev 6.2) is ideal for close-range visual inspections, providing sufficient accuracy for defect localization and navigation in complex spaces. On the other hand, the surveying payload (Ouster OS0-128 Rev 7 with FARO Connect) is tailored for projects demanding centimeter-level accuracy, such as underground mine surveys or detailed cave mapping.
Ask yourself: Do you need a highly accurate 3D model for critical decision-making, or are you primarily focused on situational awareness and visual data localization? If the former, opt for the surveying payload. If the latter, the standard configuration will meet your needs effectively.

Wood Industrial Knives
There are many types of knives used in the wood processing industry, and different blades are suitable for different wood processing links and requirements. The following is an introduction to several common knives used in the wood processing industry:
1. Circular Saw Blades
Function and application: Saw blades are the main tools used for wood cutting, usually used in conjunction with circular saws. They can be used to cut wood crosswise or cut wood longitudinally into boards or logs.
Material and design: Common saw blade materials include high-speed steel (HSS), carbon steel, and carbide (carbide steel). The design has different tooth shapes and numbers of blades according to different cutting requirements and wood types.
2. Planer Knives
Function and application: Planers are mainly used to plane the surface of wood to make it smooth. They are used in conjunction with planers or thickness machines for flattening wood.
Material and design: Planers are usually made of high-speed steel (HSS) or carbide, with high wear resistance and cutting efficiency. The design of planers includes different blade angles and numbers of blades to meet different processing needs.
Function and application: Wood chippers are mainly used to quickly and efficiently cut large or whole pieces of wood into wood chips or wood chips. They are widely used in the wood processing and papermaking industries to produce wood fuel, wood board, pulp, etc.
Tool design and material:
Chippers usually have a multi-blade design, and the blades are mounted on a rotating blade disc, so that the wood can be quickly cut on the blade disc and produce wood chips. Commonly used chipper materials include high-speed steel (HSS), cemented carbide (tungsten carbide), etc. These materials have good wear resistance and cutting performance, and are suitable for high-intensity wood processing.
