Case Study: Advanced Measurement Solution for Mine Tunnels and Air Raid Shelters with SHARE SLAM S10

SHARE

1. Project Overview

Surveying underground spaces like mine tunnels and air raid shelters presents unique challenges due to their confined nature, poor lighting conditions, and the difficulty in obtaining precise measurements in GNSS-denied environments. Traditional surveying methods, such as total stations, often fall short in terms of speed, precision, and efficiency, especially in complex and hard-to-reach locations. The SHARE SLAM S10 Handheld LiDAR System is a cutting-edge solution that addresses these issues, providing an advanced, accurate, and efficient approach for surveying and mapping underground infrastructures.

2. Challenges in Traditional Methods

Traditional surveying methods, such as total stations, face significant challenges:

- Slow Data Collection:Time-consuming setup and field measurements extend survey durations, impacting project timelines.

-GNSS Signal Limitations: Traditional GNSS-based systems cannot function accurately in GNSS-denied environments like mine tunnels or air raid shelters.

- Complex Data Conversion: Manual data processing and coordinate transformation increase the likelihood of errors and delays.

- Limited Access in Confined Spaces: Poor lighting and cramped environments hinder the accurate use of conventional surveying tools.

- High Technical Expertise Required: Operating and processing data from traditional instruments necessitate highly skilled personnel.

3. The SHARE SLAM S10 Solution

The SHARE SLAM S10 provides an innovative solution to these challenges by integrating cutting-edge technologies designed to operate efficiently in difficult underground environments.

-LiDAR and SLAM Technology Integration

The SHARE SLAM S10 uses LiDAR to generate high-precision 3D point clouds of the environment with a relative accuracy of 1?cm. This allows for the detailed capture of underground structures and features that would otherwise be difficult to measure with traditional methods.

SLAM Technology: The integration of SLAM allows the S10 to map and localize without relying on external positioning systems like GNSS. SLAM uses real-time data to create and update 3D maps, which are continuously refined as the user moves through the environment.

-Real-Time Data Processing

The device generates high-definition point clouds at a rate of up to 200,000 points per second, providing incredibly detailed models of the surveyed area.?The S10 enables real-time processing of LiDAR data, which can be immediately visualized into color point cloud which can be?integrated into CAD software. This reduces the need for post-processing, cutting down the time and resources required for data conversion and analysis. It also eliminates the risk of human error during the data entry process.

-Compact?and Flexibility

Weighing just 1.01 kg, the S10 is a lightweight, handheld device that can be easily maneuvered in narrow or hard-to-reach underground spaces such as mine tunnels and air raid shelters.?Built with a rugged design, the S10 is resistant to dust, humidity, and harsh environments, making it well-suited for long-duration use in challenging conditions.

4. Case Study: Shandong Province Mine Tunnel

In a Shandong Province mine tunnel project, the S10 LiDAR system was used to scan and generate a 3D model of the tunnel. Compared to traditional total stations, the S10:

-Delivered equivalent accuracy with 50% faster survey time.?

-Enabled?direct?CAD integration,?streamlining the design process and reducing post-processing.

5. Conclusion

The SHARE SLAM S10 Handheld LiDAR System offers an efficient, reliable, and precise?solution for underground surveying, particularly in GNSS-denied environments like mine tunnels and air raid shelters. By combining LiDAR technology with SLAM, it provides accurate 3D mapping, real-time data processing, and increased operational efficiency, making it a valuable tool for professionals in the construction and infrastructure industries.
