LiDAR Scanners for the Mining Industry: LI Grip H300 and Hovermap STX



In the rapidly evolving world of mining technology, accurate mapping and navigation are paramount, especially in challenging environments like underground mines and GPS-denied areas. Two standout solutions in this field are the LI Grip H300 by GreenValley International and the Hovermap STX by Emesent. Both utilize cutting-edge SLAM (Simultaneous Localization and Mapping) technology but bring unique features to the table. This blog explores these handheld LiDAR scanners, comparing their capabilities, and examining how they can be used in the mining industry.



What is SLAM Technology

Both the LiGrip H300 and the Hovermap STX utilize SLAM technology, which allows for simultaneous navigation and mapping of the environment. This is crucial in areas where GPS signals are weak or nonexistent. The key to effective SLAM scanning is "closing the loop," ensuring the start and end points of the scan overlap to create a dense, accurate point cloud. This technology forms the backbone of both scanners' ability to provide real-time, precise mapping data.



LiGrip H300: Versatility and Integration

The LI Grip H300 incorporates a 360° LiDAR scanner, a data bank for storage and battery, and a 360° camera that automatically records during scans. Its integration with a mobile app enhances usability, allowing users to manage scans and monitor system status effortlessly. With up to 500 GB of storage, the LI Grip is well-equipped for extensive fieldwork.

A notable feature is its compatibility with drones, particularly the DJI M300, enabling aerial data collection in inaccessible areas. Moreover, the LiGrip shines in terrestrial scanning with easy GNSS data integration for precise geo-referencing, making it ideal for above ground stockpiles and infrastructure. [VD1] [VD2] 



Hovermap STX: Precision and Autonomy

The Hovermap STX matches the LiGrip in terms of LiDAR capabilities but stands out with its focus on autonomous navigation. Though it requires manual operation of its external camera, its internal data storage simplifies the management of collected data. The Hovermap's strength lies in its advanced autonomy when mounted on drones, providing partial automation for safe navigation in obstacle-dense environments like underground mines.

With an accuracy of ±1 cm, the Hovermap excels in indoor and underground mapping, where its SLAM-based navigation and obstacle avoidance capabilities allow for detailed, accurate point clouds. Its ability to integrate with the DJI M300 drone for autonomous flights enhances its utility in complex, hazardous environments.

Applications in the Mining Industry 

Both scanners are highly applicable to the mining industry but serve different niches. The LiGrip H300 is particularly effective in open, terrestrial environments where GNSS data can enhance geo-referencing accuracy. Its drone compatibility expands its utility to aerial surveys, making it versatile for both above-ground and difficult-to-access areas.

On the other hand, the Hovermap STX is the go-to for indoor and underground applications. Its autonomous navigation capabilities make it invaluable for mapping in tight, complex spaces where manual piloting is risky or impossible. This makes the Hovermap STX a critical tool for safety and efficiency in underground mining operations.



The LI Grip H300 and Hovermap STX handheld LiDAR scanners offer sophisticated solutions to the mining industry's mapping and navigation challenges. Whether it's the LI Grip's versatility and ease of integration with GNSS data or the Hovermap's precision and autonomous capabilities, both scanners provide invaluable tools for enhancing safety, efficiency, and accuracy in mining operations. As technology continues to advance, the potential for these scanners to transform the industry grows, highlighting the importance of embracing innovation in mining practices.
