Why SLAM LiDAR is Essential for Precision Mapping in Complex Environments

November 14, 2024

4 minutes read

The need for precise, efficient, and autonomous mapping has become essential in various industries. SLAM (Simultaneous Localization and Mapping) technology combined with LiDAR has emerged as a leading solution for high-accuracy 3D mapping in challenging environments. This article explains how SLAM LiDAR mapping works, its key benefits, applications, and why Exyn Nexys is setting a new standard in mapping technology.

What is SLAM LiDAR Mapping?

SLAM LiDAR mapping is a process that uses LiDAR sensors and SLAM algorithms to create real-time 3D maps while simultaneously tracking the device’s location within an environment. This capability is vital in settings where GPS may not be reliable, such as underground or densely built areas.

 

Here’s how it works:

 

LiDAR sends out laser pulses and calculates distances based on the time it takes for each pulse to reflect back, creating a dense map of the surroundings.


SLAM algorithms use these data points to continuously map the environment while recognizing previously mapped areas, enabling real-time mapping without relying on GPS.

What Benefits Does SLAM LiDAR Offer?

One of the primary advantages of SLAM LiDAR technology is its autonomy in GPS-denied environments. SLAM LiDAR can capture accurate data without relying on GPS, making it essential for mapping in enclosed spaces, underground sites, or areas with limited satellite visibility. This ability ensures that mapping can continue uninterrupted in places where GPS signals are weak or nonexistent.

 

SLAM LiDAR mapping also provides high accuracy and precision, combining SLAM algorithms with LiDAR technology to achieve survey-grade accuracy, often within a 5mm margin at a 1-sigma level. This degree of accuracy enables users to create highly detailed and reliable maps for various applications. Furthermore, modern SLAM LiDAR devices like the Exyn Nexys support real-time data processing and visualization, allowing users to view maps instantly and adjust scanning parameters as they go, optimizing data quality and efficiency.

 

The versatility of SLAM LiDAR across multiple platforms is another key benefit. Whether mounted on handheld devices, backpacks, drones, or ground-based robots, these systems can adapt to various configurations. This flexibility allows a single device to be deployed across diverse mapping scenarios.

How Drones Enhance Bathymetric Surveys: A Safer and More Efficient Approach
Bathymetric surveys, which involve mapping the underwater topography of lakes, rivers, oceans, and other bodies of water, have historically been conducted using traditional manned boats equipped with sonar systems. While effective, these methods can be time-consuming, expensive, and sometimes risky, especially in shallow, remote, or hazardous waters. However, drones or unmanned aerial vehicles (UAVs) and unmanned surface vessels (USVs) are facilitating bathymetric surveys by offering a faster, more efficient, and safer alternative.

What is a bathymetric survey?

A bathymetric survey measures the depth and topography of the underwater surface, providing a detailed map of the waterbed. These surveys are essential for a variety of industries, including environmental monitoring, coastal engineering, underwater construction, and scientific research. Traditional methods often rely on echo sounders mounted on boats or ships, but drones now offer new possibilities for bathymetric data collection.

Types of Drones Used for Bathymetric Surveys

There are two primary types of drones used in bathymetric surveys, Aerial Drones (UAVs) and Surface Drones or USVs:

Aerial Drones (UAVs)

Drone-Based Echo Sounder
EchoLogger ECT D052S Echo Sounder
These drones are typically used to collect aerial data or to assist in launching smaller surface drones. They can also be equipped with LiDAR sensors or photogrammetry systems to map the water surface. For example, the DJI M350 RTK, can be outfitted with devices like the EchoLogger ECT D052S, a high-performance dual-frequency echo sounder that measures water depths between 0.5 to 200 meters. This echo sounder comes equipped with tilt and temperature sensors and features an RS232 interface, allowing easy integration with drones. Its lightweight and durable design make it ideal for deployment in challenging environments, offering accurate underwater data collection for small to large-scale water bodies. The echo sounder provides a versatile, efficient solution for detailed underwater mapping without the need for traditional manned vessels.
