HANDHELD SLAM LiDAR SURVEY & 3D MAPPING

Highlight Project | LaoEarth Geospatial Engineering

Fast • Accurate • Efficient 3D Reality Capture for Engineering, Mining, Construction & Infrastructure


HIGHLIGHT PROJECT

Project Overview

Handheld SLAM (Simultaneous Localization and Mapping)
is an advanced mobile LiDAR technology that captures millions of laser
measurements while continuously tracking the scanner’s position,
delivering accurate three-dimensional spatial data in real time.

✓ Millions of Laser Points
✓ Real-time Position Tracking
✓ No GPS or Tripods Required
✓ Engineering-grade Accuracy

Unlike conventional surveying methods, Handheld SLAM enables rapid
mapping of complex, confined, and GPS-denied environments while
producing dense point clouds for measurement, terrain analysis,
and digital mapping.

LaoEarth delivers complete geospatial solutions including 3D point
clouds, terrain models, orthophotos, engineering mapping, and digital
twins for infrastructure, construction, mining, and industrial projects.

Handheld SLAM Reality Capture

3D Reality Capture

Using a handheld LiDAR scanner, millions of laser points were collected while walking through the project corridor. The SLAM algorithm continuously calculated the scanner position to generate a high-density 3D point cloud representing the entire environment.

Key Features

✔  High-density Point Cloud

✔  Real-time Mapping

✔  No GPS Required

✔  Rapid Field Survey

✔  Complex Structure Documentation

Orthophoto & Survey Control

Orthophoto Mapping

Survey control points (GCPs) were established to verify positional accuracy. High-resolution orthophotos provide a geometrically corrected image that can be used directly for mapping, planning, and GIS applications.

Applications

• Engineering Design

• Topographic Mapping

• GIS Database

• Asset Management

• Infrastructure Planning
