The H1 Handheld 3D Laser Scanner combines LiDAR SLAM and integrated GNSS technology to deliver fast, accurate, and georeferenced 3D reality capture. Designed for efficient mobile mapping, it enables users to quickly generate dense point clouds and digital site documentation with minimal setup, making it well suited for construction, infrastructure, and other dynamic surveying applications.

In this project, the H1 was deployed to monitor the progress of a construction site in Culiacán, Mexico. By capturing a complete georeferenced 3D representation of the approximately 2,000 m² site in a single survey, the project team was able to remotely review construction progress, improve supervision efficiency, and reduce the need for frequent site visits.

1. Project Overview

• Project Type: Construction and progress monitoring

• Location: Culiacán, Mexico

• Objective: Generate updated spatial information for monitoring the progress of the construction work

• Duration: In Progress

2. Challenges

• Frequent travel for the contractor was required to inspect construction progress.

• Site updates were difficult to share efficiently with remote project teams.

• Traditional documentation methods could not provide fast, comprehensive 3D records for progress tracking.

3. Solution

3.1 Hardware:

• H1 Handheld 3D Laser Scanner

3.2 Key Capabilities

H1 Handheld 3D Laser Scanner:

• Combine LiDAR SLAM with GNSS for georeferenced point clouds in one workflow.

• With the integrated 3.9’ AMOLED touchscreen and onboard real-time point cloud viewer, users can monitor scanning progress.

• The 360° × 63.5° field of view minimizes blind spots and efficiently captures complex construction environments.

• Weighing only 900 g with an IP65-rated metal housing for demanding field conditions.

• Dual battery grips and external power support enable uninterrupted scanning.

3.3 Why H1 Handheld 3D Laser Scanner?

The H1 solution offered a fast and stable solution by combining LiDAR SLAM and GNSS positioning in a single handheld system. This allows the team to rapidly capture dense, georeferenced 3D point clouds.  Its portability, real-time visualization, and rapid data acquisition made it ideal for frequent construction progress documentation and remote project supervision.

4. Project Execution

The monitoring project was completed through the following steps:

4.1 Site Preparation & H1 Configuration

The survey began with a quick system setup, including project configuration, RTK initiaization and system synchronization. Once the configuration was complete, H1 was ready to capture accurately georeferenced point cloud data throughout the scanning process.

4.2 Rapid LiDAR Data Capture

By walking through the area that needed to be documented while holding the H1, the operator surveyed approximately 2,000 m2 of the construction site in less than 10 minutes, capturing dense 3D point cloud data in a single scanning session. Its handheld design and LiDAR SLAM capability allowed the site to be documented quickly without interrupting ongoing work.

Scanning Procedure

4.3 Point Cloud Processing

After the scanning, data were exported directly from the H1 into processing software, where they were cleaned, aligned, and adjusted to generate an accurate georeferenced point cloud for further analysis. The integrated GNSS antenna ensured that the point cloud already carried precise coordinates, reducing the need for additional georeferencing steps.

5. Results

The H1 enabled rapid digital documentation of the construction site, producing a georeferenced 3D point cloud for progress monitoring. With accurate and up-to-date spatial data readily available, the project team could supervise construction remotely, significantly reducing travel requirements between the headquarters and the job site. The resulting digital record also provided a reliable basis for progress comparison, project documentation, and more efficient construction management.

6. Customer Quote

The survey of approximately 2,000 m² was completed in less than 10 minutes using the H1 SLAM system. Considering the travel times and costs between La Paz and Culiacán, as well as the field inspection and documentation activities, the solution made it possible to have up-to-date information on the project in a single workday, avoiding recurring trips by technical personnel and significantly reducing the time associated with on-site monitoring.
