Handheld LiDAR scanners are revolutionizing 3D data collection, offering professionals in construction, surveying, forestry, and infrastructure inspection a powerful tool to capture precise spatial data efficiently.

With numerous models available, choosing the right scanner can be daunting. This guide simplifies the decision-making process by highlighting the critical factors to consider, ensuring you select a device that meets your project needs.

Why Choose a Handheld LiDAR Scanner?

Handheld LiDAR scanners provide unparalleled flexibility and speed compared to traditional surveying methods. By emitting laser pulses and measuring their return times, these devices generate detailed 3D point clouds in real time, enabling applications such as:

• 3D Modeling and Design: Create precise digital three-dimensional models for architectural or engineering projects.

• Construction Monitoring: Track progress and verify structural integrity.

• Urban Planning: Map cityscapes for development and infrastructure planning.

• Forestry Analysis: Assess tree density, height, and terrain for environmental studies.

• Industrial Inspections: Inspect complex machinery or facilities with precision.

Key Considerations for Choosing a Handheld LiDAR Scanner

To ensure you select the best scanner for your needs, evaluate the following factors:

Accuracy and Precision

Accuracy reflects how closely the product’s measurements match real-world dimensions, while precision ensures consistent results across multiple scans. For applications like surveying or engineering, prioritize scanners with high accuracy and stable precision to maintain data reliability.

Resolution

LiDAR measures distance by emitting laser beams toward objects. However, the laser is not without size; it has a certain diameter. This laser forms a spot on the object, as shown in the figure below (captured by an infrared camera). The white dot represents the spot.

You can think of the laser spot as the resolution of the lidar, which is the same concept as the resolution of the image.

Below is a comparison of spots from different laser emitters. For other distances, the spot size can be calculated proportionally.

Scan Range

The scanner’s range determines its suitability for different environments. Short-range scanners (e.g., 10–50 meters) are ideal for indoor mapping or small spaces, while long-range models (100+ meters) excel in outdoor applications like infrastructure or forestry surveys. Match the range to your typical project scope.

Data points generated per second

This defines the level of detail in the point cloud, with higher data points per second capturing finer details for intricate models. However, higher data points per second generate larger datasets, requiring more processing power. Balance resolution with project requirements to optimize efficiency.

Portability and Flexibility

A lightweight, compact scanner enhances mobility, especially for fieldwork in remote or rugged locations. Look for devices under 2 kg with ergonomic designs to reduce fatigue during extended use, ensuring productivity without sacrificing data quality.

User Friendly

Intuitive interfaces, real-time visualization, and automated features like SLAM (Simultaneous Localization and Mapping) streamline operation and reduce training time. Look for scanners with one-click processing or seamless data transfer to enhance efficiency.

Durability

Fieldwork often involves harsh conditions, so opt for scanners with rugged designs, including dust- and water-resistance (e.g., IP54 or higher). Durable devices ensure reliability and minimize maintenance costs in challenging environments.

Cost and Value

Beyond the initial price, consider long-term costs such as software subscriptions, maintenance, and training. A scanner that balances performance with affordability offers the best return on investment for professionals.

Recommended Handheld LiDAR Scanner

What professionals truly need is a scanner that strikes the right balance of flexibility, high precision, long scanning range, and cost-effectiveness. An added advantage is when the device excels in specific aspects—whether it’s portability, data versatility, or workflow efficiency.
