Handheld Portable Scanners

In the realm of LiDAR surveying, two prominent methods of positioning have emerged: Simultaneous Localisation and Mapping (SLAM) and Global Navigation Satellite System (GNSS).

Selecting between SLAM and GNSS solutions for LiDAR mapping depends on the specific requirements of the surveying project.

For indoor surveys, GNSS-denied areas, or for rapid, on-the-go mapping, SLAM technology provides an advantage. On the other hand, GNSS-based LiDAR offers native accurate absolute positioning and can benefit surveyors with multi-return capabilities.

Using a handheld 3D scanner offers several advantages over stationary or tripod-mounted scanners:

1. Portability: Handheld scanners are lightweight and compact, allowing for easy transportation and use in various environments, including confined spaces and outdoor locations.

2. Flexibility: Handheld scanners can capture data from multiple angles and positions, providing greater freedom and versatility in scanning objects of different sizes, shapes, and textures.

3. Speed: Handheld scanners enable faster data capture as they do not require time-consuming setup or alignment processes typical of stationary scanners.

4. Accessibility: Handheld scanners are more accessible to users without specialised training or expertise, making 3D scanning technology more widely available across industries and applications.

5. Real-time Feedback: Handheld scanners often provide real-time feedback on scanned data, allowing users to assess scan quality and make adjustments on the fly, resulting in more efficient scanning workflows.

6. Maneuverability: Handheld scanners offer greater maneuverability, allowing users to navigate around obstacles and capture hard-to-reach areas with ease, enhancing scanning coverage and completeness.

Yes, handheld 3D scanners are designed to be user-friendly and accessible, even for individuals without prior experience.

They offer a convenient solution for 3D capture and modelling.

Handheld 3D scanners are capable of achieving high levels of accuracy.

For instance, scanners from XGRIDS can obtain 1.2cm relative accuracy, 3cm absolute accuracy, and a horizontal accuracy of 0.015°.

Yes, handheld 3D scanners can be used for both indoor and outdoor scanning. Handheld scanners which use SLAM algorithms, such as solutions from XGRIDS, can also be deployed for underground mapping.

Their portability, versatility, and adaptability make them suitable for a wide range of environments.
