Top Handheld 3D Laser Scanners Recommended by Measur

A handheld 3D laser scanner is a portable device that captures detailed three-dimensional data of objects or environments by emitting laser beams and recording their reflections. In architecture, these scanners enable the creation of accurate as-built models, facilitating precise design and renovation. In surveying, they enhance data collection with high-resolution, detailed topographical maps, improving accuracy and efficiency. In construction, they streamline site surveys, monitor progress, and ensure quality control by providing comprehensive, real-time data. This transformative technology allows professionals to achieve new levels of accuracy and productivity, fundamentally improving traditional workflows.

SLAM (Simultaneous Localization and Mapping) technology is a technique that allows handheld 3D scanners and other autonomous systems to build accurate 3D models of their surroundings while tracking their own position within that space. By continuously capturing data from sensors such as LIDAR or cameras, SLAM algorithms process this information to create a real-time map of the environment. This capability is crucial for handheld 3D scanners as it enables users to capture detailed spatial information and create precise 3D models even when moving through complex or cluttered spaces. The real-time mapping and localization ensure that the resulting models are both accurate and comprehensive, reflecting the true layout and features of the scanned area.

High accuracy and precision ensure that the 3D models reflect true measurements and details, which is critical for making accurate design decisions, conducting precise surveys, and verifying construction progress. For architecture, this means fewer errors in design and better integration of new and existing structures. In surveying and construction, it ensures that measurements are reliable. 

General Benchmark: 10 mm

The accuracy measures how closely the scanner’s captured data matches the actual dimensions. Higher accuracy is essential for detailed and precise work.

Large-scale projects, such as construction site surveys, may benefit from a wider range. In contrast, detailed architectural work may focus on shorter, more precise scanning distances.

General Benchmark: 1 - 200+ m

Real-time visualization provides immediate feedback during scanning, allowing users to see and adjust their work as it progresses. This feature is particularly useful for ensuring data completeness and accuracy on-site, reducing the need for rework.

 A scanner that is easy to handle and transport enhances user efficiency and comfort, especially during prolonged use or when working in tight or challenging spaces. Portability ensures that the scanner can be used effectively in diverse locations without causing fatigue or logistical issues. Opt for a handheld 3D laser scanner of ≤ 3 kg with an ergonomic design.

Efficient data processing capabilities and integration with other software streamline the workflow by allowing for quick and seamless data analysis and model creation. This is essential for incorporating the scan data into design, mapping, or construction software, reducing processing time and increasing productivity.

A durable and well-constructed scanner withstands the physical demands of fieldwork, such as exposure to dust, moisture, and rough handling. This ensures long-term reliability and performance, minimizing the risk of equipment failure and reducing maintenance costs.

Benchmark: IP54 or higher (dust and water resistance)

Longer battery life allows for extended scanning sessions without interruptions, which is essential for covering large areas or complex projects. Effective power management ensures that the scanner remains operational throughout the work period, enhancing productivity and reducing downtime.

Benchmark: ≥ 4 hours of continuous operation

Comprehensive training and robust customer support facilitate the effective use of the scanner by providing users with the knowledge and assistance needed to operate the equipment efficiently. This support helps in quickly resolving issues, optimizing the use of features, and ensuring that users get the most value from their investment. Look for the availability of tutorials, manuals, and responsive support services to assist users in effectively utilizing the scanner and resolving any issues.

Nexys is perfect for complex 3D mapping tasks, offering fast and accurate data capture in diverse environments, from urban landscapes to rugged terrains.

Using a handheld 3D laser scanner involves a systematic approach to ensure accurate and efficient data capture. The workflow begins with preparation and setup, including checking the equipment, calibrating the scanner if necessary, and assessing the scanning environment. Once the scanner is ready, planning the scan involves defining objectives, selecting appropriate scanning parameters, and positioning the scanner correctly. During the scan, the operator moves the scanner methodically while monitoring real-time data to ensure comprehensive coverage.

After the scanning is complete, the next steps involve post-processing the captured data. This includes reviewing the data for completeness, processing it into a 3D model using the scanner’s software, and exporting the final model for analysis. Final checks and reporting are essential to verify the model’s accuracy, document the process, and prepare detailed reports or presentations based on the 3D model.

2. Position yourself and the scanner in a stable and well-lit environment.

3. Calibrate the scanner according to the manufacturer's instructions.

4. Start scanning by moving the scanner smoothly and steadily across the target surface, ensuring proper coverage.

5. Review and optimize the scanned data using software for processing and refining the 3D model.

• Ensure proper lighting conditions to avoid reflections and shadows.

• Maintain a consistent and controlled scanning speed.

• Overlap scan paths for better data fusion and coverage.

• Use positioning targets or markers to aid in registration and alignment of multiple scans.
