Rapid mobile mapping: the benefits of handheld LiDAR scanning (SLAM 100) for complex sites in Vancouver

In the dynamic and often structurally complex landscape of Vancouver's built environment, traditional methods of site measurement are increasingly proving inadequate for the speed and precision demanded by modern construction and renovation planning. The industry now requires a solution capable of generating highly detailed, accurate spatial data efficiently. This imperative has solidified the position of mobile LiDAR scanning in Vancouver as the leading methodology for reality capture. Handheld devices, such as the SLAM 100, deliver exceptional 3D laser scanning services, turning complicated, feature-rich sites - from sprawling high-rise developments to intricate Victorian heritage homes - into quantifiable, actionable data, including highly accurate floor plans, elevations and site plans.

The technological edge: how SLAM revolutionizes mobile LiDAR scanning in Vancouver

LiDAR (Light Detection and Ranging) technology uses laser pulses to measure distances and create precise 3D point clouds of spaces, assets, and objects. While LiDAR systems have long been essential instruments in surveying, the revolutionary development was the creation of portable and lightweight handheld devices. These portable LiDAR scanners integrate sophisticated algorithms, marking a significant leap in efficiency, speed, and accuracy for building documentation.

The core of this efficiency lies in the technology known as Simultaneous Localization and Mapping (SLAM).

Defining SLAM: localization and mapping in real-time

SLAM is a transformative technology that allows mobile systems to simultaneously build and update a map of their surrounding environment while precisely determining their location within that map. Originally developed for robotics, SLAM has been successfully implemented across various surveying applications, ranging from handheld scanners and backpack systems to vehicle-mounted and drone applications.

Handheld laser scanners equipped with SLAM technology capture detailed 3D maps in real-time. These scanners measure distances using laser beams to create point clouds that represent the environment. The SLAM algorithms continuously process this data to identify unique features and landmarks, constantly updating the map as the operator moves. This continuous feedback loop ensures that the scanner accurately maintains its location within the mapping system, even when navigating complex and dynamic settings.

The best mobile mapping systems utilize a combination of LiDAR and RGB cameras to capture a densely colored, photorealistic 3D dataset of the structure. This data is intuitive to navigate, explore, and measure, even for stakeholders unfamiliar with traditional point clouds. Crucially, leading mobile mapping devices provide real-time feedback via a tablet display, showing the quality of the capture as the work is being performed. If an area is missed, the screen immediately indicates this, allowing the operator to correct the scan on the spot.

Superior accuracy in challenging environments

Handheld SLAM systems offer high precision, making them valuable tools for obtaining precise and accurate data with minimal effort. The output of sophisticated SLAM technology can be highly detailed 3D point clouds, with a point spacing density comparable to terrestrial laser scanning (TLS), sometimes reaching 2 mm spacing.

The SLAM 100, specifically, delivers impressive results, achieving:

• Relative accuracy: up to 2 cm.

• Absolute accuracy: up to 5 cm.

These systems are capable of producing georeferenced survey-grade accuracy after post-processing and geo-referencing, typically ranging from 6-15 mm for absolute accuracy depending on the environment and processing method. This level of precision is critical for professional applications such as LOD 300 BIMs or floor plans rendered at a scale of up to 1:50.

Handheld SLAM vs. terrestrial laser scanning: a workflow comparison

For complex sites and large assets, the adoption of handheld SLAM LiDAR is driven primarily by efficiency gains relative to traditional static Terrestrial Laser Scanning (TLS).

Comparison of key features:

• Mobility: handheld units easily navigate tight, complex, or hard-to-reach areas, whereas TLS is typically stationary.

• Setup time: SLAM devices are designed for rapid deployment and dynamic movement, unlike TLS which requires multiple setups and calibration.

• Data capture: handheld devices allow for rapid mobile mapping, capturing massive data swathes on the go.

• Real-time output: SLAM provides immediate 3D visualization and mapping feedback during the scan, while TLS data registration is typically performed after field work.

The most compelling argument for adopting mobile LiDAR scanning in Vancouver is the dramatically reduced time required on-site.

GPS-independent mapping: conquering urban canyons

A significant benefit of SLAM-based laser scanners is their ability to survey effectively in environments where Global Positioning System (GPS) signals are degraded or entirely unavailable. SLAM systems function independently of GPS.

This makes mobile scanning in Vancouver ideally suited for challenging regional infrastructure and properties, including:

• Indoor spaces and basements: SLAM systems perform real-time mapping in enclosed spaces where GPS is unavailable.

• Tunnels and underground spaces: the SLAM 100 has been used for capturing data in underground spaces and metro tunnels, eliminating the need for splicing operations.

• Urban canyons: in dense urban areas like downtown Vancouver, high-rise buildings often hinder GPS signals, but SLAM maintains accurate localization.

• Industrial facilities: complex manufacturing plants often have obstructed views and challenging geometries.

Furthermore, LiDAR-based SLAM systems are capable of operating with little to no light, making them perfect for inspections or surveying hard-to-reach areas during off-hours.
