Benefits Of Reality Capture And Why You Should Use It

Reality capture is a highly transformative technology that bridges the gap between the physical world and computer-based models. This rapidly evolving technology is creating a seismic shift in how different type of projects are approached, from design to execution. In this article, we delve into the benefits of reality capture and why you should use it.

At its core, the term “reality capture” refers to the process of capturing a physical asset surveyed in its current state and translating that into a digital format to create a virtual 3D representation that is often photorealistic. The process is very fast in comparison to other methods of creating virtual 3D models, saving money and time.

Using hardware such as laser scanners, drones equipped with cameras or lidar equipment, reality capture is able to collect vast amounts of data about the physical world.

This could be any asset, from a building, construction site, an infrastructure system or any other physical entity, such as a car, artifacts or construction site.

The reality capture data is then processed using software, such as our very own REBIM® tool, to accurately create 3D models, that can then be used in various applications ranging from design visualisation to asset management.

Different Reality Capture Data Capture Methods Available

Using reality capture technologies really helps revolutionise the way we document, analyse and recreate physical environments and it is easy to see why it is quickly becoming an indispensable part of project workflows.

The field of reality capture is enriched with a range of technologies that offer distinct capabilities and uses for project managers and professionals.

As these tools continue to advance, they offer even greater potential for various industries, from construction and archaeology to entertainment and virtual reality.

Let’s explore some of the specific types of reality capture solutions available and how the technology can be used.

Laser Scanning and 3D Laser Scanning

Laser scanning involves directing a laser beam at surfaces to measure distances. This data is then compiled to create detailed and highly accurate 3D models, often referred to as “point clouds”.

3D laser scans offer an even more detailed capture using precise measurements, allowing professionals to visualise intricate details, analyse accurate information and understand the nuances of a structure, site or object.

Photogrammetry and Drones

By analysing multiple images taken from different angles, photogrammetry allows teams to create accurate 3D models and maps. This method is widely used in fields such as surveying, archaeology and urban planning.

For example: Drones equipped with high-resolution cameras fly over a site, taking numerous overlapping photos.

These photos are then stitched together using software to create valuable 3D models or BIM models of the captured area, enabling a bird’s-eye view of the environment or job site and aiding in project planning.

Lidar Technology

Lidar (Light Detection and Ranging) uses light in the form of a pulsed laser to measure variable distances to the Earth.

The resulting data can then be used to make digital 3D representations of the target.

360° Reality Capture

This involves capturing the environment in a full 360-degree view using specialised cameras.

It gives stakeholders a comprehensive perspective, allowing them to virtually “walk the site” and view site conditions from every angle.

How Accurate Is Reality Capture?

The accuracy of reality capture in the construction industry and other sectors is highly reliable, subject to the quality of the software and hardware used.

This technology transforms raw data from 3D scans and mobile mapping into valuable, actionable information, accurately reflecting the as-built data and conditions of a project or site.

For example, in construction, this accuracy is vital for planning, design validation and ensuring that the built structure aligns with its design specifications.

Typically, the precision of 3D scans in reality capture can vary depending on the equipment used. High-end scanners, such as the Leica BLK range offer incredibly detailed captures, often to the millimetre.

This level of detail is crucial in the construction industry for detecting discrepancies early in the building process, thereby saving time and resources.

For example, comparing 3D scans of a building under construction with its design model can reveal structural deviations or inconsistencies that might otherwise go unnoticed until they become costly problems.

How Is Reality Capture Data Processed And Utilised?

The processing and utilisation of reality capture data, encompassing scan data, capture images and geospatial datasets, represent critical stages in transforming raw data into valuable digital assets. This process is fundamental across various fields, including architecture, engineering and urban planning.

Initially, reality capture involves collecting scan data and images using technologies such as 3D scanners, drones and photogrammetry.

This scan data typically consists of millions of data points that create detailed representations of physical spaces or structures. In construction and engineering, this accurate site data is pivotal in creating a Building Information Model (BIM) or a digital twin of a structure.

Once the scan data is collected, it undergoes processing through specialised reality capture software applications.

This software stitches the captured data together, converting vast point clouds and capture images into coherent, detailed 3D models or geospatial datasets.

These datasets are then often integrated into CAD software such as REBIM® software, enabling stakeholders to interact with and analyse the asset in a virtual environment, leading to improved efficiency and informed decision-making.
