Laser ranging systems have been utilized in various industries for many years, with the first patented devices emerging in the late 1980s. The use of 3D scanning was initially introduced to the Architecture, Engineering, and Construction (AEC) sector in the 1990s when integrated commercial systems for 3D scanning process became available on the market. Since then, this industry has experienced rapid and significant growth. Early adopters recognized its value in capturing existing conditions within industrial plants, where inadequate documentation and complex equipment posed challenges for retrofits and maintenance. Over time, advancements in data storage and processing speeds have greatly improved the speed and quality of 3D scanning technology. These developments have directly influenced the enhancement of post-processing capabilities by making it faster and more powerful.
When scanning technology appeared, it brought with it the incredible ability to create detailed 3D models, revolutionizing data capture by allowing us to document details with precision, resulting in a digital version or a digital copy that faithfully replicates the physical object.
The value proposition for 3D scanning process goes beyond just improving surveying methods. It offers owners a powerful set of tools to achieve measurement goals that were previously unattainable, while also enhancing asset information management as a whole. Rather than replacing traditional total stations, 3D scanning complements them by providing additional capabilities. In fact, it is common practice to use a total station to establish a control network that connects scans together. With advancements in scan speed and quality, the cost of hardware and labor is decreasing, making the benefits of using 3D scanning technology for AEC applications more evident than ever before.
Scanning systems primarily capture the physical location of a target object by creating a series of points in Cartesian coordinates (XYZ), known as a "point cloud." This is achieved by comparing the emitted and reflected light pulse, allowing the scanning instrument to determine the position of the target object. The scanner calculates this position by measuring the angle of the scanner assembly (which includes both the scanner head and reflector) and determining how long it takes for light to travel from the scanner to the target object. This can be measured directly using time-of-flight scanners or indirectly using phase and light-based scanners.
The scanner also records the amount of reflected energy (measured as intensity) from the surface, which is influenced by the characteristics of the target surface and the surrounding lighting conditions. Most scanners are equipped with a camera (either built-in or separate) that can determine the color of each point using the RGB (red, green, blue) value scale commonly used in imaging. Since scanners rely on optical systems, they can only capture what is visible to them and cannot penetrate walls or other obstacles. This means that areas blocked by obstructions will appear as "shadows" in the captured point cloud where no data is available. The accuracy of physical data collected by scanners depends on environmental conditions during scanning, just like intensity and color data which may vary based on lighting conditions.
Measurement values are represented in a file format that includes the position, intensity, and color of each individual point in the point cloud. This data can be encoded using various point cloud file formats (such as ASCII, PTS, LAS, E57) which follow the XYZIRGB scheme for position-intensity-color. Different hardware and software vendors have their own proprietary formats but these can usually be converted to meet specific client requirements. It is advisable for clients to specify the desired file format based on how they plan to use the data when negotiating with service providers. This is particularly important if integrating the data into existing information management systems. To ensure compatibility with project needs, clients may opt for a non-proprietary standard archiving format like ASTM E57 File Format for 3D Imaging Data Exchange.
Mobile and aerial scanning systems, in which the scanner is mounted on a moving vehicle during the measurement process, gather extra data about the vehicle's movement to compensate for motion. A Global Navigation Satellite System (GNSS) detects the position and velocity of the scanner, while an inertial measurement unit (IMU) detects its attitude rate and acceleration. This information is recorded and processed while acquiring data, resulting in a point cloud file with adjusted physical positions. This allows project teams to efficiently capture data from the physical environment without needing multiple equipment setups. Additional data like environmental conditions during data capture and calibration/service provider information can also be linked to the dataset. Mobile and aerial scanning are increasingly becoming standard methods for creating digital city models, documenting road networks, tunnels, powerlines, and other large-scale infrastructure measurements.
Several factors can impact the accuracy of point cloud data, including the capabilities and calibration of the scanning instrument, as well as quality control measures. Environmental conditions also play a role, such as surface reflectivity, the angle between the scanner and target object (known as angle of incidence), and the distance to the target (which affects laser beam divergence). To ensure high-quality results, it is important for clients to establish functional performance requirements before acquiring field data. This allows them to work with 3D scanning service providers in determining the best instrument, scanning positions, and acquisition times that will yield optimal deliverables. While experts in controlling errors during scanning, there are some general guidelines that clients should be aware of to effectively develop their performance requirements.
3D scanning technology is a game-changer in various industries, from filmmaking to video game development and even virtual reality experiences.
