Technological innovation can usually be divided into leap and semi-leaps.Leap is a huge step forward. Integrated circuits or microchips are a good example. It can hold billions of individual transistors, more than any other 20th century technology, which paved the way for the impressive computer power we take for granted today. In contrast, the multi-megapixel growth produced by smartphone cameras or software upgrades is only one and a half steps, which is a gradual improvement.
Leap and half jump are important partners. If we just take a leap, then change will become too fast, and unplanned elimination (relative to planned elimination) will dominate. On the other hand, if we are only half left, the change is too slow, and we are still bragging about transistor radios.
Only a proper balance between revolution and development makes sense. Therefore, for the 3D laser scanning industry (expected to reach US$4 billion by 2025) and AEC professionals who are increasingly dependent on these cutting-edge technologies, the next step is to expand on-site mobile scanning and more traditional static methods. embrace.
As with any incremental progress, the transition from static 3D laser scanning to mobile 3D laser scanning also takes time. It has also conducted a lot of research and development, greatly increasing mobile computer processing and cloud-based data sharing.
The mobile scanner is driven by advanced software, can be directly imported into any CAD system with 3D point cloud function, and can optimize the scanning of BIM workflow. It is an ideal choice for large construction companies, general contractors, and facility and factory managers. The built model and building documentation, while ensuring unparalleled quality control of the building.
Profit potential
There are two types of advanced mobile scanners today: handheld devices and scanners mounted on wheeled tripods, small vehicles or carried as part of backpack equipment. Operators can walk at a comfortable pace and quickly scan indoor spaces. Although mobile 3D scanning is mainly limited to industrial-grade use, Apple's iPad Pro 2020 LiDAR scanner (compatible with the Measure app) is an example of this technology's expanding range and lower prices.
No matter which route the company chooses, 3D mobile scanning can bring similar direct benefits:
• Since the camera is installed, it is possible to capture color images while scanning. This means that the color 3D point cloud is ready for immediate application, saving time and money.
• On-site flexibility means exploring narrow spaces and hard-to-reach spots, which will be difficult to capture with static scanning. Since there is no need to set up or reposition the scanner, it also saves time and money.
• Mobility allows the operator to avoid other site disturbances, such as people and debris. With mobile scanning, you can return to the site without waiting hours to capture previously inaccessible data.
• Compared to their cousins, handheld scanners are easier to use and have a faster learning curve. Speed up team work by reducing support staff, which means more time to complete the work.
• Enhanced functions can communicate with customers about site roaming faster and reduce the number of people on the site in a socialized way.
These benefits come at an important moment, as AEC professionals want to improve end-to-end efficiency and reverse the two (and possibly three) disturbing trends revealed by McKinsey’s analysis. In the Digital Future report of the consulting firm Imagining Construction, it found that the completion time of large construction projects is usually 20% longer than planned, while the cost is 80% higher than budget. It also found that construction productivity in certain markets has declined since the 1990s, and static 3D laser scanning has only just gained widespread use.
At a time when the health and safety of on-site personnel becomes a top priority, it is crucial to complete the work as soon as possible. This is also related to simple economy and return on investment: if static scans that previously took hours to complete can now be completed 10 times faster, the acceptance of new services will be faster than ever.
Hybrid solution
Whether in North America, Europe (estimated to reach US$2 billion by 2022), the largest market for 3D laser scanning, or in the fastest-growing Asia-Pacific region, there are new businesses.
However, as with any emerging technology, a cost-benefit analysis is usually performed. For industries that use 3D scanners, there is a competition between extreme speed and extreme quality. Yes, today's mobile scanners are fast, but they still cannot capture more data points per second than static scanners.
One way to solve this challenge is for companies to invest in a hybrid approach: a mobile scanner that can switch between mobile mode and static mode. As the best of both worlds, users can quickly scan large indoor spaces, such as factories or airplane hangars, and then upgrade or repurpose them. Moreover, it can also capture finer details of pipeline equipment, for example, it can scan 2m points per second through a fixed operation.
As a result, the final capture operation, which usually takes an hour or more to complete a static scan, can be completed in just six minutes. The decline is as high as 90%. By switching between static and mobile use cases, companies can maximize their efficiency while increasing their return on investment.
Leapfrog scanning
Therefore, whether you want to expand the office space and require the use of existing 3D digital images as the owner of the office space, or restore the historic building to the original blueprint, or plan to rebuild your office building, in the hospital, move 3D Digital scanning is increasingly becoming a fast and economical choice in various industrial applications.
For companies seeking more advantages, mobile scanning (and its mobile and static hybrid alternatives) may be an ideal investment.
Semi-leaping innovation may not always be front page news. But in the words of American essayist, playwright, novelist and civil rights leader James Baldwin (James Baldwin): "If you can change the way people view reality, even a millimeter, you can change the world."
