Laser scanning services can help any company or organization capture data of objects and environments. These services are essential for anyone who works in engineering, law enforcement, or other related fields.
Below we discuss some factors that businesses and organizations should consider before hiring a laser scanning service or buying their own laser scanning equipment.
High costs are the biggest drawback of purchasing your own scanner equipment. You might be able to get your scanning needs met with a hand-held laser scanner. A tripod-mounted, larger laser scanner could be required. This can add up to hundreds of thousands of dollar. A scanner can be a luxury if you run a profitable business that could easily offset the expense.
If you are a small- to medium-sized business that cannot afford an expensive laser scanner then hiring a laser scanning company may be the best decision. Laser scanning-equipment is costly, but the costs of services are quite affordable.
A laser scanner is not enough to fulfill all the scanning requirements of many businesses. Different laser scanners can be used for different purposes. You could end up spending millions to purchase the equipment you need, as well as the costs of training your staff and hiring skilled scanner professionals. If your company finds itself in this position, you can be sure that your outsourcing expenses will not exceed the cost of purchasing the equipment. Additionally, a laser scanning and digital twins services will take care of equipment maintenance and eventual replacement.
It’s not just the cost difference between scanning equipment and scanning services that drives companies to outsource their scanning needs. Important to note is whether or no company has the employees necessary to operate complex scanning equipment in an efficient, professional manner.
To make the purchase worth it, most companies will need to hire scanning professionals. If the equipment isn’t operated by professionals, it can be difficult to produce flawless data results in just one surveying session. It is better to hire a laser-scanning professional if your company is interested in purchasing scanning equipment, but not to increase staff.
Now, it’s possible to view any building in digital 3D via your computer. Laser Scanning and 3D Laser Scanning Surveying have made it possible to quickly process large amounts of data and produce precise representations for any building or object.
The basic idea is that when we view the world through our eyes, we collect huge amounts visual and spatial data. These data are then processed by the brain into 3D images.
Laser Scanning Surveying employs precisely the same processes. However, it uses more sophisticated machinery that gathers images, spatial, or geometric data, and a computer to do the processing.
This 3D database represents the scan environment in a very precise way. The ‘point cloud’ laser scanning data has a rigid geometric structure and can be used to benefit a variety of users.
This can be done by “bombarding” a building, rail, tunnel or road with millions of safe laser beam pulses in order to obtain precise measurement data. This is done using’state-ofthe-art’ equipment. These laser beam pulses are sent out by laser scanners and are reflected back to the laser scanner.
This simple procedure provides highly accurate XYYZ co-ordinates of any surface or object that the laser points have hit. These co-ordinates, when repeated millions of time, can then be processed with ‘3D Point Cloud Software’. They can then be exported to many different 3D software like revit and autocad.
It is a high tech process that yields amazing results. It can also be used anywhere a digital representation or reality could be helpful, not just in architecture.
There are many possibilities. These are just three areas where laser scanning may prove to be useful:
Accuracy: This process eliminates most of the human error that often leads to project complications. The laser scanner doesn’t get tired or make mistakes from a heavy workload. Therefore, the results it produces are more reliable as well as more accurate than standard surveying methods.
Speed – The ability to measure at 1,000,000 points per minute allows for a large amount of data to quickly be collected. Information can be accessed almost instantly, allowing for decisions to be made much faster than traditional surveying techniques.
Laser scanning allows people and teams to concentrate on their strengths. The third great benefit is that laser scanning frees them up to work on other parts of a project. They are no longer burdened with tedious calculations. This almost always results in better designs, happier employees and clients and improved end results.
3D Laser Scanning offers many more benefits than traditional techniques. This is why it is worthwhile to explore Laser Scanning Services for your business.
Laser scanning’s use has grown steadily since its introduction in the late 90’s. Although some industries may have a clear use for laser scanning, others might not. However, 3D scanning is still a valuable tool that provides a basic benefit to every user. It allows for the exact spatial data of any object or environment to be collected, which can then used in multiple data models for different applications.
If you are looking for a solution to collecting spatial data in any form, then 3D scanning might be the right choice. Four areas are benefitting from laser scanning right now to show the versatility of laser scanning.
Laser scanning, also known by laser surveying, became a popular tool for engineers. Engineers were immediately able to use it to incorporate design intent into the computerized models of products. They could also troubleshoot products and identify any small deviations (warping/under trimming, over trimming). You can also determine the product’s intended layout. 3D scanning provided engineers with a better method to reverse engineer products for a variety of reasons.
Like engineering, laser scanners have revolutionized geographical surveying. Construction companies and other entities needing land surveying no longer have to spend a lot of time surveying. Instead, they can complete a surveying project in a matter of hours. Laser scanning can be used to reduce the time it takes to survey.
The law enforcement seems to not have an obvious need for laser surveying. This is in contrast to the engineering and geographical surveying industry.
However, crime scene and accident investigators are often less able to determine the cause of an incident or how it happened without laser scanners. Along with recording all spatial data from a crime scene or accident scene, including bullet holes, laser surveying also allows investigators the ability to create crime scene/accident scene animations that are based upon hard data.
If a case goes to trial, animations will be useful in convincing jurors.
Laser scanning isn’t required in the field of historic preservation. Laser scanning can collect precise spatial data from objects of all sizes, which makes it an ideal tool to record the information of heritage objects for the purpose of restoration. Recent examples of laser scanners being used in preservation are the May 2010 scan of the Mount Rushmore Monument.
Laser scanning (also known by laser surveying) was introduced in 1998. It quickly became associated with the engineering industry and manufacturing. Laser scanning has been used in a variety of organizations since then, such as police departments and archeological society.
One example of laser surveying’s expansion over the past decade is the recent surveying at Mount Rushmore monument, May 2010. Surveying specialists scanned the huge sculpture to collect its surface information. The data will be stored and used in restoration efforts if the sculpture experiences gradual erosion or unexpected damage.
The 3D scanning system was shipped from Scotland. This situation is common in today’s scanning culture. Suppliers of surveying equipment and surveying companies regularly lend their support to cross-continental scanning efforts.
The expected rainfall in Mount Rushmore made it necessary to use water resistant scanning equipment. The project’s duration could have been significantly cut if time-of flight scanners were used. These scanners use a laser rangefinder for measuring surface data over long distances. Triangulation scanners are more accurate and have a narrower scanning range.
The Mount Rushmore sculpture was not only scanned, but the surveying crew also scanned the memorial area beneath it. This is for restoration purposes.
No matter the project’s scanning needs, all scanning projects must capture the exact physical information of the object, space, or surrounding environment. Three main advantages to 3D laser scanning systems over traditional surveying methods are that they cost less, take less time, provide more accurate results, and make it easier to store the information than reams 2D drawings. However many scanning service providers also offer 2D drawings of scanning data for customers who are interested.
Despite the obvious benefits of laser surveying over traditional mapping, some companies continue to be loyal to the former out of familiarity and because scan data is relatively new.
Most scanning providers provide scan data that is already in file types requested by customers. These may include polygon mesh or solid CAD models. Customers can edit and manipulate the data through a user-friendly interface. Some companies purchase their own scanning equipment. For those with a lower budget, renting scanning services is an option.
Laser scanning (also known as laser surveying) is often misunderstood to be a technology that has only one industry. However, 3D scan services are not only used in the engineering and manufacturing industry, but also many companies and organizations that would not be able to benefit from laser scanning.
This is because laser scanners can capture exact data about objects, environments, and places. Below are some examples of areas where 3D scanning is beneficial to entities that have not been traditionally associated laser surveying.
Worldwide police departments are using laser scanners to capture accident scene evidence and crime scene evidence. The laser scanners allow police officers to capture all physical elements of a scene or crime scene regardless its location. Investigators may not be aware of some of the details.
Not only can police gather valuable information, but laser scanners can also be used to accurately judge bullet trajectory using the location of bullet holes. Laser scanners also allow law enforcement officers to create 3D animations, which are based off scanning data and allow police to recreate an accident or crime in real time. These recreations can prove to be very valuable for either the defense or the prosecutor.
Archeological groups use laser surveying much like construction companies to map terrains for safety and find the best way to excavate.
However, archeological organisations also use laser scanning to document the physical data underground chambers and tunnels. They also use it to create virtual tours for historic areas where public tours would pose a danger to the integrity of the site.
Laser scanners are used to collect physical information about historical objects to help restore them to original condition after damage has occurred. Also, scan data could be used to make smaller models of historical objects for sale, such as Michelangelo’s David and Eiffel Tower.
One recent example of laser scanning used for restoration purposes was the May 2010 scan of Mount Rushmore and the memorial garden that lies below. In the event that the monument sustains severe damage or is subject to gradual erosion, the scans will help to restore it to its original form.
