The History of Laser Scanning

Laser scanning services can benefit any company or organization that needs data to be captured about objects and environments. It is a must-have for all entities, including engineering firms and sheriff’s departments.

Below are some things companies and organizations should consider before they hire a laser-scanning provider or buy their own 3D scanner.

It is possible to spend a lot on your scanning equipment. A hand-held laser scanner might suffice for your scanning needs. However, it is possible to purchase your own equipment. However, a larger tripod-mounted laser scanner can easily run into the hundreds of thousands. The cost of a scanner and 3d scan may be worth it if your business is profitable and you can easily offset the purchase.

However, if your company is small or medium-sized and cannot afford a costly laser scanner, hiring a service to scan documents may be the best choice. Laser scanning equipment is expensive but laser scanning services can be accessed at a very low cost.

It’s not easy for many companies to meet their scanning needs by simply purchasing one laser scanner. Different laser scanners have different uses, so if you need multiple scanners for various purposes, you might end up spending millions. This is not counting the cost of training staff and hiring experienced scanner professionals. If your company is in this situation, it’s likely that your outsourcing costs will never be comparable to the cost of the scanning equipment. You don’t need to worry about equipment maintenance or replacement when you use a laser scanning company.

Scanner equipment costs versus scanning services aren’t the only consideration that companies consider when outsourcing scanning. Notable is the ability of employees to operate complex scanning equipment efficiently and professionally.

Most companies who decide to buy their own scanner equipment need to hire skilled scanning professionals in order to make the investment worthwhile. Scanning equipment that is not operated by professionals can easily fail in delivering its main selling point: perfect data results in as few as one surveying session. An experienced laser-scanning services is an option if you are considering purchasing scanning equipment for your company.

It is now possible to see any building digitally 3D in the digital age. Laser Scanning has seen great technological advances, including 3D Laser Scanning Surveying equipment and techniques that allow for faster processing of large amounts of data to provide more accurate representations of buildings and physical objects.

In essence, our brains collect huge amounts of visual and spatial data when we look at the world around us. This information is then processed by our brains into interpretive 3D images.

Laser Scanning Surveying follows the exact same processes but uses sophisticated machinery to collect the images, geometric and spatial data as well as a computer processor to process them.

The result is a large point in time 3D database that accurately depicts the environment scan. The “point cloud” laser scanning data is a geometrically stable and can be used. It also has many benefits for end users.

To obtain exact measurement information, ‘bombard’ the building, rail tunnel, road, or subject with millions upon millions of safe laser pulses. This is achieved by installing’state-of the-art’ equipment that emits these laser beam pulses, which are intended to bounce off the subject before being reflected back between two mirrors within the laser scanner.

This simple process provides very precise XY and Z coordinates for the object or surface that the laser points hit. Once the process is repeated many times, the co-ordinates are then processed by “3D cloud software” and exported to various 3D software such as revit, autocad or microstation. This allows for an exact 3D image of any building to be constructed.

It’s a high-tech method that can produce amazing results. It has applications in architecture and anywhere else where a digital representation might be useful.

There are more possibilities than your imagination can imagine! There are three areas in which laser scanning could be of benefit:

Accuracy- This process reduces the chance of human error which can often lead to complications during the construction phase. The laser scanner is not tired and does not make mistakes due to heavy work. It produces reliable results that are many times more accurate than other surveying methods.

Speed – 1,000,000 points per second allows for huge amounts of data to be collected quickly. The ability to obtain information in a matter of seconds allows for quicker decisions than traditional surveying techniques.

Laser scanning lets people focus on the things they love – This is the third benefit of laser scanning. People can now concentrate on the important aspects of a project instead of worrying about the numbers. As the end result improves, this almost invariably leads to better designs, happier, more productive employees, and happier clients.

There are many benefits to 3D Laser Scanning over other techniques. It is worth investigating if Laser Scanning Services would be a good fit in your business.

Since its inception in late 1990s, laser scanning’s application has expanded over time. Laser scanning is used in some industries, while others don’t. But, 3D scanning has a fundamental benefit for all scanning users: it allows them to gather precise spatial data that can be used to express their needs in different data formats.

It is possible that your company could use 3D scanning to capture spatial data. Here are four examples of areas where laser scanning has been beneficial.

Laser scanning (also known as laser surveying) was soon popularized in the engineering industry. This is because it allowed engineers to quickly incorporate design intent into computerized models. Also, engineers were able to troubleshoot products to find any deviations (warping and under trimming, over trimming etc.). It can be used to determine the intended product design. 3D scanning provides engineers with an improved method of reverse engineering products.

The laser scanners, just like engineering, revolutionized the industry of geographical surveying. In contrast to traditional surveying methods, which can take a lot of time and result in high surveying cost, construction companies or other entities that need land surveying can complete a project in one session. Laser scanning reduces the cost of the surveying process and the number of surveyors involved.

Laser surveying is not needed by law enforcement, as opposed to the engineering and geo surveying industries.

However, investigators of crime scenes and accidents often struggle to understand the exact cause and effect of an accident or crime without laser scanners. The laser surveying data allows investigators create crime scene animations and animations based on hard information.

The animations help to explain the circumstances of a crime, accident, and can be very persuasive to convince jurors in a trial.

The field of historical preservation does not seem to require laser scanning, much like law enforcement. Laser scanning’s ability to accurately measure objects of all sizes and collect spatial data makes it ideal for recording heritage objects data for restoration. The May 2010 scanning of Mount Rushmore’s monument was a recent example of preservationists using laser scanners.

Laser scanning (also known as laser surveying) was first introduced in 1998. It has quickly been associated with the engineering, manufacturing and construction industries. However, laser scanning has steadily grown in popularity, so that laser surveying can now be used by organizations such as police departments or archeological societies.

The recent surveying of Mount Rushmore monument in Mai 2010 is a good example of the way laser surveying technology has evolved over the past decade. Surveying experts scan the enormous sculpture to obtain its surface data. These data will be stored for restoration purposes in the event of sudden or gradual erosion.

The 3D laser scanning system that was used for this operation was shipped from Scotland. This is not unusual in today’s scanning culture. Surveying companies and suppliers offer their services regularly to cross-continental scanning project.

Because of the likely precipitation in Mount Rushmore, water-resistant scanning equipment was needed. Surveyors had to deal with fog, rain and snow as they gradually scanned the sculpture. Time-of-flight scanners that measure surface data at long distances from a laser rangefinder can have an impact on the project’s time and length. Triangulation scanners however have a greater scanning range, but better accuracy.

The Mount Rushmore statue was scanned by the surveying team. For restoration purposes, they also scanned the memorial site beneath it.

Whatever the scanning project, they all share the same goal: to capture exact physical data about an object, space, and environment. The advantages of 3D laser scanning over traditional surveying include a lower cost, faster results, greater accuracy, and easier storage than large amounts of 2D drawings. Many scanning providers offer 2D drawings for scanning data.

Despite the obvious advantages that laser surveying offers over traditional surveys, some companies still prefer to use the latter. Some also believe that scanning technology’s relative newness means that scan data will be more difficult to interpret for those not familiar with it.

In most cases, however, scanning companies deliver scan data already in the file types required by the customer. These include specific polygon mesh models and solid CAD model files, which can be edited and manipulated by the customer through a user-friendly interface. Some companies buy their own scanners. However, if you are on a budget, scanning services can be hired.

Laser scanning is also called laser surveying. This technology, which has a relatively short history and technical nomenclature makes it easy to misunderstand as only benefiting a few industries. Although 3D scans are mainly associated with the engineering and manufacturing sectors, they can be utilized by many other companies and organizations.

The laser scanner’s ability capture the exact physical data for objects, environments, and spaces is not only beneficial to companies that design or manufacture products, but also any company or organization that may need to collect the physical data. Below we will examine some of the areas that 3D scanning can be used to benefit entities not typically associated with laser surveying.

International police departments have started using laser scanners for crime scene evidence and accident site evidence capture. Laser scanners enable police to capture all the physical elements of an accident scene or crime scene regardless of its location. Some of these may be overlooked by investigators.

Along with allowing police officers to gather more information than they initially thought, laser scanners enable law enforcement to accurately determine bullet trajectory based the positioning of bullet hole. Additionally, police can create 3D animations based on scan data that allow them to recreate a crime scene or accident in real-time. These recreations are extremely valuable for both the prosecution and defense.

Archeological organisations use laser surveying in the same way that construction companies do: to survey the terrains and identify the best approach for excavation.

Laser scanning is also used by archeological groups to record the physical data of underground tunnels and chambers for archival purposes and restoration. Additionally, virtual tours are created for historical areas where public tours could be physically hazardous or threaten the integrity of the site.

Historical preservation societies use laser scanners for the collection of physical data on historical objects. They can then restore them to their original condition in the case of sudden or gradual damage. Additionally, scan data can be used to create smaller models of historical items for retail. Common examples include Michelangelo’s David, and the Eiffel tower.

The May 2010 scanning of Mount Rushmore’s monument and memorial park was a recent example of laser surveying being used for restoration. In the event of severe weather damage, or gradual erosion from the elements, the scans can be used to restore and reconstruct the monument.
