Technology, as everyone says, is here to remove the extra burden of carrying out things manually. 3D technology, particularly 3D scanning services is lending a helpful hand in all the industries, whether it is healthcare, fashion, education, automobile, etc. The technology is empowering the working professionals to capture objects in the form of 3D files for printing and editing in the future. The 3D scanning industry has made great strides in the past few years and is slowly becoming a game-changing technology. Today, it has become a technological revolution which is worth exploring. Before heading towards the market to buy a scanner for your business or home use, it’s imperative to know the different types of scanners based on the technology used.
3D Scanning features available through 3D scanning services
1) Laser triangulation
The 3D scanning services which use laser triangulation scans the data using a single line of the laser. The scanner casts the laser light, which is reflected on the object. Finally, the trajectory of the light undergoes specific modification which helps the scanner to pick up data points. When the light undergoes modification along with some trigonometric triangulation, the scanner becomes capable of deciding the deviation angle. The angle is useful when capturing objects placed at a distance. Such scanners can scan the distant objects more accurately. These scanners are renowned for providing the highest possible accuracy and resolution. However, scanning shiny, glossy, and transparent objects still possess a challenge. Also, the laser triangulation scanners are an idea when the object is in motion as on a transfer line or a conveyor. Due to the high acquisition speed and low cost, these scanners are the first choice for many businesses.
2) Photogrammetry
As the name suggests, it is the science of making accurate measurements using photos. It uses digital pictures and certain geometrical algorithms to enhance the recovery of the exact surface point of the image, which helps in accurate measurement of the photos. The technology enables instantaneous capture of data, which is useful in capturing objects. Instant capture ensures that even though the object is in slight motion, it does not affect the process of data capturing. Furthermore, to get accurate measurements, you need a powerful computer to maintain the accuracy level of each photograph. Despite the shortcomings, the technology offers precision and high speed. Scanning using this technology might not be simple because it takes a lot of time to scan the photographs.
3) Structured light
Unlike laser triangulation, which uses trigonometric triangulation and modification to capture data, structured light scanners use only the trigonometric triangulation. A structured light scanner is capable of taking 3D images of what the camera can see. And, to create a digital model, scans are taken from different angles. The 3D scanning services using structured light scanners are an optimal solution when the target object is stationary. Businesses can even scan the human body using the structured light scanners.
When it comes to choosing the appropriate 3D scanning services, weigh your options, and understand the pros and cons of each before making a decision.
