Details About 3D Scanner

3d scanner is the future. You can do a lot of things with 3d scanner that is impossible to do without this. 

But what is a 3d scanner and what is the history of it? What types of 3d scanners are available? Or what are the uses of it? 

Well, you should know all these options to enrich your knowledge and get the benefits from it. So, let’s dive into the main part. 

What is a 3D Scanner

3D scanning is a process of recreating a real physical object’s ins and outs to a virtual 3D medium. For correctly analyzing the physical parameters, appearance, shape, and color of an object a 3D scanner is used. Texel can help you learn more about the different concepts of a 3D scanner. 

The 3D scanner can be a single device or a combination of devices that can represent a real-time object into a three-dimensional model digitally.  3D scanners do the compiling of 2D images in such a way that the 3D model becomes alive inside the screen. 

3D Scanning History

In 1960, the first 3D scanning procedure was experimentally and it was a success. The process was very lengthy and expensive. They used multiple 2D cameras, lights, and projectors to take a lot of images of an object. Then the compilation of the raw images was done manually using a computer. Therefore, there remain a lot of errors.  

Besides, the results back then were not accurate and enhanced as of today’s one. Afterward, EMR’s, optical technology, and innovations were developed for better performance. Collaborating with high-speed computers with statistical analyzing software resulted in more enhanced 3D scanning

Types of 3D scanners

Laser Oriented 3D Technology

Most advanced 3D scanners use LASER to accurately measure the physical dimensions of an object. The depth of the object is calculated by shooting and receiving a laser from the source to the target. By further receiving the laser the accurate measurements of the parameters are calculated. 

Light Projection 3D Scanners

These scanners can shoot a structured beam of Blue and White towards the object. The deflected light due to the object’s shape creates a vacancy in the light structure. By further studying the incoming structure of light, the 3D scanner compiles the result and outputs a 3D image.

Photogrammetry 3D Scanner

It is the most common and wildly used 3D scanning process by personal users. It is a simple process of combining a lot of raw images of an object. 

In this process, many photos of the subject are taken by high-resolution cameras from different angles.  The photos are then processed to compiled using computer software to get the digitalized 3D version of the object. 

The focal length, depth, and size of the images are used to arrange them linearly together. For this, a quality camera with high DPI and resolution should be used.

Where To Buy a 3D Scanner

Portable projection-based 3D scanners can be bought from physical shops or verified online marketplaces. Some models of laser-oriented 3D scanners can also be bought from global or local online marketplaces. 

Industrial grade 3D scanners are very expensive and not available for purchase by regular buyers. 3D scanner production-based companies sell them to only licensed heavy industries or companies. These cannot be bought at once. Companies need to preorder for it which needs required customizations by the buyers. 

Photogrammetry-based 3d scanning requires any casual cameras or even smartphones. Some paid image compiling software turns the raw images into a virtual 3D image.
