How Does 3D Scanning Technology Work?



How Does 3D Scanning Technology WorkIn the recent times, there has been a lot of discussions about the 3D technology. There are claims that the technology could have massive potential for job creation and wealth generation. However, some people are still in the dark as to how this technology works. This guide will give you an idea of how to utilize the technology. It is a technology that has the potential to revolutionize the world of all fields.

What is a 3D Scanner?

Many devices qualify to be called 3D scanners. It is a device that utilizes lights, X-rays or lasers to take measurements of physical objects. By using light, X-ray, or lasers, these devices can create polygon meshes or dense point clouds. The common point of these devices is that they can map out the physical dimensions of any object with accuracy.

How Do 3D Scanners Work?


How Does 3D Scanning Technology WorkAlthough there are many approaches in 3D scanning, all of them rely on the principles of imaging. Some scanners are good for taking scans at short ranges while some are ideal for mid to long ranges. Short range scanners have a limit of one meter.

The Process of 3D Scanning

The first step in taking a 3D scan of an image is to place it on a bed from where it is scanned. It is usually the case for short range scanning when using a laser scanner. In this process, specialized software is used to control a laser emitting gadget over the surface of an object. The device will project a laser onto the object with two cameras in tow. These cameras make a recording of the changing length of the laser beam. It is done along the three axes of XYZ.

People who are working on the project also take this time to correct any imperfections on the 3D scan. However, there may be no need to do this especially if the machine has a high degree of accuracy.

For longer ranges, a different type of scanner is used. It is based on the fact that we know the speed of light with high precision. Instead of cameras, lasers sensors are used. As the laser pulses back and forth, these sensors calculate how long the beam takes to get back to the device. With this type of scanner, it is possible to take a full 360-degree scan of an object. However, all the electronics have to be calibrated with extreme accuracy. It helps to ensure accurate results can be got.

The Uses of 3D Scanning

3D scanning is an excellent technology for conducting inspections. It helps researchers to identify anomalies that the human eye may miss. As a result, they are an awesome way to make corrections to devices that require a high degree of accuracy.


3D scanning is an important technology that continues to transform lives. It is just a basic guide, and there is still a lot more that can be learned about the technology. In addition, it might be a lucrative career path to follow.
