Applications Of Structured Light 3D Scanning Technology

One of the greatest technological invention (besides the wheel and the like, of course) is the creation or 3D scanning techniques. The creation of a 3D model of anything is phenomenal in a number of important applications. There are a number of 3D scanning technologies, one of which is structured light scanning. Simply put, this is a non- contact technology used for both reverse and inspection engineering. Essentially, structured light scanners employ projected cameras and light to take 3D measurements of an object.

Structured light scanning technology has been around for thousands of years. Mathematicians from Babylon and Egypt began using the technology as far back as 5,000 years ago. However, it wasn’t until the end of the 19th century that the first-ever advanced cameras were introduced to the market. Over the years, the cameras have been infused with modern technology and now make for versatile manufacturing and research tools. Without further ado, here is a quick outline of what structured light 3D scanning is and who uses it.

How does 3D structured light scanning work?

Although there are various principles behind structured light scanning, the concept revolves around triangulation. This is where a light is transmitted in a specific pattern that distorts itself on the surface of the target. Multiple cameras capture the distortion at different angles and the distance between certain points on the target is calculated using triangulation. The 3D coordinated are then utilized to create a detailed digital reconstruction of the object.

Both white and blue lights are used in a structured light scanner. Although both have impressive speeds and precision, blue light seems to be the ideal option for many. This is because it has a long-lasting LED light source, a more potable gear, a lower temperature compared to white light and a high scanning tolerance.

Applications of structured light scanning

For the most part, non-contact 3D scanning finds use in situations where creating a digital object with a contact scanner is virtually impossible. These include the recreation of a delicate, difficult to grip, and elastic objects. The real reason blue light structured light scanners are popular is because they deliver an impressive efficiency gain. As a result, the scanners are useful in a number of industrial applications such as reverse engineering, 3D modeling, scientific measurement, and computer-aided inspection.

Parting Thoughts

As you can see, a structured light scanner is highly beneficial in today’s world. It allows for easy and fast recreation of objects of all shapes and sizes. It is thus an invaluable tool for a number of industrial and manufacturing applications.

Choosing The Best Structured Light Scanner

3D animation is a digital animation technique equivalent to volume animation in a virtual world. 3D animations are complex artistic works on which the mastery of multiple processes depends.

The illusion is shaped around the creation of a universe and characters both surprising and an almost palpable reality. Behind the power of computers and software, the tremendous human genius has given access to a dream: to give life to a rather abstract technological material at the outset, and to set up stories without limitation for the imagination. This is why limiting the Universe of 3D to a simplistic vision would be a mistake.

A 3D modeling software originally developed by the company Not A Number Technologies and now offered to the graphic design community. This software is a complete suite allowing to realize images and animations of synthesis. Its interface, stable and modern, includes modeling tools (bezels, b-spline), animation and rendering (scanline type, shadow-map shading, layer and particle system, panoramic rendering). possible field) of high quality thanks to the the Best Structured Light Scanner.

It is able to animate everything, from textures to meshes, through the lamps and their parameters. Like any good 3D software, It is able to save all your work in a single file, and gives you the ability to access it as libraries. In addition, it can import and export other types of files (import/export DXF, import/export AVI and AVI RAW). Despite its initial approaches, It attracts more and more

In most cases, objects and characters are constructed in three-dimensional models (volumes are defined with a surface texture), and computer algorithms treat these models to generate the image by simulating incident light (effect of sun, a lamp) and treating different effects (including shadows and reflections).

Volumes, landscapes, characters, everything is built from polygons. A good 3D modeler can from a simple cube build surprisingly complex shapes. He then works the colorimetry, and of course the lighting is not done automatically, it is a question of placing it at best for a plausible rendering, or effects on the volumes and the general mood of the scene.

The Best Structured Light Scanner generates images having the aspect of a cartoon contrary to the generally photorealistic aspect of the image synthesis. Since making a cartoon requires the completion of many individual drawings, it may be faster to create the animation in 3D and let the computer calculate the many images.

Motion capture involves placing sensors on the body of one or more actors, such as joints. Each sensor sends its coordinates through infrared cameras. The emitted signal is sent to a powerful computer. When the actor plays, the positions of the sensors are recorded in three dimensions. This data can then be inserted into a professional computer-generated image creation software.

4 Simple Tips To Boost 3D Laser Scanning Results

In the world of reality capture, getting a flawless image of your subject is vital to most projects. However, due to the challenges that come with Laser Scanner technology, achieving this result can be challenging. There are ways to overcome said challenges and the following are 4 simple tips you need to apply to boost your scan results.

1. Use Multiple Angles

To get a detailed digital 3D image on a physical object, you will require either investing on a spin table or taking multiple scans from different angles. Depending on your budget, you can consider using a motorized rotary table or a manual turntable. This will allow the scanner to capture all the details of the subject. If this isn’t an option, then taking multiple scans from different angles of the subject is vital. Once this is complete, compile all your different images to get your desired result.

2. Explore the Site

This is recommended for field scans. If you are going to scan large areas like oil plant or a building, you will need to tour the facility and familiarize yourself with it. This will give you an idea of the precautions to take during the scan process. On the other hand, if your subject is small, it is your job to control your environment. These precautions will go a long way into ensuring that the final scan result is top quality.

3. Higher Speed over Higher Resolution

Higher scan resolution will use lower speeds, while low resolution will use high scan speed. Movement disrupts scanning and produces poor results. In a subject whose body is made for movement, the scan needs to be completed in the quickest time possible. Choosing higher scan speed with low resolution will get the scan completed quicker hence reducing the chance of movement and producing a quality scan.

4. Back Up All Data

In a world where digital data is lost all the time, it is wise to protect your work from this misfortune. After every scan, store the data in a separate device so that you can compile it later when you are ready to work on the final scan. With all your raw data stored away, you have all you need to create your final quality product.


Due to the sensitivity of laser scanners, taking a quality scan requires precision and preparation. The above simple tips will go a long way into ensuring that your scanning process is a smooth one. Preparing the site beforehand, reducing the scan speed, collecting enough scans, and backing them up are simple ways to ensure that your end result is high quality.
