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.
