3D-Reconstruction & 3D-Scanning<\/strong><\/p>\n

<\/p>\n

An increasing part of my work is working with different scan data. Be it so-called photogrammetries for visual purposes (games, movies, gamification). Or high-precision laser scans for industrial purposes or 3D visualization, here the decisive keyword would be the digital twin.<\/p>\n

<\/p>\n

In the end, however all scans in common that they consist of triangles and we 3D artists can create wonderful things from exactly these cute sweet little vertices.<\/p>\n

<\/p>\n

I have prepared a small example here which tries to visualize the topic of 3D-Reconstruction & 3D-Scan.<\/p>\n

<\/p>\n

3D reconstruction<\/strong> refers to the process of creating a three-dimensional representation of an object or scene. This can be done through a variety of methods, including 3D scanning, photogrammetry, or structured light scanning.<\/p>\n

In 3D scanning<\/strong>, a physical object is scanned using a 3D scanner to create a digital model of the object’s surface. This can be useful in a variety of applications, including manufacturing, product design, and archaeology. 3D scanning can also be used to create virtual models of objects that are too fragile or valuable to handle, or too large to transport.<\/p>\n

Photogrammetry<\/strong>, on the other hand, involves taking multiple photographs of an object or scene from different angles and using software to create a 3D model based on the images. This technique is often used in surveying, architecture, and cinematography.<\/p>\n

Structured light scanning<\/strong> involves projecting a pattern of light onto an object and measuring the distortion of the pattern as it reflects off the surface. This allows for the creation of a highly detailed 3D model of the object’s surface.<\/p>\n

Once a 3D model has been created through any of these methods, it can be used in a variety of applications, such as virtual reality, video games, product design, and even medical imaging.<\/p>\n

Overall, 3D reconstruction is an important field with a wide range of applications, and it is constantly evolving with advances in technology and software.<\/p>\n

The Scan Process<\/strong><\/p>\n

<\/p>\n

To do the First Step, the ice cream cone was sprayed with a special spray powder to prevent the infrared light from penetrating the Scan-Item and to get a Scan with a clean surface. if possible without any noise!<\/p>\n

<\/p>\n

\"\"<\/a><\/p>\n

<\/p>\n

By spaying the article, a clean scan is possible and is now exported accordingly tessellated. (RAW-LaserScan).<\/p>\n
