3D scan for CGI – is this possible?

We report on this from one of our numerous projects. One of our customers wanted to digitize their entire tableware range, consisting of several hundred individual pieces, to create cross-marketing 3D models. In this case, the 3D models should be used for CGI (computer generated image). The client decided to call on our support for this project as no 3D data was available for the objects. Due to the total volume and the extremely high effort involved, this was a challenge for everyone involved.

The aim was to generate clean, detailed and true-to-scale 3D models (geometry) as well as high-resolution and true-color textures in 8K for the CGI product images from scanned data. Due to the different sizes, shapes, colors and levels of detail (even within) the different series, this was a major challenge. In consultation with the customer, we decided to use structured light scanning technology in combination with photogrammetrically generated textures. This approach has several advantages. On the one hand, this enabled us to capture the exact shape of the objects and, on the other, to create high-resolution textures.

It then became difficult to correct scan, light and lighting errors that occurred due to the shape of an object and to process them in such a way that every product in a series is 100% identical and correct in terms of color. Our experienced 3D artists have combined various workflows from our portfolio to achieve the best possible results. A benchmark was set by the customer for each series, so that consistent results could be guaranteed.
