Adding Enhanced Texture To 3D Scans With Photogrammetry
How our photo texturing service can take your 3D models to the next level with enhanced photorealistic textures
Are you looking for enhanced realism in your 3D scan textures? Our photo texturing service gives 3D models the same crisp texture as a photogrammetry model, with the highly accurate mesh body of a 3D scan!
Photogrammetry VS 3D Scanning
Photogrammetry will create a model with a more realistic texture, but a less accurate mesh than a 3D scan. This might mean that the model looks highly detailed with the texture on, but once the texture is removed, fine detail is lost and the mesh itself looks less defined. Conversely, 3D scanning will provide a highly detailed mesh (down to 0.5mm accuracy), but a more dull texture than photogrammetry overall.
Our photo texturing service combines the best of both worlds, by creating a mesh based on 3D scanning and aligning it with a texture created by photogrammetry.
A Look Into The Photo Texturing Process
We start our photo texturing process by getting a scan of our subject on a textured background. The background provides important tracking data to our software that will help it match the subject's position in our scan to the subject's position in the photos. This is important for proper texture alignment.
Before flipping our subject over to scan the other side, we move it into our photo booth. It's important to be careful with this step as any movement of our subject on the textured background could result in a misaligned texture.
When taking photos it's important to make sure the lighting is consistent and not too harsh. Changes in lighting can cause the final texture to look patchy and unusually colored, while harsh lighting can create a glare effect.
We take about 20 photos and then move our subject back to the scanning table to scan the underside.
We repeat this process of scanning and taking photos until all sides of the subject are captured. The software we use gathers data from both the scans and photos and aligns them together to create our final model! It's important to note that the mesh itself is only constructed from scan data, while the texture is made from our photo data. The final result is a highly accurate mesh with a crisp, photorealistic texture!
Photo Reference Service
While on the topic of cameras, we also offer a photo referencing service that provides you with in-depth photos of your scanning subject to use as a reference for any further custom texturing or modeling you'd like to do on your own.
Standard Photo References - Photos of your scanning subject from six different angles (Top, Bottom, Front, Back, Left Side, Right Side).
Macro Photo References - We can use a macro lens to capture highly detailed, close-ups of scanning subjects. These work great as a reference for how texture appears in smaller areas, such as areas with fine stitching and fabric details.
Polarization Lens - We can use this with any photo service to reduce glare around the edges of more reflective scanning subjects.
