The digitization of physical objects and spaces is becoming increasingly important — particularly in the context of the shift from the classic 2D web to immersive 3D applications. Whether for virtual exhibitions, digital twins or augmented reality: There is an increasing need to transfer real environments and objects precisely into the digital world.
There are currently three different approaches available, which differ not only in cost and effort, but above all in their accuracy and physical authenticity. During traditional scanning methods While delivering high-quality results, they are time and cost intensive, offer AI-based methods Although a quick alternative, physical correctness is often omitted. Radiance Fields process On the other hand, they combine the advantages of both worlds: They enable high-precision, photorealistic 3D reconstructions with minimal effort — and thus form the basis for economic and scalable digitization.
The three solutions are compared below. :
1. Traditional scanning/modelling methods
- Manual creation or scanning (laser scanner/photogrammetry) including manual post-processing
- Disadvantages: High time and cost, expensive hardware, specialist knowledge required
- Result: High-quality but economical only for special cases
2. AI-based generation
- Use generative algorithms (often diffusion)
- Create synthetic reconstructions — “interpret an image instead of calculating the 3D model”
- Result: More cost-effective than traditional processes, but not physically authentic 3D models
3. Radiance Fields process
- Mathematical method with physical validity - no interpretation
- Reconstructs real geometry through point cloud transformation
- Delivers photorealistic and 100% authentic models at the lowest cost
With Obsphera, we offer a SaaS solution for companies that creates high-quality photorealistic 3D reconstructions directly from photos and videos. The combination of the latest Radiance Fields technology Gaussian Splattin, g supplemented by machine learning and AI in upstream and downstream processes, is ideal for achieving the best possible quality at the lowest cost with 100% authenticity.
