What is photogrammetry?
Photogrammetry is a scientific and technical discipline that enables the collection of precise 3D information about objects and terrain through photo analysis. Essentially, it’s a digital extension of human stereoscopic vision: just as our brain combines two flat images from our eyes to perceive depth, software analyzes hundreds of images from different angles to reconstruct a 3D object.
Drone scanning enables fast and safe capture of high-quality images of even the most inaccessible parts of architecture—church towers, complex roofs, or ornate details at great heights. These photographs are processed by specialized software that detects common points between images. This process creates a dense point cloud, then a geometric mesh, and finally a photorealistic texture is applied. The result is a highly accurate 3D model with faithful reproduction of shape, texture, and color.
To achieve millimeter-level precision, photogrammetry is often supported by LiDAR (Light Detection and Ranging) technology. LiDAR sends laser pulses and directly measures the distance to surfaces, creating a highly accurate skeletal framework, while photogrammetry provides the photorealistic “skin.”
Photogrammetry vs LiDAR – Comparison
| Criteria | Photogrammetry | LiDAR |
|---|---|---|
| Data acquisition method | Analysis of hundreds of 2D photos | Direct laser-based distance measurements |
| Main advantage | Photorealistic texture and color | Millimeter-level geometric accuracy |
| Limitations | Susceptible to lighting and reflective surfaces | Less realistic appearance without photographic data |
| Best suited for | Documenting details, frescoes, richly textured surfaces | Engineering surveys, inventory of large complex structures |
In practice: combining both methods yields a model that is both precise and photorealistic.
What can photogrammetry achieve?
Creating a digital 3D model is just the beginning. The true value of this technology lies in its versatile applications that are transforming the way we protect, study, and promote cultural heritage.
- Precise inventory and digital archiving of heritage
Photogrammetry provides an objective, non-invasive, and long-term record of an object’s condition at a given point in time. Photo resolution (GSD) down to 0.12 cm/px allows architects and engineers to plan conservation, monitor cracks or deformations, and generate sections or orthographic projections.
- Education, promotion, and virtual tourism
Interactive 3D models can be embedded on websites, providing immersive experiences to audiences worldwide. In education, students can engage with artifacts and better understand complex structures. For cities, interactive heritage models become a powerful promotional tool.
- Virtual reconstruction and analysis
Based on 3D models and historical data, it is possible to reconstruct destroyed or lost fragments of buildings, visualizing their original form and supporting academic research.
- Online 3D model presentation
Specialized model-hosting platforms allow users to rotate, zoom, explore cross-sections, or view objects in VR/AR—turning passive viewing into active exploration.
- Virtual presentations and 3D holograms
Models can be showcased in interactive web presentations or as 3D holograms visible in open space—without VR glasses. Perfect for exhibitions, fairs, and business presentations.
Our mission: protecting and promoting Polish heritage
Atlas 3D specializes in the digital documentation of national heritage—from churches to castles. Our surveys meet strict accuracy requirements (GSD 0.12 cm/px) and are 100% non-invasive. Ultimately, we aim to build the Atlas 3D—a living digital library of Poland’s architectural treasures.
From digital models to physical objects: realistic scale models
The bridge between the digital and physical world is the creation of precise 3D scale models. Benefits include:
- Unmatched precision: Reproduction of the finest architectural details.
- Any scale: From small desktop models to large museum centerpieces.
- Speed and efficiency: A complex model can be created within hours.
This is how our models are made at BRAWAGO
