Photogrammetry — turning hundreds or thousands of photos into a detailed 3D model — is a quietly demanding, margin-rich niche serving surveying, heritage documentation, film assets, and increasingly drone-based mapping in Nigeria. Software like RealityCapture and Metashape will use every scrap of hardware you give it: it's CPU-heavy during alignment, GPU-accelerated for depth and meshing, RAM-hungry on large datasets, and storage-intensive throughout. There's no single bottleneck to optimise — it punishes any weak link.
This guide covers building a photogrammetry and 3D-scanning PC in Nigeria, where the answer is a balanced, capable workstation rather than a one-spec hero. It connects to our 3D-artist workstation guide.
Why Photogrammetry Needs Balance
The photogrammetry pipeline stresses different components at different stages:
- Alignment (matching photos): heavily CPU-bound — core count and speed both help.
- Depth maps & meshing: GPU-accelerated in modern software — a capable GPU with good VRAM speeds this dramatically.
- Large datasets: thousands of high-res images and dense point clouds are extremely RAM-hungry — this is where many builds choke.
- Throughout: reading and writing large files demands fast, generous NVMe storage.
Starve any one of these and the whole process crawls or fails — so you build broad, not narrow.
Where Your Naira Should Go
- Plenty of RAM, first for large datasets — 64GB is a sensible serious baseline; big projects want more. This is the most common bottleneck.
- A strong multi-core CPU — alignment rewards cores and clock speed.
- A capable GPU with good VRAM — accelerates depth and meshing stages.
- Fast, large NVMe storage — datasets and outputs are huge.
Our Recommended Photogrammetry Build (2026)
- CPU: Ryzen 9 (high core count) — alignment is CPU-bound
- GPU: a capable RTX 50-series card with solid VRAM for depth-map and mesh acceleration
- RAM: 64GB DDR5 (128GB for large drone-mapping datasets)
- Storage: large fast NVMe for working datasets + capacity for archives
This is genuine workstation territory — see our ₦3M and ₦5M guides for where it lands depending on dataset scale.
Drone Mapping Pushes It Further
If your work includes drone-based aerial mapping, expect dataset sizes to balloon — large surveys can mean thousands of high-resolution images and enormous point clouds. That pushes RAM and storage requirements up sharply, and makes the case for the higher end of the spec. Size the build to your largest realistic project, not your smallest, because the big datasets are where weak hardware fails.
The Nigeria Tax
Photogrammetry processing runs long and hard — protect it on clean power so a multi-hour alignment isn't lost to an outage, and keep the machine cool to sustain performance. Plan serious storage and backup, since datasets and finished models accumulate fast and represent real fieldwork you can't easily recapture.
Frequently Asked Questions
What's the bottleneck in photogrammetry? There isn't a single one — alignment is CPU-bound, meshing is GPU-accelerated, large datasets are RAM-hungry, and the whole pipeline is storage-intensive. You need a balanced build, not one hero component.
How much RAM do I need for photogrammetry? 64GB is a sensible serious baseline; large drone-mapping datasets can want 128GB or more. RAM is the most common bottleneck on big projects.
Does the GPU matter for RealityCapture and Metashape? Yes — modern photogrammetry software uses the GPU to accelerate depth-map generation and meshing, so a capable card with good VRAM speeds those stages significantly.
Why does drone mapping need more? Aerial surveys produce thousands of high-resolution images and massive point clouds, sharply increasing RAM and storage needs. Size the build to your largest realistic dataset.
The One Thing to Remember
Photogrammetry rewards balance, not a single big spec — give it plenty of RAM for large datasets, a strong multi-core CPU for alignment, a capable GPU for meshing, and fast, generous storage throughout. Size it to your biggest realistic project (especially with drone mapping), and protect the long processing runs with clean power. Build broad and no stage of the pipeline becomes the wall.
