1. What Is Photogrammetry?

Photogrammetry is the science and technology of obtaining reliable 3D information about physical objects and the environment by recording, measuring, and interpreting photographic images. In simple terms, it means turning 2D photos into 3D models.

It works by analyzing multiple overlapping images of a scene, identifying common points between them, and calculating spatial relationships using triangulation and camera geometry. The result is a digital reconstruction of the photographed object or landscape — including detailed textures, geometries, and elevation data.

This technique is widely used in industries like:

With the rise of UAVs (drones) and powerful desktop software like Metashape, photogrammetry is now affordable and accessible to professionals and researchers alike. Read also “How to Turn Drone Images into 3D Models with Agisoft Metashape”.

3. Recommended Hardware and Setup

Photogrammetry is resource-intensive, especially during dense cloud and mesh generation. For optimal performance with Metashape:

  • CPU: Intel i7/i9 or AMD Ryzen 7/9 with at least 6 cores (12 threads)
  • GPU: NVIDIA GPU with CUDA support – RTX 3070/4070 or higher is highly recommended
  • RAM: Minimum 32 GB, ideally 64 GB or more for large datasets
  • Storage: SSD for the system and processing folders (1 TB+)
  • Monitor: A large display (4K optional) helps during manual editing, especially for dense clouds and mesh refinement

If processing extremely large datasets, consider using network processing with multiple machines running Metashape Pro. GPU and RAM distribution can dramatically reduce total processing time.

4. Photo Capture: Tips and Best Practices

Good input equals good output. The quality of your photogrammetric reconstruction depends heavily on how the photos are taken. These best practices apply whether you’re using a drone, handheld camera, or tripod-mounted DSLR.

  • Image Overlap: Aim for at least 70–80% front overlap and 60–70% side overlap.
  • Consistent Lighting: Avoid shadows, overexposed skies, or highly reflective surfaces. Cloudy days are often best for terrain.
  • Fixed Focus: Use manual focus or lock autofocus to prevent shifting focus between shots.
  • Low ISO: Keep ISO low to reduce noise (ISO 100–200 recommended).
  • Shutter Speed: Fast shutter speed (1/800s or faster) avoids motion blur.
  • Camera Angle: For drone surveys, include nadir (straight down) and oblique (angled) images for better geometry capture.
  • EXIF Data: Preserve original metadata; Metashape uses this for geotagging and lens info.

When capturing small objects or indoor spaces, use a tripod and consistent distance. Ensure your lighting is even and avoid specular reflections. Read also “10 Pro Tips to Get Better 3D Models with Agisoft Metashape”.

5. Full Workflow in Metashape

This is a step-by-step outline of a typical photogrammetry workflow using Agisoft Metashape Professional. You can run each step manually or automate the process with Python scripting or batch processing.

Step 1: Add Photos

Drag and drop your images or use the menu: Workflow > Add Photos. If your project has multiple cameras or sessions, group images into chunks.

Step 2: Align Photos

Go to Workflow > Align Photos. Choose High or Medium quality, and enable adaptive camera model fitting. This generates a sparse cloud and calculates camera positions.

  • Accuracy: Higher accuracy improves camera alignment but increases processing time
  • Key Point Limit: Leave at default (40,000)
  • Tie Point Limit: Optional, lower for large datasets

Step 3: Import or Place Ground Control Points (Optional)

If working with survey-grade precision, import GCPs and mark them manually. Then reoptimize the camera alignment from the Tools > Optimize Cameras menu.

Step 4: Build Dense Cloud

Select Workflow > Build Dense Cloud. Choose quality (Medium or High recommended). The depth filtering option can be set to Aggressive to reduce noise or Mild for more detail retention.

Step 5: Build Mesh

Go to Workflow > Build Mesh. Choose data source: Dense Cloud or Depth Maps. Set face count based on output needs. For terrain, use the Height Field surface type; for objects, use Arbitrary.

Step 6: Build Texture (Optional)

Use Workflow > Build Texture to generate a high-quality texture map on your mesh model. Texture mapping is essential for visualization and 3D presentation, less so for geospatial outputs.

Step 7: Build DEM and Orthomosaic

To create topographic products, build a digital elevation model (DEM) and orthomosaic image from the dense cloud or mesh. You can also generate contour lines (e.g., 1 m intervals) for CAD/GIS workflows.

Step 8: Export Your Results

  • Point Cloud: LAS, LAZ, XYZ, PLY
  • DEM: GeoTIFF, IMG, XYZ
  • Orthomosaic: GeoTIFF, PNG, JPEG
  • Mesh: OBJ, FBX, 3D PDF, GLB, USDZ
  • Contours: DXF, SHP

Use File > Export for each data type. File naming and coordinate system consistency are important for GIS integration.

6. Optimizing Accuracy

While Metashape is capable of producing visually accurate models from basic photo sets, achieving survey-grade accuracy requires intentional setup and refinement throughout your workflow. Here are essential techniques to ensure high accuracy:

  • Use RTK/PPK-Enabled Drones: Geotagged images from RTK drones reduce the need for GCPs and improve alignment precision.
  • Ground Control Points (GCPs): For professional applications, use GCPs measured with GNSS to anchor your project to real-world coordinates. Mark GCPs in at least 3–5 images each.
  • Camera Calibration: Use a known calibration profile or enable camera model fitting in the alignment step. Avoid auto-focus during capture.
  • Reoptimize Cameras: After adding GCPs or markers, always run Tools > Optimize Cameras to reduce reprojection error.
  • Check RMS Error: In the Reference pane, check your GCP residuals. Aim for < 2 cm in X, Y, and Z for high-precision results.
  • Use Scale Bars: For object scanning without GPS, add scale bars to ensure metric scaling.

You can also reduce distortion and improve point cloud density by using fixed-lens cameras, avoiding wide-angle fisheye effects, and ensuring consistent focal length.

7. Common Mistakes and How to Fix Them

Even experienced users run into problems in photogrammetry. Here are the most common mistakes encountered in Metashape projects — and how to solve them.

📌 Misaligned Cameras

  • Problem: Some images fail to align, or alignment results look warped.
  • Cause: Insufficient overlap, featureless terrain, or motion blur.
  • Solution: Increase overlap, remove blurred images, or add markers manually. Try realignment with increased key/tie points.

📌 Soft or Incomplete Mesh

  • Problem: Final mesh lacks sharp features or has holes.
  • Cause: Poor dense cloud quality, shadows, or moving objects in photos.
  • Solution: Improve photo consistency, apply mild filtering, use depth maps as mesh source, fill gaps manually with mesh editing tools.

📌 Inaccurate DEM or Orthomosaic

  • Problem: Elevation surfaces are bumpy or contain artifacts.
  • Cause: Sparse or noisy dense cloud, poor camera positions.
  • Solution: Improve image set, reoptimize alignment, clean sparse/dense cloud before DEM generation.

📌 Crashes During Processing

  • Problem: Out-of-memory error or system crash during dense cloud or mesh build.
  • Cause: Large dataset exceeds system capacity.
  • Solution: Reduce quality setting, use chunk splitting, or enable tiled processing. Ensure enough free disk space and RAM.

Tip: Always save your project before intensive steps and enable auto-saving in Preferences.

 

8. Exporting and File Formats
