Getting Started with 3Dsurvey

Importing Images with EXIF/GPS Orientation

Welcome to 3Dsurvey tutorials.

This tutorial shows how to start your project and demonstrates the workflow from importing images and EXIF data to generating a point cloud and calculating an orthophoto.

This scenario applies if you’re using images captured by drones, such as Inspire 1, eBee, Falcon 8, or any other UAV that records GPS data (cca. 1.5m accuracy) and saves it as part of EXIF inside your image file (typically jpeg).

1. Importing Images and EXIF Data

Open 3Dsurvey, navigate to Images -> Load images, and select your project folder. When the Telemetry Importer window appears, select EXIF data and import.

2. Bundle Adjustment

Run the Bundle adjustment feature and set parameters like global alignment and flight height. Confirm or adjust camera parameters such as focal length.

3. Reconstruction Process

Click Reconstruction to generate a dense point cloud. Set reconstruction parameters, then allow time for processing.

4. Point Cloud Classification

Open the Classification tool, select terrain areas, and let 3Dsurvey classify points for a clean model.

5. Digital Surface Model (DSM) Calculation

To create a DSM, navigate to DSM -> Calculate new, set grid size, hole fill interpolation, and smoothing settings.

6. Orthophoto Generation

Finally, go to DOF -> Calculate new, confirm parameters, and generate a digital orthophoto with accurate colors and survey-grade detail.

Conclusion

Your orthophoto is ready! For further steps, explore tutorials on 3D measurements, volume calculations, contour line generation, and more.
