Download* and project files

The dataset can be downloaded here.

The project can be found processed on Pix4D Cloud here

The downloaded folder contains the following files and folders: 

  • images: RGB images in JPG format.
  • example_building.p4d: project file that can be opened in Pix4Dmapper.

*The usage of this dataset is meant to be for personal and professional training. If you would like to use it for commercial or promotional objectives, please be sure to mention "Courtesy of Pix4D / pix4d.com" linking all this text to pix4d.com.


Follow the instructions to:

Process the dataset using the included .p4d project file

This section describes how to process the dataset in order to generate the 3D model of a building.

1. Open the project example_building.p4d by double clicking it. 
2. On the Menu bar, click View > Processing. The Processing bar opens at the bottom of the main window.

Note: As the goal of this project is to generate only the 3D model (no DSM and orthomosaic), the template used for the processing has been set to 3D Models. This can be seen in Process > Processing Options... .

 3. On the Processing bar, click Start to start the processing.

Process the dataset creating a new project

This section describes how to create and process a project in order to generate a 3D model of a building.

A) Create a new project:

1. Start Pix4Dmapper.
2. On the Menu bar, click Project > New Project....
3. The New Project wizard opens.
4. In Name: Type a name for the project. In this example type example_building.
5. (optional) In Create In: click Browse..., and in the Select Project Location pop-up, navigate to select the folder where the project and results will be stored and click Select Folder.

Note: When the project is created, a folder named after the project name typed in the Name field will be created in the selected folder and will store all the results. The .p4d project file will also be stored in this folder.

6. (optional) Select the check box Use As Default Project Location to save all new projects in the selected folder.
7. In the section Project Type, keep selected the default option New Project.
8. Click Next.

The New Project wizard displays the Select Images window.

9. Click Add Directories... and select the images folder to add the images to the project.
10. Click Next.

The New Project wizard displays the Image Properties window. The image geolocation is automatically loaded from the image EXIF data and is given in WGS84 (latitude, longitude, altitude) coordinates with vertical coordinate system given by MSL egm96. The camera model is loaded from the camera model database (NEX-5_E16mmF2.8_16.0_4592x3056 (RGB)).

11.Click Next.

The New Project wizard displays the Select Output Coordinate System window. By default the last output coordinate system selected in the software is selected.

12. Under Unit, select m
13. Select Auto Detected.
14. Select Advanced Coordinate Options and under Vertical Coordinate System select MSL > egm96.

The New Project wizard displays the Processing Options Template window. 

Note: As the goal of this project is to generate only the 3D model (no DSM and orthomosaic), and as it has been taken using terrestrial images, the template to be select is the 3D Models template.

15. Select the 3D Models template.
16. Click Finish to finish the wizard and create the project. The Processing bar opens at the bottom of the main window.

B) Process the project:

1. On the Processing bar, click Start to start the processing.
