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 an orthomosaic.

A) Process the project:

1. Open the project rgb_dataset.p4d by double clicking on the file.
2. On the menu bar, click View > Processing. The Processing window opens at the bottom of the main window.

Note: As this project's goal is to generate an orthomosaic for an agricultural field, the Ag RGB template has been selected.

3. On the Processing window, 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 an orthomosaic for the whole project.

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 rgb_dataset.
5. (Optional) In Create In: Click on Browse, and on the Select Project Location pop-up window, 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 with the same name as 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) Activate 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 it is already set in the Image Properties window under section Image Coordinate System and does not need to be changed. The image geolocation is loadedThe camera model is loaded from the camera model database (Sequoia (RGB)).

11. Click Next.

The New Project wizard displays the Processing Options Template window.

Note: As this project's goal is to generate an orthomosaic for an agricultural field, the template to be selected is the Ag RGB template.

12. On the left of the window, select the Ag RGB template.
13. 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.

14. Under Unit, select m.
15. Select Auto Detected.
16. Select Advanced Coordinate Options and under Vertical Coordinate System select MSL egm96.
17. Click Finish to finish the wizard and create the project. The Processing window opens at the bottom of the main window.

B) Process the project:

1. On the menu bar, click Process > Processing Options... to open the Processing Options window.
2. On the Processing window, click Start to start the processing.

Once processing is finished, the Orthomosaic can be visualized and modified in the Mosaic Editor.
