Instructions

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 a 3D textured mesh of the building using Parrot Bebop 2.

1. Open the project example_bebop2_industrial_building.p4d.
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 the 3D textured mesh (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 processing.

Process the dataset creating a new project

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

A) Create a new project:

1. Start Pix4D Desktop.
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_bebop2_industrial_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 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) 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. The folder contains the images of the grid mission and circular flight. Click Choose.
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 (Bebop2_1.8_4096x3320 (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. Select Known Coordinate System and Advanced Coordinate Options. Click From List... button, select World Geodetic System 1984 datum and  WGS 84 / UTM zone 30N coordinate system, click OK.
13. Under Vertical Coordinate System select MSL. Set the value to egm96.
14. Click Next.

The New Project wizard displays the Processing Options Template window.

15. Click 3D Models to select the template. Click Finish to finish the wizard. The Processing bar opens at the bottom of the main window.

B) Process the project:

16. On the Processing bar select 1. Initial Processing and deselect 2. Point Cloud and Mesh.
17. On the Processing bar, click Start to start processing.

 
Note: Pix4Dmapper automatically detects the sky in the images of Bebop2 and improves the Densified Point Cloud.

When Initial Processing finishes, the rayCloud opens.

18. Use the rayCloud to define a Processing Area to remove noisy points from the background and to keep only points of the building. For more information about how to draw a Processing Area with the rayCloud: 202560179.

 
Note: The Processing Area used:

19. Edit the Processing Area to focus on the area of interest. For more information about how to edit a Processing Area with the rayCloud: 202560599.

 
Note: In the above Processing Area, the Maximum and Minimum Altitude are set to 50.00 [m] and -10.00 [m] respectively.

20. On the Processing bar, deselect 1. Initial Processing, and select 2. Point Cloud and Mesh.
21. On the Processing bar, click Start to start processing.
