The downloaded folder contains the following files and folders:
*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.
This section describes how to process the dataset using the included .p4d project file in order to generate a 3D mesh of a house.
1. Open the project example_dji_house.p4d.
|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 Pix4Dmapper.
6. (optional) Select the check box Use As Default Project Location to save all new projects in the selected folder.
The New Project wizard displays the Select Images window.
9. Click Add Directories... and select the images folder to add to the project.
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 Auto Detected.
The New Project wizard displays the Processing Options Template window.
15. Click 3D Models to select the template.
Note: As the goal of this project is to generate the 3D model (no DSM and Orthomosaic), the template to be selected is the 3D Models template.
16. Click Finish to finish the wizard and create the project. The Processing window opens at the bottom of the main window.
1. On the Processing bar, select 1. Initial Processing and deselect 2. Point Cloud and Mesh.
When Initial Processing finishes, the rayCloud opens. Points from the sky and background are reconstructed.
C) Improving the results using a Processing Area
For this project, a Processing Area can be used. A Processing Area can be used to remove noisy points from the background and sky. For more information about how to draw a Processing Area with the rayCloud: 202560179.
D) (Optional) Point Cloud Editing
If the Processing Area does not remove all noisy points, they can be removed by manually editing the point cloud. For more information about how to manually edit the point cloud in the rayCloud: 202560499.
E) Generate the 3D Textured Mesh
On the Menu bar, click Process > Generate 3D Textured Mesh to regenerate the 3D Textured Mesh.
