Processing projects - PIX4Dcatch

Follow

After a PIX4Dcatch project is captured, it can be processed as a 3D model using several options: directly uploading and processing to PIX4Dcloud / PIX4Dcloud Advanced for the most immediate results, or exporting the project and processing locally using PIX4Dmatic or PIX4Dmapper.

Upload to PIX4Dcloud / PIX4Dcloud Advanced

For fast results, uploading and processing to PIX4Dcloud / PIX4Dcloud Advanced can be done at the simple click of a button and provide quick shareable 3D reconstructions.

 
Important: A PIX4Dcloud or PIX4Dcloud Advanced license is required to upload the project for cloud processing. For more information, please check our offers.
 
Tip: If a PIX4Dcatch project has at least three marked Tags or GCPs, cloud processing will consider them automatically to improve accuracy. For more information: How to use Automatic Tag Detection and Manual GCP Marking - PIX4Dcatch RTK

Upload from the Project View

It is possible to upload directly to PIX4Dcloud / PIX4Dcloud Advanced for processing after capturing the project. In the project view, do the following:

  1. At the top of the screen, tap the blue Upload button upload button.
  2. To select the project processing options, please click here.
  3. After all images are uploaded and processing begins, a first email notification is sent.
  4. After the processing is finished, a second email notification is sent.
  5. The processed results can be viewed directly in the app and shared on PIX4Dcloud.

Upload from the Project Dashboard

It is also possible to upload directly to PIX4Dcloud / PIX4Dcloud Advanced from the project dashboard. The project dashboard lists all of the projects taken on the mobile device.

  1. Tap the folder icon project folder icon to access the project dashboard.
  2. Tap and hold on the desired project to access the menu.
  3. Tap Upload. PIX4Dcatch upload cloud icon
  4. To select the project processing options, please click here.
  5. After all images are uploaded and processing begins, a first email notification is sent.
  6. After the processing is finished, a second email notification is sent.
  7. The processed results can be viewed directly in the app and shared on PIX4Dcloud.

Upload Processing Options

After tapping Upload, the Upload Dataset window appears providing further processing options: Account and Organization, Project Cost and Account Balance, Cloud Processing Options. Each option is described in the table below.

Processing Options

Description

New Dataset | Site The captured project can be uploaded as a New Dataset or it can be assigned to an existing Site if a PIX4Dcloud Advanced license is available. To select a site, switch to the tab Assign to. For more information, please refer to Drive - Pix4DCloud.
Account and Organization If you are a member of more than one organization, you can upload the dataset to a specific organization and use their credits, as well as assign the dataset to one of the sites belonging to that organization. For more information, please refer to Organization Support.
Project Cost and Account Balance New users who upload a captured project directly from the app get a free PIX4Dcloud Advanced trial license with 40 credits that can be used for processing. For more information about the credit system, please refer to PIX4Dcloud / PIX4Dcloud Advanced credit balance system.
Cloud Processing Options
  1. Measure Volumes and Elevation Profiles: Select the option to generate a DSM.
  2. 2D Map: Select the option to generate an Orthomosaic.
  3. Output CRS: Select the output coordinate reference system (CRS) to use. If GCPs are included in the project, this option will locked to the GCPs' CRS.
    • Auto-Detected: the default option, automatically detected
    • Known CRS: select a specific CRS
    • Site Localization: select a local coordinate system
 
Note: When capturing a project with a LiDAR-capable device, the depth data will be processed automatically. For a list of compatible devices and for more information about how PIX4Dcatch uses LiDAR data, please refer to PIX4Dcatch FAQ.

Multi-upload to PIX4Dcloud / PIX4Dcloud Advanced

From the project dashboard, you can also upload multiple projects simultaneously.

  1. Tap the folder icon project folder icon to access the project dashboard.
  2. In the upper right of the screen, click on Select.

  5. To select the project processing options, please click here. The processing options and CRS will be applied to all the projects.
  6. After all images are uploaded and processing begins, a first email notification is sent for each individual project.
  7. After the processing is finished, a second email notification is sent for each individual project.
  8. The processed results can be viewed directly in the app and shared on PIX4Dcloud.
 
Tip: Multi-upload is possible for GPS and RTK projects.
 
Note: If one project is resumed and another project is new, the new project will inherit the processing options from the resumed project.
 
Warning: Multi-upload does not work in the following situations:
  • the projects have different processing options
  • the projects have different CRS
  • one project was already uploaded and another project is resumed
  • the projects have GCPs and marks

Process Locally with PIX4Dmapper or PIX4Dmatic

  1. Export the project files from PIX4Dcatch. For more information, please refer to How to export PIX4Dcatch projects (iOS/Android).
  2. Create a new project and start processing.
  3. (optional) Import Ground Control Points. For a detailed description of GCPs, please refer to Tie Points (GCPs, MTPs, and CPs).
  4. You can also upload the results to PIX4Dsurvey or PIX4Dcloud. For more information, please refer to How to import a PIX4Dmatic project into PIX4Dsurvey or How to upload or replace results to PIX4Dcloud.
  5. After the processing is finished, the results are available for further analysis in third-party reality capture/CAD/BIM software.
 
Warning: A PIX4Dmapper or PIX4Dmatic license (trial, discovery, OTC, monthly, and yearly) with a valid Support & Upgrade (S&U) is required to export the project data from Pix4Dcatch.
 
Tip: PIX4Dmatic can process PIX4Dcatch projects with marked GCPs if the project includes at least two marked GCPs. For more information: How to use automatic Tag Detection and manual GCP marking - PIX4Dcatch RTK
 
Tip: PIX4Dmatic can process PIX4Dcatch projects with LiDAR depth data using the Depth and dense fusion option, as well as having a Sky filter and Noise filter which benefits oblique imagery.
