Inputs

Pix4Dcloud's inputs can be images and text files with ground control points coordinates for cloud processing or 2D/3D results for visualization.

Inputs for processing

Pix4Dcloud inputs for processing are:

 
Note: A custom .p4d file (containing customized processing options, custom geolocation files, a processing area, etc..) can also be uploaded to Pix4Dcloud if the project is created in Pix4Dmapper and from there uploaded for processing. More information in: How to upload project files from Pix4Dmapper to Pix4Dcloud.

Images

Pix4Dcloud is optimized for projects with up to 4000 images. The number of images that can be successfully processed depends on the characteristics of the project. For more information: How many images can Pix4Dcloud process?

  • At least 6 images are required.
  • The formats in the following table are supported.
 
Warning: Do not modify images, i.e. do not rotate or edit the images. Modifying images alters the geometrical properties of the camera and may deteriorate the quality of the results.
Extension Description
.jpg, .jpeg JPEG images
.tif, .tiff Monochromatic TIFF
Multi-band TIFF (RGB / Infrared). See supported multispectral cameras.
1 layer (no pyramid, no multi-page)
8, 10, 12, 14, 16 bit integer, floating point
 
Note: Orthomosaic cannot be generated from .tiff images with 10, 12 and 14 bits-per-sample pixels. Please note that this applies only to orthomosaics, not reflectance and index maps.
 
Note: For technical limitations with our server, the maximum number of input images that can be processed per project on Pix4Dcloud is equal to 4000. More information about image allowance at Pix4Dcloud - FAQ.

Ground Control Points (GCPs) file

Ground Control Points (GCPs) are used for precisely georeferencing the project.

 
Important: This type of file can be uploaded only with Pix4Dcloud Advanced in order to automatically detect and mark GCPs on the images.
It is still possible to include GCPs into a Pix4Dcloud dataset. To do so, upload the project files from Pix4Dmapper as described in How to use GCPs for processing on Pix4Dcloud.
Extension Description
.csv

A text file containing from four to seven columns per line and a comma (,) to separate the values. No header included.

  • Four columns: ID, coordinates
  • Five columns: ID, type, coordinates
  • Six columns: ID, coordinates, Accuracy Horz, Accuracy Vert
  • Seven columns: ID, type, coordinates, Accuracy Horz, Accuracy Vert

All GCPs requirements and more information about the GCPs import format can be found at: AutoGCPs detection functionality.

Inputs for visualization

A dataset can consist of uploaded results only. In this case, no images are processed but the uploaded files are processed for their web-visualization and optimization.

The photogrammetric files that can be uploaded and displayed as results are the following:

  • Orthomosaic (.GeoTIFF),
  • DSM (.GeoTIFF),
  • NDVI (.GeoTIFF),
  • Point Cloud (.las),
  • 3D Textured Mesh (.obj).

There are some limits in terms of file size and formats for file uploads:

  • Orthomosaic: one single GeoTIFF file supported, 7 GB maximum 
  • DSM: one single GeoTIFF file supported, 7 GB maximum 
  • NDVI: one single GeoTIFF file supported, 7 GB maximum 
  • Point Cloud: one single las file supported.
  • 3D Textured Mesh: one single obj+mtl+jpg set of files supported, 1 GB obj maximum.
 
Information: Check How to merge the Tiles of the Point Cloud to merge the tiles that were created in Pix4Dmapper.
 
Warning: If you are uploading the 3D Mesh, read our recommendations for the Mesh upload here.

    What is the maximum megapixel size of an image that can be processed in Pix4D Cloud? I keep reading about the number of images limit, but never the size of images. I'm scoping out the options for mapping with a 150mp camera

  • Alice (Pix4D)

    Hi David,

    Which camera are you using?

    4000 is the technical limit for the size of a project on Pix4Dcloud but this value has been defined based on a standard resolution value. 930 images at 150 MP will not process successfully on our Cloud servers.

    A large-frame add-on can be purchased for our desktop product, Pix4Dmapper, but 930 images at this resolution is more than a challenge. You can contact sales if you want to try this option or you might want to consider other solutions (UltraMap, Inpho, LPS, ...)

    Hi I would like to import the cloud generated on pix4D desktop to pix4Dcloud in order make it available for some client.

    How can I do it, without restarting from zero the process on pix4D cloud?

    Tks 

    Michele

    Ciao Michele,

    As explained in the last section of this article, a dataset can consist of uploaded results only. You can find more information on how to upload results and outputs at How to upload results and outputs to Pix4Dcloud. Let me know if you need additional clarifications.
