      Inputs - PIX4Dcloud

       

       

      Inputs to PIX4Dcloud 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

      • 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
      RGB JPEG images
      .tif, .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: Orthomosaics cannot be generated from .tiff images with 10, 12, 14, and 16 bits-per-sample pixels. Please note that this applies only to orthomosaics, not reflectance and index maps.
      Note: PIX4Dcloud is optimized for projects with up to 4000 images and cannot accept more input images per project. The number of images that can be successfully processed depends on the characteristics of the project. For more information: How many images can PIX4Dcloud servers process?
      Warning: PIX4Dcloud/PIX4Dcloud Advanced alone doesn't support the processing of rjpeg and grayscale thermal images. PIX4Dmapper can be used to process those images. See P rocessing thermal images using PIX4Dcloud/PIX4Dcloud Advanced and PIX4Dmapper.

      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 results generated with other Pix4D products and uploaded to PIX4Dcloud via Share to Cloud (PIX4Dmatic and PIX4Dsurvey) have no size limitation on the files that can be uploaded.

      In this case, no images are processed, but in cases where results are generated with third-party software have the size limitations mentioned below when uploaded to a project in PIX4Dcloud.

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

      • Orthomosaic (.GeoTIFF),
      • DSM (.GeoTIFF),
      • Index (.GeoTIFF): NDVI map or other index maps
      • Point Cloud (.las, .laz),
      • 3D Textured Mesh (.obj).

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

      • Orthomosaic: one single GeoTIFF file supported, 50 GB maximum
      • DSM: one single GeoTIFF file supported, 50 GB maximum
      • Index: one single GeoTIFF file supported, 50 GB maximum
      • Point Cloud: one single LAS or LAZ file supported.
      • 3D Textured Mesh: one single OBJ+MTL+JPG set of files supported
        • OBJ: Maximum 1 GB.
        • JPG: Maximum 16k x 16k.
      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.

      Warning: As it is explained in this article, there is a 50 GB size limitation when uploading an ortho, DSM or NDVI to a PIX4Dcloud project. That means that a file bigger than that will not be imported. However, depending on the shape of the files it is not guaranteed that they will be displayed in the browser when they are bigger than 7.52 GB. The user will see a message informing about it in that case. This is especially critical when the files are coming from a corridor flight.
