Error while processing a project on Pix4Dcloud

A project may fail to be processed on Pix4Dcloud. If the problem is more related to output display (no evident failure or error message), other specific checks should be performed. For more information: Output is not displayed / feature is missing in the cloud.

Regarding the processing itself, several leads are recommended to be explored.

Inspect the input files

Check the input images, camera model parameters, and geolocation options. More information on the supported inputs in: Inputs.

Warning: Pix4Dcloud allows to process projects with minimum 6 images. When uploading the images from Pix4Dmapper, there is no warning message which is why the project fails if it does not comply with these minimum requirements.

Inspect the quality report

Note: The quality report is only available after step 1. Initial Processing is complete.

1. Go to the Files > Results section of the project.
2. Click the Quality report to download it.
3. Analyze the results. For more information: Quality Report Help.

Inspect the project files and generated outputs

Note: The list of downloadable items depends on:
    • The processing steps that are complete.
    • The selected outputs and formats.
    • The processing template applied or the type of images.

1. Open the project.
2. On the top right, click bu_download.png Download.
3. Click Export to Pix4D desktop. For more information: How to download results from the cloud.
4. Browse the output folders and check the results. For more information: Pix4D outputs with other software > by output.

(Advanced) Inspect the log file

1. Open the project.
2. On the top right, click bu_download.png Download.
3. Click Processing log to download the file.
4. Open the file with a text editor, e.g. Notepad++.

The project crashed on Pix4Dcloud servers

The project can crash on Pix4Dcloud servers due to lack of resources.

If the project was uploaded from Pix4Dmapper, try again:

  • Reducing the Processing Options for the outputs.
  • Ensuring the strictly necessary outputs are marked for their generation.
  • Defining a Processing area before uploading the project.

Check the Pix4Dmapper version

If the project is uploaded from Pix4Dmapper, ensure the Pix4Dmapper version run is the 4.5.6 or older. Projects created with the preview version 4.6.1 are not supported on Pix4Dcloud and a processing error occurs as a result.

In case Pix4Dmapper version 4.6.1 is used:

  1. If control points were present and already marked, their marks can be exported from the project in the 4.6.1 version.
  2. Downgrade the Pix4Dmapper application to its 4.5.6 stable version.
  3. Create a new project from scratch in the Pix4Dmapper version 4.5.6 or older.
  4. (Optional) Add the GCPs and import the marks exported beforehand.

    In some cases the selected camera calibration method fails wich will end up in a agarbage model even if all input images are fine. The same data used in the desktop version using alternate camera calibration works just fine


  • Momtanu (Pix4D)

    Hi Anders,

    Pix4D cloud uses the default 3D maps template if you are using Pix4Dmapper. The calibration method in this template is standard calibration. However, for certain projects (where the land is homogeneous, features are very few: agriculture, sand, forests etc), alternative calibration works best. So if you are processing a project which is homogeneous, it is best that you start the project in desktop, change the processing options and then upload the project to the cloud (from desktop): In that case, Pix4D will use the processing options you had selected.

    Hello Momtanu , can you help me solve my problem , I think this is exactly the issue I am problem ID is 67050. We have two SONY A65v Cameras , and some time ago we tryed and succeded making a mosaic out of it. Now, in this second test, we are not able to do so. Our cameras are geotagging correctly, and we have good overlap. what can be wrong with this.?

  • Momtanu (Pix4D)

    Hi Pedro,

    I worked with your dataset yesterday and could make it work. You will need Pix4Dmapper for this dataset if you are processing in fields cloud. In your case, Pix4D is reading the EXIF from the images (I ran the project with the default camera that was getting detected and the project failed). I have used SLT-A65V_28.0_6000x4000 from the database and ran step 1. It processed successfully. So he will need to start the project in desktop (as there is no option to change edit the camera model in the cloud), use image properties editor to change the camera model to the database one:

    All the images got calibrated but there was 300% difference in optimized camera parameters. Thus I loaded optimized parameters and processed step 1 again. I have processed only step 1 to save time. But step 2 and 3 should process successfully. Thus you cannot use pix4dfields cloud only as it will process with the default ag RGB template and the camera detected cannot be edited. You will need mapper.




  • Pedro Towers

    Hello Momtanu, thanks for your help. We could calibrate our camera and make both the point cloud and mesh from the image data set. The new issue is that when we try to process the mosaic, we cannot tick on the option to generate and export the mosaic, DTM and other products of part 3 of processing. How can we overcome this issue?



    The message says (not available with this edition). That means we make some mistake or that it is not allowed in trial version to get mosaic, and DTM?

  • Momtanu (Pix4D)

    Hi, It means you are using Pix4D discovery which does not include all the functionalities. You can use the trial version of Pix4Dmapper, it will have all the functionalities of the software. This is how you can get a trial: If you are unable to get a trial, you can reach out to us and we can activate a trial license for you. Thanks :-)

    Hola, estoy teniendo problemas procesando un trabajo de unas 2000 fotografías en el cloud. No me realiza en trabajo completo.

    Cada vez que lo subo me da un resultado diferente.

    A que puede deberse?

  • Alice (Pix4D)

    Hola Angel,

    ¿Te refieres al último proyecto que subiste a tu cuenta de Cloud? Creo que las imágenes del proyecto están dañadas. Además, ¿qué quiere decir con "Cada vez que lo subo me da un resultado diferente"? Estas sobrescribiendo el proyecto cada vez? En este caso no puedo ver las diferencias en los diferentes proyectos.


  • Conrad Wright

    Our processing error relates to a series of new ALTUM datasets, but we cannot find anything wrong in the logs or the report.  We simply have no outputs.  We have emailed support but not heard anything.  Could you help us investigate the problem?  

  • Momtanu (Pix4D)

    Hi Conrad, Can you let us know the ticket number? We can have a look. You could also provide your email ID and project name here.

  • Jose Jesus Castro Jimenez

    Hola, podrían apoyarme en saber porque marca error mi proyecto en Cloud? El archivo LOG no indica errores o algo parecido.

  • Alice (Pix4D)

    Hola José Jesus,

    ¿Podría reprocesar con la siguiente opción de procesamiento de la nube de puntos y decirme si resuelve el problema?

    • Densidad de los puntos -> "Baja (Ràpido)"
    • Deseleccione "Multi escala"

    Espero que esto ayude.


  • Jose Jesus Castro Jimenez

    Hola Alice,

    Puedo hacer esos cambios en "Cloud" o los hago en mi aplicación de escritorio y vuelvo a subir el proyecto?


  • Alice (Pix4D)


    Simplemente cambie las opciones de proceso en la versión de escritorio y suba el proyecto a la nube para procesarse de nuevo.

  • Holden (Pix4D)

    Hi there. If I understand you are trying to open a project processed on the cloud locally, correct? This looks like some of the images are missing. Can you look at how many images are on the cloud project and how many files are in the local image directories? Are they named the same?

  • Tristan Steventon

    I have recieved this error while processing in the cloud platform, it appears to have run out of disk space Project has 3922 images so just short of the 4000max, is there something that we can do to fix this

  • Blaž (Pix4D)

    Hi Tristan, the error that you receive shows that the calibration was successful but the processing stopped after the dense point cloud was generated. 

    If you are uploading from the Pix4Dmapper, then you can change the Processing Options to generate fewer 3D Points or introduce a processing area before uploading the project for processing on Pix4D Cloud. This will reduce the number of generated points and probably fix the issue that you face. 

  • Danilo Zinader

    Olá estou na versão trial. Meu projeto tem 2300 imagens e está a 24horas em processamento. A mensagem que aparece é para aguardar que um email será enviado quando o processamento finalizar. A dúvida é se meu projeto será processado e devo aguardar ou se o processamento excedeu o número de imagens na versão trial? grato!

  • Beata (Pix4D)

    Olá Danilo,

    Os usuários de trial podem processar 1000 imagens e / ou criar 3 projetos durante o período de experiência. Seu projeto consiste em 1300 imagens e excede a cota permitida. Você poderia tentar com um projeto menor? Mais informações sobre o subsídio podem ser encontradas em Pix4Dcloud - FAQ.


  • Susan Myers

    Please let me know what is going wrong so I can get this project to process properly in the cloud.  I have attempted to upload this project both prior to running Step 1, and again after running Step 1 using Pix4Dmapper (4.6.1).  I am attempting to upload for cloud processing and once it gets uploaded, shortly after I receive an email telling me it will take 4.5 hours to process, I receive a subsequent email telling me the project has failed due to an unknown cause. None of the suggestions provided in the article above appear to be the cause. Could it be because I am using a "deprecated" coordinate system for GCPs and Output?  Or...I am just now reading about problems with using the latest version of Pix4Dmapper (4.6.1) - and this may be the reason the project uploads are failing?  Do I need to install Pix4Dmapper 4.5.6 instead in order to get the project upload to work properly?

    Please help me figure out what I need to do differently so the project will process properly in the cloud and not crash.

    Attempting to upload a project of:

    - Fewer than 1000 images.

    - Areas have sufficient overlap. 

    - Image quality is good. 

    - Quality Report from Pix4Dmapper processing Step 1 shows great summary and quality results:

    Hi Susan,

    As you correctly noticed, Pix4Dcloud does not support projects uploaded from the Pix4Dmapper preview version 4.6.1. Uploading with this version would trigger a processing error. Recreating the project with version 4.5.6 and uploading it again would solve the issue. Notice that GCP marks can be exported and imported from one version to another, more information in How to export the marks of GCPs/Manual Tie Points in the GCP/MTP Manager.
