Error while processing a project on PIX4Dcloud

Follow

A project may fail to be processed on PIX4Dcloud for different reasons. When this happens, an email is sent to the project owner. Several leads are recommended to be explored.

If the problem is more related to output display (the outputs are generated but something in the display doesn't work or no email is sent as error notification), other specific checks should be performed. Please visit: Output is not displayed / feature is missing in the cloud.

1. Inspect the quality report

When there is a processing error, the PDF quality report is normally sent via email to the project owner. If this is not the case, go to the section Inspect the log file.

  1. Download the PDF report from the email. Alternatively, open the project in the Error status, then click Quality report to download it.
  2. Analyze the file with the Quality Report Help.
  3. If no evident error is found, go to Inspect the log file.

2. Inspect the log file

When there is a processing error, normally an error is logged in the log file that is generated while processing. If there is no log file (and no quality report) generated instead, it is highly probable that The project crashed on PIX4Dcloud servers.

To download and inspect the log file:

  1. Open the project in the Error status, then click Processing logs to download the file.
  2. Open the file with a text editor, e.g. Notepad++.
  3. In the processing logs document, look for (CTRL+F) the following string: [Error]. 
  4. Go to the Pix4D Documentation or to your preferred search engine and search for the error code/description.
 
Example: If the error logged is [Error]: Error e0046: Processing failed. No calibrated cameras, look for Error e0046 in the search engine.

3. Inspect the input files

Perform some basic checks on the input files:

 
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 this minimum requirement.

The project crashed on PIX4Dcloud servers

The project can crash on PIX4Dcloud servers due to lack of resources. This can happen if the project is too large or the processing effort exceeds PIX4Dcloud servers' capabilities. More information at: How many images can PIX4Dcloud process?.

If the project was processed directly on PIX4Dcloud:

  • Create a new project with a reduced number of images.

If the project was uploaded from PIX4Dmapper, reopen the project in PIX4Dmapper, then try choosing at least one of the following options:

  • Reducing the quality of Step 2 outputs in the Processing Options (defining Menu Process > Processing Options... > 2. Point Cloud and Mesh > Point Cloud > Point Density > High (Slow) and Menu Process > Processing Options... > 2. Point Cloud and Mesh > 3D Textured Mesh > High Resolution can potentially lead to a server crash for large projects due to high RAM usage).
  • Reducing the number of images.
  • Ensuring the strictly necessary outputs are marked for their generation.
  • Defining a processing area.

Then upload the project to PIX4Dcloud for processing again.

    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

    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): https://support.pix4d.com/hc/en-us/articles/202558589-How-to-upload-project-files-from-desktop-to-cloud. 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 facing.my 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.?

    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?

    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: https://support.pix4d.com/hc/en-us/articles/202560729-How-to-get-a-trial-of-Pix4D-Desktop. 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?

    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.

    Saludos

  • 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?

    Saludos!

  • Alice (Pix4D)

    Hola,

    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.

    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.

    Hi,

    I am receiving [Error]: Error e9034: Problem uploading item to the cloud.  The upload fails at 0% progress.  I had received this same error when using the prior version 4.5.6, so just updated Pix4Dmapper to the current latest Version 4.6.3. 

    Is the error due to my output coordinate system, NAD_1983_StatePlane_Nebraska_FIPS_2600_Feet (deprecated)?  Or is it due to other processing options settings?

    Thank you. :)
