Photogrammetry Error

  • 1.  Photogrammetry Error

    Posted 12-06-2023 22:49


    On of our users is getting the following error ("child process point cloud generation failed with exit code 3), which I think, is related to a failure to output a DSM model. 

    We can output the DTM, however that isn't automatically extracting features well at all (so, obviously prefer to get the DSM output working again).

    I realise this is light on detail, but will source further info when possible. Any comments in the interim would be appreciated.

    Kind regards,

    Hello Julius,

    could you please contact with your error? If possible, can you add to your email your zipped temp folder?

    Here a description where you can find it and what content you can ZIP:

    The temporary processing folder can be found on your computer at:


    LOGIN-NAME is the name that you use to log in to your computer.

    You will need to check this folder during your TBC Photogrammetry processing or when it crashes. As soon as you run another photogrammetric process, the folder will be overwritten, therefore try to get the content directly after your error or crash.

    ZIP the complete [uasbox] folder and send it to the support group. They can contact you and help you with further steps.

    Best regards,


    Thomas Widmer
