The child process Surface Extraction failed with exit code -1.

  • 1.  The child process Surface Extraction failed with exit code -1.

    Posted 2 days ago

    Hello,

    I am new to the board.

    had some problem with TBC aeriel photogrammetry. I receive the eroor error: The child process surface extraction failed with exit code -1.

    I imported aerial survey data (50 images). I get the error when creating result objects (orthomosaic). The adjustment is fine, no errors.

    The error also occurs with old flight data that has already been processed and result objects has been created. So it is not due to the data.

    What has changed in TBC 2025.20 since then: a new license key has been entered in the meantime. All required modules have been activated by the key.

    Best regards

    Juergen
