The Log Output bar contains valuable information about the steps and substeps of processing, the actions taken, the warnings, and the errors during the processing. It is an important piece of information during project processing as it helps in the early detection of errors.     

 
Access: 
  • On the Menu bar, click View > Log Output to enable the bar at the button of the main window. For information more about the displayed bars: Displaying bars or, 
    Log_Output.png
  • Click on Log Output bottom left panel in the PIX4Dmapper interface.

 
Important: 
  • Pix4Dmapper exports the log file (project_name.log). It is stored in the output folder project_name.
  • The log file displayed at the Log Output bar is cleared each time PIX4Dmapper closes. The next time the software is opened, the log file will start registering the different actions from scratch. 

Main window

It displays the log bar. The displayed information depends on the selected Levels and Options. If a keyword, character, or number is used in the Searching Engine, the displayed log only shows the strings containing these elements.

Levels filter

The Levels button allows filtering by the level of details of the log displayed on the main window. There are the following levels of detail:

  • [Info]: Displays general information printed in the log file. The text is displayed in black.
 
Example: It displays the used version of Pix4Dmapper: [Info]: Version = <2.2.15>.
  • [Warning]: Displays the processing warning messages that are printed in the log file. The text is displayed in yellow.
 
Example: [Warning]: Some geotags were invalid and therefore removed.
  • [Error]: Displays the processing error messages printed in the log file. The text is displayed in red.
 
Example: [Error]: Failed to open file <file_directory>!.
  • [Processing]: Displays the processing steps and substeps printed in the log file and their status. The text is displayed in green.
 
Example: [Processing]: Substep Camera calibration started.
  • [UI]: Displays the user's actions in the User Interface. The text is displayed in blue.
 
Example: It displays [UI]: Open Results Folder clicked when the user clicks the button Open Results Folder...

Options

The Levels button allows selecting the format of displaying options of the log on the Main window. There are the following options:

  • Full Headers: It displays the full headers (Date, Time, % RAM, % CPU).
  • Wrap Lines: It wraps the lines when the main window is too small.

Search Engine

It allows searching for specific keywords, text, numbers, and characters. The results of the search are displayed in the Main window.

Clear log

It deletes the log that is displayed in the Main window.

 
Important: 
  • The log file stored in the output folder project_name will not be deleted.
  • The Clear Log action can not be retrieved. Once the log is deleted from the main window, there is no way to bring it back.

  • Holden (Pix4D)

    Without reviewing the entire log its difficult to know. As they are warnings it may not be critical. Is processing failing at any stage?

  • Jose Freija de Jesus Soares

    Hi there, 

    can u tell me how to extract the log files from Pix4D Mapper?

  • Holden (Pix4D)

    The log file is located in the root project directory. It is a .log file that you can view in any text editor.

  • Jose Freija de Jesus Soares

    Got it,

    Thank you

    Hi,

    The issue you are experiencing is a common problem while your machine does not have enough RAM for the processing.

    Please reduce resources and shown in the image below and reprocess Step 3. 

    If it will not solve the problem, please follow our instructions from this article and reduce the Processing Options for Step 2.

    Let me know if you need anything else. 

    Regards

    Good day

    If there was a loss of power, how do i continue from where i left when the power comes back whilst was working in "read-only/processing" mode

    Hi Simbarashe, 

    You can't continue from where you left. However, you don't have to repeat the step that is already processed before power loss. For example, if you had a power loss during step 2, then you have to only process step 2 and step 3.

    Regards,

    Good day

    How do I command the system to start at step 2 and then step 3 without starting at step 1?

    Hi Simbarashe Kwashiwa,

    You cannot process Step 2 or 3 without processing Step 1. 

    If Step 1 is processed and you don't want to process it again, please uncheck the box of Step 1 and mark Step 2 and 3 as in the example below. 

    Regards
