What is the Virtual Inspector?

The Virtual Inspector is a tool of Pix4D Cloud to analyze the project images in full resolution by exploring the 3D model. It is possible to highlight, share, and export 2D areas of interest for more insights. Inspections provide flexibility to document a project on the cloud web platform and/or for third-party usage.

How to access the Virtual Inspector

 
Information: The Virtual Inspector is only available under these conditions:
    • The project has been processed on the Cloud.
    • The point cloud or/and the 3D textured mesh must have been generated on the Cloud, meaning the Virtual Inspector cannot be used on outputs that were uploaded.
    • Project images were not captured using a fisheye lens camera (e.g. Bebop 2, GoPro).
    • For projects uploaded from Pix4D Desktop for processing, ensure the box Camera Internals and Externals, AAT, BBA is checked (default) in Process > Processing Options... > 1. Initial Processing > Calibration.


1. Go to Pix4D Cloud and log in with a valid Pix4D account.
2. Select a project.
3. Select the 3D view.
4. In the main window, on the right side of the view, click ic_inspect_black.png which opens the Virtual Inspector.
5. Navigate the model, zoom, and orient it to locate an area of interest.
6. Click on the model (green cross). It is possible to click different locations before starting the inspection.

How to use the Virtual Inspector

The Virtual Inspector allows to create and manage inspections that are annotation objects like distances, areas, etc.

1. On the right sidebar, click Inspection next to Name to set the name. Press the Enter key to save.
2. Scroll the list of images containing the point to inspect. The order depends on the distance to the point and its position on the image. Click ic_expand_black.png to display the images full screen. Capture information is displayed at the bottom.
3. There are three inspection features:

ic_draw_box_black.png Add a rectangular box (annotation) to highlight features on a specific image. Once drawn, the box cannot be moved. Delete it and draw a new one if needed. Clicking a box's name displays the respective image.

ic_pin_black.png Pin relevant images of the inspection. Other images are greyed out and are not accessible anymore after saving the inspection. Images containing boxes are automatically pinned.

ic_export_black.png Export and save to desktop an interesting section of an image.
Adjust the corners and move the crop zone to select the area. Unlock the aspect ratio for more flexibility. If the image contains a box, the default crop zone is automatically adjusted to it. Click EXPORT.

 
Tip:
    • If the green cross or the box(s) appear too small, lock the aspect ratio and reduce the resolution.
    • RESET reverts the crop zone to the full size and resolution of the image.

4. Add a description.
5. Click SAVE INSPECTION AS ANNOTATION. Alternatively, clickic_cursor_black.png to discard the changes and close the inspector.

Saved inspections are displayed with a blue icon on the 3D model.

    The virtual inspector is an excellent tool, but I'm having troubles with larger projects when using the "Inspect" tool.

    When I click an area on the point cloud, the sidebar is quick to bring up the thumbnails of the images containing that point, but it takes in interminable amount of time to load the larger preview image, or the full resolution images. I have quite a lot of photos, with the inspector finding 100+ images of that area. Is the inspector trying to load *all* of the full resolution images before showing me any of them?

    Hi Larry,

    I would be happy to help you but this time the issue is related to the speed of the Internet you have, and there is nothing we can do about it. I checked the projects you uploaded to the cloud, but for us, it takes a maximum of 3 sec to load the full resolution picture. How long does it take you?

    Best!

    Thanks Beata,

    I've confirmed that it loads much faster on a different connection, thanks for checking!

    Hi Larry,

    Good to know that you found another way to make it work!

    Best!

    I have a model of a small building. Less than 30 pictures were required. The model looks great but when I click on the inspection mode I get "Preparing the model for inspection". It never proceeds past this.

    I have tried uploading results from home.

    I have tried starting a new model.

    What am I missing?

     

    **Edit: Inspection mode works on a mobile browser (same internet connection).  But on the desktop on chrome, firefox, and IE won't work.

    Hi,

    I have checked on my side and apparently everything is working fine. I used the Inspection Tool with Chrome to inspect your Dome.
    Sometimes such processing can take a while and even if you got a message saying that your project is ready, sometimes it needs more time in order to finish to process the whole project and prepared the model for inspection.

    Let's us know if it is working now for you or not.

    Best

    Are there plans to make the Virtual Inspector work with projects which have been processed locally and uploaded to the cloud? We try to process most jobs locally to stay within the cloud processing limits, but clients are then unable to use the inspection tool when we upload those jobs to the cloud.
