APP/APG v2.0 Groups View


The Groups View is the area of the workspace allowing you group source images. Once the groups are created a panorama detection can be independently launched on each group. The detected panoramas will then be displayed in the Panoramas View.


The Groups Toolbar


Start all.pngDetect Seams, Stop all.png Stop All

This icon is used to launch the panorama detection in all currently open groups.

The Stop version of the same button is used to stop the detection process.

Group new.png New Group

This icon is used to create a new, empty group This is useful when splitting an existing group into several new groups. Using the mouse you can then drag and drop pictures taken from other groups into the empty newly created group. You can also directly import pictures from an open Windows Explorer window (or Finder on Mac) using the same drag and drop method.

This icon closes all currently open groups in one click.

An Image Group

The area of the GUI representing a group is shown in the above screen capture and contains the following:

  • A title; a unique group number and the status of the group.
  • One (1) large icon representing the main group action, i.e. the panorama detection.
  • Three (3) smaller icons used to adjust the group parameters.
  • A group data summary for quick reference on shooting parameters.

Start.png Detect, Stop.png Stop

Clicking on this button will launch the detection process on the pictures contained in the group, and once the process completed will display a preview of the panorama, or panoramas if more than one are detected.

If the groups were perfectly built, this process will produce a single panorama per image group and every panorama will contain all images within each group. If not, we can end up with several panoramas for one group, and even none if no link exists between the pictures or if the software is unable to find some (see Options next).

The Detect button changes into a Stop button during the detection process and can be used to cancel the detection before its completion.

Detection Settings

The settings in this dialog influence the way the source images are stitched together.

  • Detection Quality
    • Low is a good compromise between control points quality and detection speed.
    • Standard (default) increases control points density but slows down detection speed. In the case of a set of images presenting a small overlapping ratio this option can enhance the detection quality on the overall panorama. It is also used with panoramas presenting a lot a bracketing.
    • High very slow, mostly reserved to desperate cases (… worth a try before giving up).
  • Control Points / Image Pair : This is the number of control points used per image pair. Influences the number of control points exported to PanoTools as well as the overall detection quality.
  • Links Layout:
    • Free (default): This setting applies no shooting constraint (several rows and columns) to the detection process. Autopano is looking for all possible links between all images. It is possible that when using this mode the software will come up with “real false” links meaning that some images are indeed linked because they are very similar but in fact are not located beside one another (Example: a courtyard can present a lot of similarities because of its architectural symmetry). It will then be necessary to correct those wrong links using the Control Points Editor.
    • Single Row or Column: This only applies when the source images were shot consecutively. For example from left to right; in a row. Using this mode avoids the occurrence of “real false” links resulting from image similarities.
    • List all Models : Works with the Extended Save As.... This makes possible to use the links found between the images in a previous detection as a template for a new detection (assuming the source images were shot in the same pattern) in order to avoid ending up with real “false” links.
  • Force every image to be in one panorama: This option is useful when, as it happens with some panoramas, one or several source images are left out. This does not per say enhance the detection quality but instead will force the software to include this or these ignored image(s) in the panorama even if they do not present any links with the other images.
  • Detect links in:
    • One stack level (default): The software will look for all possible links between all images belonging to the same stack.
    • All stack levels: Autopano will look for all possible links between all images.
  • Project: You can here change the target folder along with the syntax used to name the project files.
    • Folder: the target folder where the project files will be saved when using the Save and close auto mode
    • Use relative path for image location in project:
    • Filename: the name of the .pano project file is generated using a special syntax template entered here.
  • Automate: Autopano can, by itself and a in a fully automated way, produce large quantities of panoramas. This set of options let you choose the software default behavior.
    • Auto crop: the panorama is automatically cropped to leave no empty area inside the resulting image boundaries.
    • Auto color correction (default): automatically compensate for color variations between source images.
    • Auto color histogram: apply an auto color level filter.
    • Auto render: automatically launch the final rendering process once the panorama detection task is completed.
    • Auto save: automatically save the panorama once the detection task is completed.
    • Auto close: automatically close the panorama once the detection task is completed. This option is often combined with Auto save.

This icon gives access to the Images Settings window allowing you to adjust your camera settings along with the Fisheye settings if you used that kind of lens. A special documentation page is dedicated to the Image Settings

Group addpicture.png Add Images

Used to add one or several images to the group.

Modifying Groups Content


Several options are available to organize the images:

  • Use the drag and drop technique. Select the images then drag and drop them into another group.
    You can combine the drag and drop with the SHIFT keyboard key to either move, either copy the files to the new group.
  • Use the contextual menu in the group view. Select the images then right-click to display the menu. You can then move the images to a new group, copy the images to a new group, and so on …. .
  • You can use the regular Ctrl+C, Ctrl+X, Ctrl+V, keyboard shortcuts to move or copy images from one group to another.
  • The drag and drop technique is also available from outside the software. Just select some images in the Windows Explorer or in the Mac Finder and drag and drop them in Autopano Pro. If you drop them in a group, the images will be added to this particular group, if you drop the images anywhere else inside the Autopano Pro window a new group will be automatically created with those images.

Source Image Viewer


When in the Group Window, it is possible to display any source image by double-clicking on its thumbnail. The integrated Image Viewer will then start and display a full size preview of the selected source image. This is very useful when refining image groups.

The navigation buttons provided at the bottom of the Image Viewer window allow for zooming and EXIF data display.

An interesting feature is also provided: synchronous browsing, as illustrated next. This feature can be activated by selecting the anchor at the bottom of the two windows containing the pictures you want to browse simultaneously.
