Autopano - Preferences... - Detection

Warning Changes to the Preferences in the detection settings will be applied by default to the entire new image group created.

These options affect the way in which the pictures will be connected to each other. The detection step corresponds to when Autopano analyzes the images and assigns links to them with the use of significant points called control points.
If you make a mistake, you can use the "Reset default values" button.

Detection tab

Detection (manual)

  • Quality of detection:
    • Standard: (default) Increases the density of the points at the expense of the detection speed.
    • High: Useful if one, several or all images are ignored. Very slow, reserved for desperate cases.

  • Number of control points: Affects the number of control points exported to Panotools as well as on the detection quality. 50 (default value) seems to be the best choice in the majority of cases.

  • (Autopano Giga Autopano Giga only) Filtering model: lets select the detection algorithm.
    • Automatic: (default) let Autopano uses one or several models depending on the source images EXIF data to find control points.
    • Similarity: (fast approximation) to use with linear images shot at long focal (between 24mm to the infinite).
    • Homography: (complete model in image plane) to use with linear images shot with short focal lengths or in case of aerial shots.
    • Spherical: (complete model on the sphere) to use with fisheye images.


  • Layout:
    • Free: (default) Autopano calculates all the possibility of links between the images. This does not exclude the false links that could be created if your images contain many similarities (images linked by their similarities but in reality are not close to each other).
    • Single row or column: This can be used if the images were taken consecutively and on a single row. This method avoids the false links caused by the similarities of images.
    • Templates: Here you will find the templates that were previously saved with the Save as template feature.

  • Force every images to be in one panorama: All the group images will appear in the panorama. This option is useful when one or more pictures are ignored in certain panoramas. This will not improve the quality of detection but will force the image(s) to be reflected in the resulting panorama even if these images have no connection with the images of the panorama.

  • Detect links in:
    • The reference level: (default) Looks for all the possibilities of links between the images with the same bracket level.
    • All stack levels: Looks for all possibilities of links between the images.

  • For a stack:
    • Use hard links: Lets you precisely superimpose the different images of the same stack without assigning control points to them.
    • Detect control points: This uses the control points as a reference to superimpose the different images in the same stack.


  • Folder:
    • The ... button lets you select the directory of your choice.
    • Click on the Autopano 250 icon help.png icon for a description of the symbols that make up the models (syntax) of the file name:

Folder template syntaxes

  • Filename:
    • Name of project file (.pano).
    • Click on the Autopano 250 icon help.png icon for a description of the symbols that make up the models (syntax) of the file name:

  • Use relative path for image location in project: This is useful if you want to transfer the completed project to a third support (USB key, hard disk, CD, etc.) so that it can be opened on another machine.


  • Auto crop: automatically frames the panorama.
  • Auto color correction: (default) automatically standardizes the panorama’s colorimetry.
  • Auto color histogram: automatically applies a color level.
  • Auto render: automatically launches the rendering.
  • Auto save: automatically saves the project (.pano).
  • Auto close: automatically closes the project window. We recommend to tick “Auto save” when using this option.
