Template:V1.4 Option Detection

[[Image:{{{image}}}|thumb|400px|{{{titre}}}]] Detection settings determine the speed, quality and a few other aspects when it comes to scanning an image group looking for panoramas and stitching the images together. It is important to understand that the Detection Settings have two instances - Global, set from here, and Local, set for each image group, if need be. Whatever you set in this dialog will be the defaults for every newly created image group, you can then alter the settings locally on a per group basis using the Local Settings once the group is created.

  • Detection Quality - determines how much work will be put into finding matching areas and points in overlapping images. This setting is very CPU intensive and using High or Maximum can multiply the detection time from three to four times.
    • Standard: This is the default setting and, for most cases, is a good compromise between quality and detection speed.
    • High: Increases control point density and accuracy, but slows down the detection speed. Useful in cases with small overlap between images, bracketed photos, or other specific cases. Note: most experienced Autopano-ers set High as their default, as it usually gives better results without too much of a wait on a high-end computer.
    • Maximum: The most accurate, but also the slowest method. Used mainly for desperate cases. It can save the day, but prepare for a long wait. This method is also known to sometime produce an excess of control points that can actually ruin a good panorama, so use in extreme cases only.
  • Key Point / Image Pair: Set the number of control points per overlapping image pair. Keep in mind that too many control points will not lead to a better panorama. Anything above 100 is, in the generality of cases, useless. For the average user, 50 control points should be quite enough.
  • Force every picture to be in the same panorama: Self-explanatory. There are cases where you know a set of images belong in a single panorama, but Autopano Pro fails to detect a panorama at all, or leaves some of the images out. Checking this option will force Autopano Pro to always try and make a panorama of all images in an image group, no matter what. Note: if your workflow includes putting each image set in a separate folder prior to dropping them into Autopano Pro, you will want this option turned on by default.
  • Optimisation: By default, the two following options are checked and this setting should work fine most of the time. Turning those off will really speed up the detection of large panoramas (hundreds of files). The third option should be used in case of fisheye lenses.
    • Strong algorithm: Turn on/off the use of a stricter algorithm while optimizing after panorama detection.
    • Lens distortion: Turn on/off the lens distortion correction logic.
    • Advanced distortion: Check this option if you use fisheye lenses.
  • Project: You can modify the destination folder and the name syntax of the project files.
    • File name: Set a template for naming all detected panoramas. This will be the project file name if you decide to save it, and it will show in the Panoramas View, as a title for each panorama. Click the ? (question mark) button next to the text field to see the syntax used for the file name template.
      • %i / %I - short / long name for the first image in the panorama (short = filename; long = full path and filename)
      • %j / %J - short / long name for the last image in the panorama (short = filename; long = full path and filename)
      • %n - number of images used in the panorama
      • %g - auto incremental index
    • Directory: Set the folder where the project file will be saved when Auto save and close is checked
  • Automate: Autopano Pro is able to build great quantities of panoramas in a totally automated way. You can use the provided check boxes to choose what options will be enabled by default.
    • Auto crop: Crop the panorama to its usable pixels (i.e. non-black, containing image information). Same as the Crop tool in the Panorama Editor.
    • Auto color correction: Turn on color correction, as set in the Editor tab of the settings. Same as the Standard color correction switch in the Panorama Editor.
    • Auto render: Add the panorama to the Batch rendering interface and begin rendering as soon as the detection is completed.
    • Auto level: Adjust the level automatically.
    • Auto save and close: Save the project file in the source files' folder and close the panorama for later editing.
