Project Assistant

The Project Assistant guides you through the process of creating a panorama in three easy steps. For an overview of the process, see the Video Tutorial.

The Project Assistant contains a button to switch PTGui from Simple to Advanced mode.

Step 1: Load images...

Press this button to select the source images. You can open multiple files at once, by holding down the Ctrl button (Windows) or Command button (Mac) while selecting files. Alternatively, files can be dragged and dropped into the PTGui window from (e.g.) Windows Explorer or Mac Finder.

The order of the images is not important at all: in the next step, PTGui will determine how the images overlap.

To remove images from the project, go to the Source Images tab.

Images can be rotated using the two arrow buttons at the right. This will rotate the entire panorama. The rotation of the thumbnails always matches the rotation of the images in the panorama.

Before proceding to the next step, PTGui needs to intialize the camera / lens parameters. Almost every digital cameras stores the focal length of the lens in the so called 'EXIF' header of the image file. If this data is available, PTGui will use it. If the images don't contain EXIF data, or if a non-rectilinear lens is used, the lens parameters should be manually initialized. Only a rough guess for the field of view or focal length is needed, the optimizer will determine the exact value later.

If the images don't contain EXIF information, and you have no idea about the lens parameters, just enter the following parameters:
Lens type: Rectilinear (normal lens)
Focal length: 35mm
Focal length multiplier: 1x
After completing the next step, you can read out the actual values of your lens here.

Step 2: Align images...

PTGui will analyze the images and look for matching features in overlapping images. At such matching features, 'control points' are added. The control points will be used by the Optimizer to align the images.

After the control points have been generated, PTGui aligns the images, optimizes and straightens the panorama. The Panorama editor then shows a preview of the panorama.

Other things you can optionally do at this stage:
  • Control point assistant: this brings up the Control point assistant window, which helps to determine whether the project has enough control points.
  • Align panorama: shows the Panorama Editor window, where the projection and orientation of the panorama can be modified.
  • Optimize: runs the Optimizer, which aligns the images such that the control points match as closely as possible. This button is disabled if the project does not need optimization.

Step 3: Create panorama

This switches to the Create Panorama tab, where the panorama can be rendered at the desired size and format.

レンズ設定タブ（Lens Settings tab）

メインウィンドウ：レンズ設定タブ （Main Window: Lens Settings tab） このページには、パノラマ撮影に使用されたカメラとレンズのパラメータが含まれています。 ほとんどの設定はPTGuiによって自動的に決定され、これらの設定を変更する必要はほとんどありません。 Lens Settings tab（レンズ設定タブ）は、 Advanced mode（詳細設定モード） でのみ表示されます。 シンプルモードでは、 Project Assistans（プロジェクトアシスタント） は、レンズタイプ、視野、焦点距離のパラメータのコピーを表示します。 継ぎ目の無い（シームレスな）パノラマを作成するには、ソースイメージを再配置（remapped）する必要があります（他にもworpedと呼ばれます）。 これは透視変換と見ることができます。ソース画像のパースペクティブは、生成されたパノラマのパースペクティブに変換されます。 適切な変換のために、PTGuiはあなたの写真を撮るために使用されたレンズを知る必要があります。 2つの重要なパラメータは、レンズのタイプと視野です。 いくつかのレンズタイプがサポートされています。 レンズの種類がわからない場合は、直線（通常）のレンズが最も適しています。 This can be seen as a perspective transformation: the perspective of the source images is transformed into the perspective of the generated panorama. For a proper transformation, PTGui needs to know what lens was used to take your pictures. The two key parameters are the type of lens and its field of view. Several  Lens types  are supported. If you don't know the type of your lens, it most likely is a rectilinear (normal) len...

Advanced / simple mode（詳細設定／シンプルモード）

Advanced / simple mode PTGui can operate in two modes: The  simple  mode is intended for new users, and is in fact sufficient for almost every panorama. PTGui starts with only the  Project Assistant  visible, generating a panorama fully automatically by following a simple three step process. During the process, other tabs become visible, but only the relevant settings are shown. The  advanced  mode allows experienced users to adjust every single parameter of the panorama. Most of these parameters are adjusted automatically by PTGui in simple mode, so the simple mode is recommended whenever possible. PTGui can be switched between the two modes by pressing the  Advanced >>  or  << Simple  buttons in the  Project Assistant .
