The problem with unaligned regions can occur if there are not enough tie points between subsets. If some of such image subsets of the complete dataset are not aligned with each other, they will be grouped into individually aligned parts (so-called "Components"). The components are displayed as a tree structure in the chunk's contents of the Workspace pane. The components feature has been implemented starting from Agisoft Metashape 1.7.0. 

The tutorial describes the basic steps to follow in order to align and merge alignment components with the help of markers (available only in the Professional edition).

For the sample dataset, we have used the images of the sports shoe, which consists of the two sub-sets captured in the same conditions: of the top part and bottom part. All images have been processed in a single chunk.


Load images

1. Select Add Folder or Add Photos command from the Workflow menu. 

2.  In the Add Photos dialog box browse to the folder containing the images and select files to be processed. Then click the Open button. 

3. Selected images will appear on the Workspace pane.

Align photos 

1. Select Align Photos from the Workflow menu. 

2. Set the parameters in the Align Photos dialog: 

3. Click OK button to start photo alignment. After the alignment is finished see the results in the Model view (if the alignment has been split into several components, only the first component will be shown by default in the Model view):

To switch the display in the Model view to the desired component double-click on its label in the Workspace pane:

Working with components 

The components into which the camera alignment has been split after the Align Photos operation are displayed in the  chunk's contents of the Workspace pane:

To align components with each other manually use markers.  It is required to use at least 3 markers that do not lay on the same line. 


  • in each of the components, a hint with an epipolar line works, so the markers can be placed rather quickly. Having placed a marker on the first image (using Place Marker > New Marker command from the context menu in the Photo view mode), on the next image there will be a line along which this point has to be searched. When the proper location is found use the corresponding marker label in the context menu Place Marker section of the Photo view.
    After defining two projections of the marker, on the remaining images of this component, there will already be a gray flag that suggests the marker projection location, so you just need to pin it on a couple of additional images (click on the gray flag and drag to the proper location - the projection will be then highlighted with the green flag).


After placing the desired number of markers double-click on the second component in the Workspace pane to make it active, and repeat the marker placement operation, using the existing marker selection from the Place Marker submenu of the Photo view context menu. Make sure that the same marker is used for the same real object feature that is seen on both components.

After all the components are aligned, select them in the Workspace pane and then use the Merge Components command from the context menu.
