If the project contains more images than will fit on the screen and you are doing a lot of work with the Thumbnail Window, try dragging the separator below the Thumbnail Window down so that the images are displayed in more than one row.
Clicking the button will switch to thumbnail mode (the default when a project is loaded or created). If the camera orientation is known for an image, the image will be displayed rotated so that the object is nearly upright - this may be a different orientation to the original image on disk.
You can select one or more thumbnails using the mouse or keyboard. Click on an image selects it. Dragging around a region of images will select or deselect all of them. Holding down CTRL will add or remove it from the existing selection. Holding down SHIFT will add or remove all the images between the last selected image and the current one. The cursor keys can also be used to navigate around the thumbnails.
The thumbnails are initially shown in the order in which they were added to the project ("project order"). You can change this when displaying in details mode (see Organising the images in details mode). When multiple rows of thumbnails are visible, the images are sorted down the rows then across the columns.
Clicking the button will switch to details mode. Each image is displayed as a row in this mode with the various information associated with it in columns to the right of the image name as shown in Figure 3.3.2. The contents of the columns are described in the Image properties section.
You can sort the images on any column by clicking on the column header. Clicking a second time reverses the sort order and a third time returns to project order. An arrow in the column header shows which column if any is sorted. The sort order affects the ordering of the images when displayed in thumbnail mode.
This section describes the properties that are associated with each image and how they can be affected. You can see the properties for an image by hovering the mouse over it in thumbnail mode or by switching to details mode using button.
By default this is the filename of the image (without the path or extension), but if you wish you can edit this to be more meaningful. This is useful in the thumbnail view where this is the only information displayed next to an image.
Most images are described as "normal" which means that the mask associated with the image will be used to generate the geometry and the colour information in the image will be used to generate the texture.
You can change the type of selected images from the "projected stripes" if the image was not already of that type. This will mean the image is only used for point cloud generation. If the type is already set to "projected stripes" then selecting this menu item means the image is treated as normal. menu. Selecting will set the type to

Images can be marked as "rejected" by selecting them and then choosing the menu item that means that subsequent operations will ignore this image. In the thumbnail mode, a cross is drawn over the image. By default, images will be "included".
When an image is loaded into 3DSOM Pro for the first time, the software automatically attempts to find where the camera that took the image was positioned relative to the object. It does this by identifying the calibration target(s) in the image. The camera elevation and rotation angles are displayed in this field (to the nearest degree) as well as a number representing the distance to the object.
In some cases this field will indicate that the camera location is not known for an image. Such an image will be marked as rejected since without knowing the camera position, it cannot be used. To manually specify the camera, use menu item as described in the Adding texture underneath an object tutorial.
This field defines an ordering of the images according to which 3DSOM Pro thinks contributes the most information. There are several operations that process images using this order, such as surface optimisation and texture generation.
This field displays the full pathname to the image. If the thumbnail image has not been loaded, this will be the last known location of the image. When the thumbnail is first loaded, 3DSOM Pro will look for the image in its last known location. If it can't be found it will look in the same directory as the project file, and if it can't be found there you will be prompted to locate the file.
The menu item and the menu item can be used as shortcuts for selecting images. Note that operations that usually work on selected images will be applied to all images if none are selected.
Choosing the menu item will take any unloaded thumbnails from the currently selected images and try and load them from the image files on disk. If all the selected images have already had their thumbnails loaded then they will all be refreshed from disk.
Use menu item to add new images to the project. You will be prompted to select one or more files from disk and then each will be added in turn. As the images are added, the camera position is calculated. If this fails, usually because the calibration mat isn't in the photograph, you will be notified and the image will be rejected. You will need to align these images by hand using the Align Wizard.
Note: 3DSOM Pro will only operate on images that are all the same size. Images of different sizes can be added to the project for convenience, but will be marked as rejected.
To remove some images from the project, select them and then choose menu item. This will leave the image intact on disk, but will destroy any mask created in 3DSOM Pro and remove it from the project permanently.
Use menu item to replace a set of images containing the calibration target(s) with replacement images taken from the same orientation without the need for a mat. The thumbnails must have been loaded to allow 3DSOM Pro to determine the camera position and rotation from the image features. This function can then be used to replace the images with corresponding images taken from precisely the same viewpoints. This can be useful for a fixed hardware configuration with, for example a computer controlled turntable. A set of shots can be taken with the mat placed on the turntable for calibration. Then the mat can be replaced with the object and another set of shots taken from the same positions.

Choosing menu item places a copy of the selected image in the Windows clipboard so that it can easily be pasted into an external editor. The image will have been subsampled and colour adjusted if these options are chosen so it matches its use in texturing.
Once the model geometry has been generated, you can choose the menu item to blend just the selected image into the texture map.
The "included" (no longer menu item will mark the selected images as rejected) so that they are used for subsequent operations. Note that all the "included" images must be the same size and must all have a defined camera position - if this is not the case you will be unable to change their status using this command.
The menu item will mark the selected images as rejected so that they are ignored for subsequent operations including masking, surface generation and texture generation. Images that are rejected can be deleted from the project and may also be aligned.
The menu allows you to operate on the masks associated with just the selected images.
