NoteYou can bypass this section of the lesson by openningElastic_Import_Scene.mmf. This file can be found in the Tutorials/Elastics directory. You can then proceed to Set up the trackers and the survey points.

To load the image sequence

Select File > Load Sequence or click the Load Sequence icon.
The Load Sequence window appears.
In the Load Sequence window, browse to the location of the MatchMover Tutorials/Elastics directory, and select Elastic00.jpg, which is the first image in the sequence.
In the Load Sequence window, under Sequence Options, set Interlace type to Lower field first.
Under Camera Settings, set Frame Rate to 24 fps (Frames Per Second).
Leave Motion set to its default setting of Free.

Import the 3D mesh

To import the 3D mesh

Click the 3D space icon that is located in the top left of the Workspace.
The view switches to 3D mode. A camera icon and grid is placed in the Workspace.
Select File > Import, or right-click in the Workspace and select Import Scene from the pop-up menu.

The Import Object window appears.
In the Import Object window, select Wavefront Ascii Model (*.obj) from the Files of Type list.
Browse to the location of the Tutorial/Elastics directory, and select Box.obj.
A 3D mesh of the box appears, in wireframe, in front of the image plane. This mesh will now be used as a reference for the 3D tracking. This ensures that the solution will be consistent with this geometry even though this shot holds little parallax.
