LUNCH/break time (approx. noon - 1pm)

Day 1 - Afternoon - IMAlign

IMAlign Essentials

• Using the mouse to rotate and translate 3D images
• Controlling the rendering of 3D images
• Selecting 3D images in the Tree View
• Selecting image data points in the 3D rendering window
• Performing interactive alignment and editing operations
• Saving your configuration

Sequential alignment of a set of 3D images

General initialization procedure

• Configure IMAlign for the ShapeGrabber Scanner
• Use the Image color mode
• Add an image set to the group
• Delete undesirable data points
• Lock the image set

Adding and aligning new image sets

• Add an image set to the group
• Manually align the new image set
• Check the overlap
• Match 1 pair of points
• Match N pairs of points
• Align the new image set using the iterative process
• Lock the alignment of the new image set

Optimizing the global alignment of a set of 3D images

• Unlock the alignment of all images
• Lock the alignment of one image
• Set the parameters of the image-alignment algorithm
• Save results in the group directory
• Save the results to an XYZ point cloud file
• Hole Editing feature

Trainees will now complete an Alignment of a set of scans.

Post-processing

• Reduce the amount of overlap in the set of 3D images
• (Estimate the IMMerge Step parameter)
