This page is a stub, please expand it if you have more information.In outside-in tracking, the tracking camera(s) is placed in the external environment where the tracked object is within its line of sight. The tracking camera uses the changing views of the object itself to determine the object's position in space. A problem outside-in tracking often encounter is occlusion.
The opposite of outside-in tracking is inside-out tracking.
