The perspective tracker is able to track a flat plane which undergoes “perspective change” in respect to the camera. It kind of goes beyond scaling, rotating and translating. (1 extra degree of freedom)

Generally, use the perspective tracker when you track relatively large patterns on flat surfaces (a flat ground for example). It results in really stable and reliable tracks 🙂
