Systems and methods for viewing stereoscopic video images are disclosed. In one example, a stereoscopic video imaging and tracking system can include a first video camera to generate a first video feed of a subject, and a second video camera spaced a distance from the first video camera to generate a second video feed of the subject, wherein the first video camera and the second video camera are directed toward a convergent point to provide a stereoscopic image of the subject. The system can also include a tracking system to cause the first video camera and the second video camera to follow a tracking point to maintain stereopsis of the subject, and a zooming device associated with the first video camera and the second video camera. The zooming device can provide variable magnification of the stereoscopic video image.

The system of claim 4, wherein the head mountable stereoscopic display provides a split field of view to enable an operator to view both natural surroundings and the stereoscopic video image while wearing the head mountable stereoscopic display. 6. The system of claim 4, wherein the first video feed and the second video feed are wirelessly communicated to the head mountable stereoscopic display. 7. The system of claim 4, wherein the first video feed and the second video feed are communicated to the head mountable stereoscopic display through a wired connection. 8. The system of claim 4, further comprising a chart viewing system configured to display one or more pages of a chart on the head mountable stereoscopic display. 9. The system of claim 2, wherein video display comprises a single video screen, wherein the first video feed and the second video feed are optically separated using at least one of shutter separation, polarization separation, or color separation. 10. The system of claim 9, further comprising at least one pair of viewing glasses configured to be synchronized with the video display to enable at least one viewer to view the optically separated stereoscopic video image. 11. The system of claim 1, wherein the subject is a patient in a medical setting. 12. The system of claim 1, wherein the subject is a patient is a dental patient, and the tracking point or the convergent point is at or about dental patient's intraoral cavity. 13. The system of claim 1, wherein the first video camera and the second video camera zoom together, and wherein the zoom is at least one of an optical zoom or a digital zoom. 14. The system of claim 1, wherein the first video camera and the second video camera each zoom and provide an image with a magnification power of at least about 4 times. 15. The system of claim 1, wherein the first video camera and the second video camera each zoom and provide an image with a magnification power within a range from about 1 time to about 20 times. 16. The system of claim 1, further comprising positioning the first video camera and the second video camera at a distance from about 5 inches to about 96 inches from the subject. 17. The system of claim 1, wherein the tracking point is an optically trackable marker configured to be positioned at the subject to enable a direction of the first video camera and the second video camera to be adjusted based on a change in a location of the optically trackable marker. 18. The system of claim 17, wherein the subject is a dental patient, and wherein the optically trackable marker is configured to be positioned on a dental retractor located in or about the patient's intraoral cavity. 19. The system of claim 17, wherein the optically trackable marker is configured to be placed on a body surface of the subject. 20. The method of claim 1, wherein the tracking point comprises at least two radio frequency markers and the convergent point is determined relative to the at least two radio frequency markers. 21. The system of claim 1, wherein the convergent point is a virtual point that has an x, y, and z axis distance from the tracking point and the convergent point is maintained in relation to the tracking point as the tracking point moves. 22. The system of claim 1, wherein the convergent point is at the tracking point. 23. The system of claim 1, wherein the tracking point is a mobile marker configured to be located on a hand held instrument. 24. The system of claim 1, wherein at least one of the first video camera or the second video camera are coupled to a motor or multiple motors to enable an angle at which the first video camera and the second video camera are directed relative to one another to be changed, the angle to be changed based at least in part on a distance of the video cameras from the patient's intraoral cavity to maintain stereopsis of the stereoscopic video image independent of the distance. 25. The system of claim 1, further comprising a light source configured to provide illumination of the subject, wherein the illumination is sufficient to enable the first video camera and the second video camera to zoom to the magnification while maintaining a depth of field for the stereoscopic video image.
