Perspective tracking system

A perspective tracking method comprising:

• capturing, using a computer-based system, an image frame wherein said image frame includes a location of an emitter and a location of a second emitter;
• determining, using the computer-based system, an area of interest based on the location of the first emitter and the location of the second emitter;
• determining, based on the locations of the first and second emitters, a spatial position, an orientation, and a size of the area of interest;
• wherein the capture of the image frame comprises measuring a light intensity of each of the first and second emitters over a detection threshold and applying a correction equation to the light intensity measurement that yields temperature-based offsets.

A computer program product comprising a non-transitory computer usable medium having control logic stored therein for causing a computer to track a perspective of an array of emitters, the control logic comprising:

• first computer readable program code for causing the computer to capture an image frame wherein said image frame includes a location of a first emitter and a location of a second emitter;
• second computer readable program code for causing the computer to determine an area of interest based on the location of the first emitter and the location of the second emitter;
• third computer readable program code for causing the computer to determine, based on the locations of the first and second emitters, a spatial position, an orientation, and a size of the area of interest;
• herein the first computer readable program code further comprises:
• computer readable program code for causing the computer to measure a light intensity of each of the first and second emitters over a detection threshold;
• and
• computer readable program code for causing the computer to generate a correction equation to the light intensity measurement that yields temperature-based offsets.
