1. A method comprising:
- receiving, at a computing device, image data from a camera;
converting, by the computing device, the image data to a YUV color space;
filtering, by the computing device, the converted image data based on intensity and a predetermined color to produce a filtered image, the filtered image being a binary black and white image; and
determining, by the computing device, a location of light emitted from a controller from the filtered image, wherein determining the location of light emitted from the controller from the filtered image comprises finding the largest contour around the white in the filtered image, and fitting a circle to the largest diameter of the contour.

10. A system comprising:
-
a camera; and a computing device coupled with the camera, the computing device comprising; a processor; and a non-transitory computer readable medium, coupled with the processor, the non-transitory computer readable medium comprising instructions to be executed by the processor to; receive image data from the camera; convert the image data to a YUV color space; filter the converted image data based on intensity and a predetermined color to produce a filtered image, the filtered image being a binary black and white image; and determine a location of light emitted from a controller from the filtered image, wherein the location of the light emitted from the controller is determined by finding the largest contour around the white in the filtered image, and fitting a circle to the largest diameter of the contour. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19)
