1. A method, comprising:
capturing, using an image capture device, an image of an area containing at least a first fixture;
identifying physical location and positioning information associated with the image capture device;
identifying pixel coordinates in the image of the at least first fixture in the image by performing image processing of the image including a first thresholding process and a second thresholding process, wherein the first thresholding process generates a first thresholding process image including a plurality of pixels, each pixel of the plurality of pixels having a value of black or white and the second thresholding process generates, using a threshold value based on a neighboring area of pixels, a second thresholding process image;
pixel-by-pixel processing the first thresholding process image and the second thresholding process image to generate a third image; and generating a final image
by processing, using an OR function, the third image and the first thresholding process image;
and
converting pixel coordinates of the at least first fixture in the final image into physical coordinate information associated with the at least first fixture.
