Claim One:
1. A method of assessing a resolution of an optical sensor, the method comprising: obtaining an image from the optical sensor; thresholding the obtained image to generate a binary image of pixels having contrasting colors using a first threshold value; selecting a target area from the binary image; increasing the first threshold value to generate a second threshold value; thresholding the selected target area using the second threshold value; tagging at least one pixel at a center of the selected target area; processing pixels surrounding a tagged pixel, tagging those pixels that are a lighter color of the contrasting colors; in response to a tagged pixel being at an edge of the selected target area, determining an orientation of an object in the selected target area based on the edge of the selected target area; and in response to not tagging a pixel at the edge of the selected target area, decreasing the second threshold value and repeating the thresholding, tagging, and processing steps.
