Method and apparatus for computer vision analysis of spin rate of marked projectiles

Methods and systems for determining a spin rate of a projectile are provided. A receiving module receives a video of a launch of a projectile in which the projectile having at least one marking disposed thereon. A segmenting module segments a plurality of shapes of the projectile from the video. The segmenting module includes a sensitivity module configured to increase a sensitivity of the video to find the projectile in the video. An extraction module extracts at least one column of pixels of the at least one marking from the shapes. A generating module generates a stripe pixel column history image from the at least one column of pixels. A calculating module calculates a spin rate of the projectile from the stripe pixel column history image.
