Abstract
A system and method are provided for determining ball speed. The method comprises obtaining a video having a plurality of frames; analyzing each frame of the video to detect a position and a size of a ball moving through the frames; calculating the ball speed using the position and size determined from the frames, and a predetermined true size of the ball associated with the video; and outputting the speed of the ball. The analyzing can include applying operations of, background subtraction, noise removal, and motion filtering.
Claims20
A method of determining ball speed, the method comprising:
- obtaining a video having a plurality of frames;
- analyzing each frame of the video to detect a position and a size of a ball moving through the frames;
- calculating the ball speed using the position and size determined from the frames, and a predetermined true size of the ball associated with the video;
- and
- outputting the speed of the ball.
A non-transitory computer readable medium comprising computer executable instructions for determining ball speed, comprising instructions for:
- obtaining a video having a plurality of frames;
- analyzing each frame of the video to detect a position and a size of a ball moving through the frames;
- calculating the ball speed using the position and size determined from the frames, and a predetermined true size of the ball associated with the video;
- and
- outputting the speed of the ball.
An electronic device configured for determining ball speed, the device comprising a processor and memory, the memory storing computer executable instructions for:
- obtaining a video having a plurality of frames;
- analyzing each frame of the video to detect a position and a size of a ball moving through the frames;
- calculating the ball speed using the position and size determined from the frames, and a predetermined true size of the ball associated with the video;
- and
- outputting the speed of the ball.
