Abstract
A method and apparatus for measuring a speed of an object is provided. The speed is measured by taking a video of said object moving across a span. The object may be a baseball thrown from the pitcher's mound to home plate. The invention may include a device that with a video camera, a display screen and a control interface. The device generates a video of the object moving from a start point to an end point. The video frames for the start point and the end point are identified and the time span between the start frame and the end frame is determined. A distance between the start point and the end point is also determined. The speed of the object is then calculated from the time span and the distance. The information may then be displayed including a path trace and the calculated speed.
