Motion blur is a result of finite acquisition time of practical cameras and the relative motion between the camera and moving objects. We present a method for speed measurement of spherical objects using motion blurred images captured by a digital camera. The object is assumed under a straight line uniform-velocity motion, and the speed is calculated according to the imaging geometry and blur extent estimates. We have established a link between the motion blur information of a 2-D image and the speed information of a moving object. Experimental results are presented for the real-scene images.
