Abstract

Disclosed in the present specification is a sensing apparatus for making an inference about the motion of a moving ball, comprising: a sensor unit, which senses the motion of a ball pitched by a pitching device, and captures image frames of a predetermined region; a frame reception unit for receiving an image frame set captured by the sensor unit; a motion inference unit, which analyzes the image frame set so as to calculate a location change and a size change of the moving ball, and makes an inference about a three-dimensional motion of the ball on the basis of the location change and the size change; and a video generation unit for generating a video file, which renders the moving ball, by using the three-dimensional motion.
