Image processing method and information processing apparatus

Abstract

An information processing apparatus includes a processor that detects positions of ball candidates from a plurality of time-series image frames. The processor adds a position of a second ball candidate to a second image frame subsequent to a first image frame based on a position of a first ball candidate and movement definition information. The first ball candidate is detected from the first image frame. The movement definition information defines a characteristic of a movement of a ball. The processor generates a plurality of trajectory candidates by combining a plurality of ball candidates detected from image frames of different times. The processor evaluates the plurality of trajectory candidates to determine a ball trajectory. The processor interpolates, when the ball trajectory is interrupted, between a starting point and an ending point of the interruption with a trajectory of a first person who moves from the starting point to the ending point.
