Abstract
A method for viewpoint selection assistance in free viewpoint video generation includes: executing acquisition processing that includes acquiring three-dimensional information with respect to a subject on a field by using a plurality of cameras placed around the field; executing first identification processing that includes identifying a path of a ball for a predetermined period based on the three-dimensional information; executing second identification processing that includes identifying at least one player located within a predetermined distance from a position of the ball for a predetermined duration of time or longer in the predetermined period; executing setting processing that includes setting, as a video output range, a range containing both of the path of the ball and a path of the at least one player; and executing generation processing that includes generating video for the range set by the setting processing.
