Abstract
In the athletic competition involving jumping such as figure skating, it is desired to measure jumping height and flight distance by calculating a trajectory of a moving object as a target from moving images captured by a monocular camera. Provided is a device, a method and a program to calculate the trajectory of the moving object jumping in three dimensions from information of a plurality of image frames captured by the monocular camera by detecting a specific point of the moving object, calculating an amount of change with respect to three-dimensional positions of the specific point in the consecutive image frames, and calculating the trajectory of the specific point from a positional relation between straight lines having the positions of the specific point and a curved line capable of expressing a parabolic motion passing through a take-off point and a landing point.
