【Task】 In athletic competitions involving jumping such as figure skating, there is a need to measure the jump height and flight distance by accurately calculating the trajectory of a moving object from a moving image captured by a simple monocular camera. SOLUTION: The present invention detects a specific point of a target moving object from the information of the image frame, calculates the amount of change regarding the three-dimensional position of the specific point from the information of a plurality of continuous image frames, and passes through the takeoff point and the landing point. A goal to jump from the information of multiple image frames captured by a monocular camera, which is characterized by calculating the three-dimensional trajectory of a specific point from the positional relationship between a curve that can describe a parabolic motion and a straight line where a specific point exists. Provided are a device, a method, and a program for calculating a three-dimensional trajectory of a moving object. [Selection diagram] Fig. 1
