The purpose of this study was to develop a calculation method of camera parameters using feature points on the field. The camera-parameter calculation (CC) method used in this study was as follows. Three-dimensional coordinates of three control points on the runway of the javelin throw were obtained and digitized. Digitizer coordinates of the control points were calculated with a set of camera parameters (focal length, lens location, Euler angles to transform from the global coordinate system to the digitizer coordinate system, and digitizer coordinates of the optical center). Reprojective error was estimated as the difference between the digitized and calculated coordinates of the control points. Camera parameters were computed with a genetic algorithm to minimize reprojective error. Three-dimensional coordinates of eight vertices of a 4.0 m × 8.0 m × 2.5 m control volume were computed and standard errors were compared between the CC method and a conventional static calibration (SC) method. There was no remarkable difference in the standard errors of the eight vertices calculated with the CC method (0.005 m) and the SC method (0.005 m), indicating that the CC method allows for accurate collection of three-dimensional coordinates using only three control points, as opposed to the six non-coplanar control points required by the SC method.
