To obtain a coefficient of restitution (COR) of an impact between baseball and bat from a mesurement using high speed video camera, a computer program for automated image processing is developed. In this program, an original image is transferred to edge detected image and a background except bat and ball region is removed. Template matching technique is employed to identify the locations of bat and ball. The value of COR is calculated from velocities of bat and ball which are derived from sequential location data. The automated image processing using the developed program is performed for several impact experiments. These results are compared with results obtained by manual image processing of the identical images and numerical analysis results by the finite element method. From this comparison, high accuracy and validity of the developed program are verified.
