| Abstract: | In the applicattons of locating measurement, using traditional method, the CCD camera's resolution is limited by the sense element's physical dimension. In this paper, a method that improves CCD camera's locating accuracy is studied. This method does not require changes of the CCD array's physical characteristics.The error model of this method is analyzed and some strategies are proposed to reduce the influence of the stochastic error and discretion arror .A case study is presented .It is proved that this method can improve the accuracy of the CCD camera's locating measurement greatly. |
