Method of Measuring Statistical Tracking Ratio Error of Photoelectric Tracking Positioning Systems

The space coordinates of a dynamical target are fixed by the photoelectric tracking positioning system, captured by a computer and then compared with the real ones of the dynamical target to get the error. The theory of measuring statistical tracking ratio error of a photoelectric tracking system is analyzed and the implement for measuring is presented. Dynamical target is made by the aid of a source developed by ourselves. The error curve of statistical tracking ratio of a low light level TV tracking positioning system is obtained. The measurement of statistical tracking system is achieved by using the implement and the method and the error curve obtained is in accord with the theory.
