| Abstract: | The miss distance measurement error due to the rotation of the CCD sensor imaging surface in a video measurement system is analyzed with some relative mathematical models established, and the variation of this kind of error is discussed for different rotation angles of the imaging surface. How this measurement error can be checked and corrected are briefly discussed. Actual inspection shows the ways mentioned above can correct the miss distance measurement error resulting the rotation of the CCD sensor imaging surface and improve the accuracy of miss distance measurement, and it is suitable for an IR video measurement system. |
