| 摘 要： | 为了解决用扫描仪测量微生物抑菌圈直径时误差较大问题,对扫描仪误差进行了分析。扫描仪误差包括像素间距误差、像素间距横纵比误差及扫描起点误差等。提出用椭圆拟合法对扫描仪误差进行测量。通过V isual C++6.0编程,研究了扫描仪误差与扫描时间、扫描位置、扫描分辨力等因素的关系,发现了一些规律,为编程实现针对扫描条件的测量结果自动修正打下了基础。

| Abstract: | To reduce the measurement error of microbe bacteriostatic rings diameter,errors of scanner are analyzed.Scanner errors include pixel interval error,horizontal-to-vertical proportion error and starting position error.Ellipse curve fitting is used to determine these errors.Relations between error and scanning conditions such as scanned time,object position and scanning resolution are studied by Visual C++6.0 programming,which make possible of auto result correction according to scanning conditions. |

| Keywords: | scanner pixel interval error horizontal-to-vertical proportion error starting position error |
