视觉测量装置的要求是可以测量两个测量值及其不确定度,本文开发了不确定性分析包括图像定位误差和成像变换的不确定性.(A requirement of a visual measurement device isthat both measurements and their uncertainties can be determined. This paper develops an uncertainty analysis which includes both the errors in image localization and the uncertainty in the imaging transformation.)
