Abstract

The expression system of uncertainty in conventional scale has been perfect, however, due to varies of error sources, it is still hard to obtain the uncertainty of large-scale instruments by common methods. In this paper, the uncertainty is evaluated by Monte Carlo simulation. The point-clouds created by this method are shown through computer visualization and point by point analysis is made. Thus, in fusion measurement, apart from the uncertainty of every instrument being expressed directly, the contribution every error source making for the whole uncertainty becomes easy to calculate. Finally, the application of this method in measuring tunnel component is given.
