    Abstract: As an important geometric feature,the uncertainty of polygon is the extension and the depth of line uncertainty. As for this problem,the uncertainty estimation of three-dimensional polygon is studied here,and based on the confidence domain model of line,the uncertainty of three-dimensional polygon is described and estimated from two aspects of the model and the measurement of confidence domain.And then,The acceptance specification for urban construction is chosen to prove that the research of this article is correct.Several conclusions can be got as follows:①The uncertainty model of three-dimensional polygon is proposed here,referring to the derivation of line.②The uncertainty model of three-dimensional polygon is estimated based on integral calculus.③The uncertainty estimation model of three-dimensional polygon can be used to control quality in the field of engineering.
