According to the requirement of practical engineering application on the curved surface area information,inspired by the idea of CT tomography,a new method to calculate the curved surface area by utilizing the boundary information of every cross section is proposed.For the area of ellipsoid surface,conical surface and spherical surface,the numerical calculation results coincident with the theoretical results are presented.And then for the curved surface area of an egg,the boundary shape of every cross section was obtained with thin copper wires around the egg and was imaged.The boundary′s data of every cross section was extracted with the edge detection technique.The curved surface area of egg is calculated with Helen formula.Experiment results show that the method is practical,simple and precise,and can satisfy the needs of practical engineering application.
