WebFeb 26, 2024 · Abstract: The measurement of non-full pipe uniform flow with circular section is the focus of energy saving and emission reduction and government regulation. In order to study the accurate measurement of non-full flow, a three- dimensional mathematical model was established, and the boundary conditions were determined. Roundness is the measure of how closely the shape of an object approaches that of a mathematically perfect circle. Roundness applies in two dimensions, such as the cross sectional circles along a cylindrical object such as a shaft or a cylindrical roller for a bearing. In geometric dimensioning and tolerancing, control of a cylinder can also include its fidelity to the longitudinal axis, yielding cylindricity. The analogue of roundness in three dimensions (that is, for spheres) is s…
WebCircular fringe Fourier transform profilometry (CFFTP) based on a triangulation system has the capability of whole out-of-plane measurement using fewer fringes. To the best of our knowledge, the existing CFFTP [ 25, 26] calculates the displacement amount carrying the height information of the object by solving a quadratic equation.
