Aiming at the characteristics of large-scale, high-resolution, high-efficiency, complex structure of large component shape measurement in aerospace and marine manufacturing filed, a method for measuring the high-resolution geometric shape of large components was proposed, based on the optic-electrical scanning and positioning theory combined terminal shape measurement technology. The fringe projection photogrammetry system was used to project phase fringes on the local surface of the component to obtain high-precision dense point cloud, the pose measurement algorithm was designed to solve the problem that the pose measurement cannot be realized when the complex scene does not meet the intersection condition, the position of fringe projection photogrammetry system in the global measurement network system established by the workshop measurement positioning system(wMPS) can be measured. Therefore, the overall shape measurement of large components was completed through data fusion without relying on the software splicing algorithm. The experimental results show that the point cloud density of the system is 50 points/mm2, and the overall measurement accuracy of the system can reach 0.22 mm.
