In order to meet the requirements of the form and position accuracy measurement and the deformation control in the assembly process of launch vehicle structure cabin， the accurate and efficient measurement technology for super-large cabin is studied. First， the advantages and disadvantages of different measurement technology schemes are compared and analyzed. Second， based on the photogrammetry technology principle， the process of photogrammetry for super-large cabin is established. With the process， the point cloud data are collected， and the product model is reconstructed based on the collected point cloud data. Third， software is developed for the data alignment and comparison， with which the product form and position accuracy measurement and the assembly deformation analysis are realized. Finally， the feasibility of the photogrammetry method is verified by an example of a super-large riveted cabin.
