Research on the Precision Assessment of Images for Videogrammetry

Videogrammetry is a task-oriented and multi-stage metrology and its precision assessment which is influenced by many factors is the important and difficult point of research. In order to analyze and assess the configurations and stages, the simulation system for the optimization of videogrammetry is designed, which can provide network configurations, precision assessment, etc.. Moreover, the precision assessment of images is the basis of the 3D reconstruction point error estimation. A new method to assess the precision of images is proposed in this paper and the 2D standard conference plate is designed. In this new method, the influences of all factors are taken into account together and the interrelations can be ignored. So the precision assessment of images is simplified. With the experimental results, the feasibility of this method has been testified by the application of the simulation system in the measurement of gossamer inflatable antenna.
