摘要: The availability of a suitable data acquisition sensor network is key implementation issue to link models with real world structures. Non-contact displacement sensors should be preferred since they do not change the system properties. A two-dimensional vision-based measurement focus this contribution. In particular, perspective distortion introduced by angle between optic axis camera and normal plane in which structural deforms considered. affine transformation utilized eliminate from recorded distortion-free image. results laboratory experiment show potential proposed approach.
