An Innovative Multi-headed Camera Network: A Displacement-Relay Videometrics Method in Unstable Areas

The subsidence of ground beds occurs frequently in large construction projects such as bridges, dams, high buildings and railways, which may cause damage and sometimes create disasters. Especially along with the establishment and the development of the high-speed railway, tiny subsidence and deformation of the railway beds will result in the decline in the service quality and safety. Therefore, automatic and long-duration subsidence surveillance is becoming increasingly important.
