Abstract:
The principles of image monitoring system for bridge's deformation is proposed. Based on linear system theory, the whole system comprises linear shift-invariant system composed of atmosphere, optical sub-system and camera. The modulation transfer function of each component is analyzed, especially for the atmosphere. For a special system, modulation transfer functions on different weather condition such as sunny, cloudy, rainy and fogy weather are analyzed.
