    Due to the increasing complexity of earthquake engineering experiments, traditional sensors are becoming insufficient for all requirements. In addition, the quantity of traditional sensors is commonly limited due to the complexity and cost of sensor instrumentation. In automobile industry, high-speed digital video cameras have been employed to measure high-speed impact, large displacement and extreme deformation in related experiments. However, similar technologies are rarely seen in earthquake engineering area. In 2004, a shake-table experiment at NCREE preliminarily employed digital video cameras and successfully captured large-displacement history in the tests. It shows the feasibility of large-displacement measurement using video image processing. Due to the continuously increasing technology and coming down cost, digital video recorders have potential to be employed for earthquake engineering experiment measurement. Videos or continuous Images can be used for displacement measurement, deformation monitoring, crack recognition or other earthquake engineering applications. ¡§ ImPro ¡¨ is a GUI program which is developed based on matlab, basic goal of ImPro is to study employ of the video processing and applications on earthquake engineering experiments. The main focus is on the 2D dynamic displacement measurement. There are still some problems need to be solved, such as target sheltered, target out of field, and displacement speed too fast.
