ABSTRACT
In the 21st century, we are deeply impacted by global warming and extremely climate change. Meanwhile, relative organizations around the world carry out disaster prevention research. Since along with the tendency to enhance disaster occurred, the number of relevant monitoring system is used along with the growth of the field of disaster prevention. However, there are several limitations in the system of conventional monitors. For example the traditional monitor system usually needs people to keep an eye on those disasters, which makes the changes of disasters cannot be passed instantly and correctly. This paper will propose a set of image algorithms for disaster analysis detection technology. Through the non-contact measurement mode, analyze information of rivers in Taiwan and extract crucial information of river surface velocity in hydrological disaster prevention. With driftwood in rivers, bubble waves, swirling waves and other changes of images, using Retinex theory and correlation with related technical principles of the application, it will overcome the interference effect of light and shadows in harsh environments. This mode can also correctly estimate instantaneous surface velocity of the river, and through experiment of several images information to verify the river surface velocity by the instrument in the same time, confirmed the development of this system has its value and reliability. It is expected to achieve effectiveness of real time information detection and automatic notification system of disaster prevention.
