A new method for water level measurement method and its verification results are described. In this method, water surface in motion can be detected by temporal variation of pixel arrangement in successive digital images including the boundary between the staff gauge and the water surface. Laboratory and field tests were conducted for the two cases in which the staff gauge was contaminated by dirt or transparent due to clear water. The result shows water level can be accurately measure by this method for these two cases. It is expected that the accuracy of previous image stage gauge will be improved by the new method. |
