） Abstract： Two methods can be used to measure water level
One is creating a water-level measuring post, then read it by human each time
Another one is using sensor to derive the analog water level, then transform it to digital value
There are many different sensors for water level measuring, such as float model, pressure model, supersonic model, etc
This paper provides a method that derives the image of water level by camera firstly, then by employing the methodology of image preprocessing, we can get the number of the calibrations above the water, in the end conduct the water level value
Using this method, the devices are easily to install, can save cost, and has high precision, so it is suitable to apply in irrigation district
