| Abstract: | This paper is about the water-level auto reading based on image processing. Processing steps and method are introduced, which include image segmentation, water level line positioning, tick mark detection and calculation of water level. Edge detection, mathematical morphology and weighted image projector method were used in the tick mark detection. At the same time, the image processing combined with Laser water Level gauge was used for calculating the water level. The experiment proved that the method is feasible, and the result accuracy is 0.5 mm. |
