AI Technical Summary
In existing technologies, it is difficult to manually read water level scales under extreme weather conditions, which makes water level measurement inconvenient, and it is difficult to accurately obtain water level readings when the water level line and the scale are not aligned.
Image processing techniques are employed, including acquiring images of the water level scale, preprocessing, edge detection, cropping the water level scale lines, image binarization, and clustering algorithms, to obtain the parameters of the water level scale lines. The water level scale values are then estimated using formulas, and an error function is introduced to correct the configuration constant.
It enables automatic, efficient, and accurate acquisition of water level scale under extreme conditions, adapts to situations where the water level line and the scale are not aligned, and improves the automation and accuracy of water level measurement.
