Abstract :
This paper introduces a new system of liquid level measurement for standard metal tanks. In this system, the adoption of improved Sobel operator in its edge detecting algorithm and sub-pixel polynomial interpolation algorithm in its edge positioning has guaranteed high accuracy, robustness, invariance, and realized real-time on-line measurement.
