Traditional valve manufacturers examine valve leakage by manual visual inspection, but this method is inefficient and prone to errors. Hence, this paper applies machine vision techniques to develop a measurement method that can detect valve leakage according to the global standards of the petroleum industry, such as those recommended by the American Petroleum Institute. A collection device and machine vision techniques were applied to count leaked bubbles. The results were then compared with traditional human visual counting. The proposed machine vision method can achieve a mean absolute error of less than 1% while also reducing two-thirds of the workload of traditional human visual counting. Experimental results confirmed the effectiveness of this method. This study is the first to adapt machine-vision technology to industrial valve leakage measurement and opens up new possibilities for further exploration of valve leakage. |
