摘要
To promote the accuracy and degree of automation in the process of oil measuring, an automatic detection system based on machine vision has been established. In this system, CCD camera is treated as a sensor and it collects image of oil level of the measurement cylinder. After image preprocessing, we improve the Canny margin extraction to achieve a better effect on margin detection. And then we use least-squares fitting to detect the sub-pixels margin line of the image. Finally, we calculate the oil volume.
