Paper Abstract

The measuring cylinder calibration is entirely relied on manually reading data, which lead to high workload and poor repeatability. This research is to design an Automatic Measuring Cylinder Calibration System (AMCCS) based on digital image processing technology to finish the whole calibration process include titration of the measuring cylinder and generating calibration record. The Application of Blob analysis, template matching and optical character recognition (OCR) technology can acquire the image information of the scale and liquid level of the measuring cylinder in real time, feedback to the system, and complete the synchronous output of the record. The methodology used in this research is quantitative method where data obtained through 20 experienced engineers and AMCCS, the result shows that this system is promoted in speed, measurement repeatability, which is 35% and 33%.
