Abstract: In this paper, advanced computer vision technology, image processing methods, and serial communication technology to instantly read out the readings of the reference force measuring instrument and the computer display force values of the CCD lens, solving the problem of different information between the force value display system of the material testing machine and the standard sensor display system. It ensures the correct information collection and accurate data processing during force value measurement, thus achieving high-speed, automatic accurate measurement.
Key words: testing machine for materials; force magnitude; industrial cameras; automatic acquisition and processing
