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

按照JJG 139—2014《拉力、压力和万能试验机》检定规程规定,在对塑料测试机进行检定时必须对其力值信息进行收集、计算、分析,结果必须直接反映隔振装置的检定结果与修正数据,作为本型号设备的主要技术参数之一。(剩余3776字)
