Examples
- Grindability is determined by comparing the results of the screening analysis of the material sample to the calibration line
通过把对磨后的样品的筛析结果和校验直线相比较来确定该物料能否被碾磨。 - The calibration line is determined by using one set , i . e . 4 standard reference material samples with a different " hardgrove - index " of approx
校验直线按照样品的40 60 80 110h这四个标准的hardgrove指数来制定。 - The computer acquires the image of dial gauge by high precision ccd video , after that the computer will process the dial gauge image by some image - processing algorithms such as image segmentations , edge searching , area segmentations and locating the pointer by the " circle " . at last the computer will recognise the dial pointer position and work out the precision of dial gauge in accordance with nation criterion of dial gauge . this study presents several optimum algorithms to realize quick recognition of the pointer and calibration lines of detected dial and improve the accuracy and real time quality of detecting
本系统由计算机控制步进电动机的运动，进而驱动指示表表针的运动，通过高精度ccd摄像机实时获取表盘图像数据，同时进行表盘图像的相关处理，包括阈值分割、边缘检测、图像锐化以及区域分割和定心圆检测等，最终快速识别出表盘指针所处位置，最后根据国家指示表类检定规程所制定的算法检定出指示表的各种精度，本系统所采用的图像处理算法运算量少，速度快，从而大大提高了系统的实时性。 - The study on the auto - detecting system of analog measuring instruments presents several optimum algorithms to realize the quick recognition of the dial pointer and calibration lines of detected dial . by using these efficiency algorithms , both the accuracy and the real - time quality have been improved
采用数字图像处理技术进行指针式仪表的精度检定可以大大提高检定效率,提高检定精度,减少人为因素干扰,使检定过程更具客观性,检定结果更准确,因此具有广泛的市场前景。
