calibration line中文什么意思
例句與用法
- Grindability is determined by comparing the results of the screening analysis of the material sample to the calibration line
通過把對(duì)磨后的樣品的篩析結(jié)果和校驗(yàn)直線相比較來確定該物料能否被碾磨。 - The calibration line is determined by using one set , i . e . 4 standard reference material samples with a different " hardgrove - index " of approx
校驗(yàn)直線按照樣品的40 60 80 110h這四個(gè)標(biāo)準(zhǔn)的hardgrove指數(shù)來制定。 - 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
本系統(tǒng)由計(jì)算機(jī)控制步進(jìn)電動(dòng)機(jī)的運(yùn)動(dòng)，進(jìn)而驅(qū)動(dòng)指示表表針的運(yùn)動(dòng)，通過高精度ccd攝像機(jī)實(shí)時(shí)獲取表盤圖像數(shù)據(jù)，同時(shí)進(jìn)行表盤圖像的相關(guān)處理，包括閾值分割、邊緣檢測(cè)、圖像銳化以及區(qū)域分割和定心圓檢測(cè)等，最終快速識(shí)別出表盤指針?biāo)幬恢?，最后根?jù)國(guó)家指示表類檢定規(guī)程所制定的算法檢定出指示表的各種精度，本系統(tǒng)所采用的圖像處理算法運(yùn)算量少，速度快，從而大大提高了系統(tǒng)的實(shí)時(shí)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
采用數(shù)字圖像處理技術(shù)進(jìn)行指針式儀表的精度檢定可以大大提高檢定效率,提高檢定精度,減少人為因素干擾,使檢定過程更具客觀性,檢定結(jié)果更準(zhǔn)確,因此具有廣泛的市場(chǎng)前景。
