In this system, the movement of the step - electromotor is controlled by computer, and then the dial pointer is drove by the step - electromotor. at the same time, these images of the analog instrument are took by high precision ccd video, and then these images will be processed by the computer, using some image - processing algorithms such as image segmentations, threshold identification, image binarization, areas labeling, dial center - point identification, useful areas identification & abstracting, and areas thinning, etc. followed this, the dial pointer of the “ circle ” is able to be located. at last, the dial pointer position will be recognized by the computer
本系統由計算機控制步進電動機的運動,進而驅動指針式儀表表針的運動,並且通過高精度ccd攝像機實時獲取表盤圖像數據,同時進行表盤圖像的相關處理,包括圖像分割,閾值確定,圖像二值化,區域標記演算法,圓心擬合,有效區域識別提取,區域細化等,最終快速識別出表盤指針所處位置;最後,根據國家指針式儀表類檢定規程所制定的演算法計算出該儀表的相關誤差,檢定指針式儀表的各種精度,通過這些數據判斷該儀表是否合格,列印該儀表的檢定結果報表。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
本系統由計算機控制步進電動機的運動,進而驅動指示表表針的運動,通過高精度ccd攝像機實時獲取表盤圖像數據,同時進行表盤圖像的相關處理,包括閾值分割、邊緣檢測、圖像銳化以及區域分割和定心圓檢測等,最終快速識別出表盤指針所處位置,最後根據國家指示表類檢定規程所制定的演算法檢定出指示表的各種精度,本系統所採用的圖像處理演算法運算量少,速度快,從而大大提高了系統的實時性。According to the work principle, mechanical model theory and simulation analysis of the hydraulic control valve of the drilling tool, the optimal design parameters of the angle of center of circle of the high pressure hole of upside valve are proposed ; the influence of the charging and discharging lag times on palm supporting capacity is discussed ; and the theoretic basis of designing the control valve of the drilling tool is put forward in the paper
