The papers stated the technology of the computer control system which achieved in the four locomotives of new no . 1 and 2 coke oven in pangang . the following issues are the key of the papers : 1 . by using the long - distance precise position detection technology that coding cable and computer work together , to solve the problem of long - distance precise orientation in the four locomotives of new no . 1 and 2 coke oven automatic system in the company of pangangmeihua 论文对攀钢新1 、 2 #焦炉四大机车计算机控制系统的技术实现进行了阐述。重点讨论了以下几个问题: 1 、使用编码电缆与计算机配合的长距离精确位置检测技术,解决攀钢煤化工公司新1 、 2 #焦炉四大机车自动化系统的长距离精确定位难题。
Finally a novel algorithm flow is made to achieve 3d focusing with zoom microscope . for low enlargement images , global - coarse orientation is realized with auto - thresholding , corrosion - inflation operation and connected components labeling . and for large enlargement images , local - precise orientation is achieved by multiresolution wavelets segmentation on focus measure technique , which use the phenomena that images blur when out - of - focus 对于低放大倍数下的全局图像,主要利用形态学中的腐蚀膨胀操作、自动阈值分割、区域标记等技术完成了键合目标中心位置的粗定位;而对于高放大倍数下的局部图像,根据其半离焦的特征利用基于小波高频能量的多尺度显微图像分割方法实现了精定位。
Except that , many problem can " t be solved , such as the conflict of ccd " s high resolving power and big vision field , how to control the automatic gathering of pcb " s image using master and slave computer parallel structure , how to inspect the defect of pcb such as width of circuit , distance of circuit , losing circuit and so on . the research aim at how to combine computer vision , precise machine , automatic control with image process , at how to resolve the contradiction between high resolving power of image gathering and wide vision field , at how to realize automatic mosaic of image , at how to realize precise orientation of two dimension worktable , at how to realize communication between master computer and slave computer , and at how to inspect the defect of line width , line distance and losing 除此以外,还有ccd高分辨率和大视场之间的矛盾,上下位微机并行系统如何控制印刷电路板图像自动采集,印刷电路板的线宽、线距和丢失线条等缺陷如何检测等问题还悬而未决,本课题将就如何结合计算机视觉技术、精密机械技术、自动控制技术和图像处理技术,如何解决图像采集高分辨率与大视场之间的矛盾,如何实现图像的自动拼接,如何实现两维工作台的精确定位,如何实现上下位机的准确通讯,如何检测线宽、线距缺陷和丢失线条等问题展开重点研究。
