摘要
针对某专用瞄准经纬仪读数系统复杂、读数过程繁琐、读数精度受到诸多限制等突出问题 ,设计了一种能代替人眼进行瞄准读数或设备检定的计算机判读系统。系统运用了 Windows多线程、分割阈值自适应选取、矩心法图像细分、图像倾斜自动校正、连通域识别字符等多项技术 ,具有测量精度高、识别实时性好、自动化程度高等显著特点 ,在很大程度上发掘了该设备的应用潜力 。
In allusion to that some appropriative collimation theodolite is a complex system, which reading process is too troublesome, and its precision is limited, A kind of computer system instead of eyes to collimate is designed Because windows multithreading, threshold self adapting select, image subdivision, image incline auto revise and connected area disposal for image recognition are used, the system possess high precision, good real time characteristic, high automatization degree This system develops the application potential of the equipment at a large extent, and have well use for reference for other analogous system
