摘要：
The present invention discloses an analysis method for a regional image. The analysis method relates analysis for an image data from a C-arm device. The analysis method includes following steps: providing an indication module, reading the image data, selecting a plurality of ROI (Region of Interest), calculating an average brightness of each ROI, searching every steel ball image data, comparing each steel ball image data and analyzing each steel ball image data. By individually analyzing each regional image data, the brighter or darker image signal can be excluded so that it can improve precision during searching the steel ball image data. Moreover, it is also more effective for comparing an image profile of the steel ball image data with a real profile of the steel ball of the indication module. Thus, the steel ball image can be readily defined by its correspondence with the steel ball of the indication module.本發明係為一種影像之區域分析方法,執行於C型臂影像擷取裝置,用於分析C型臂影像擷取裝置所擷取之影像資料,其包括下列步驟:提供標記模組;讀取影像資料;於影像資料中選取複數個注意區域;計算每一注意區域之平均亮度;搜尋每一鋼珠影像資料;比對每一鋼珠影像資料;以及分析每一鋼珠影像資料。藉由個別分析每一區域中的影像資料,用以避免因為影像資料中過亮或過暗之影像訊號而影響了搜尋鋼珠影像資料時的準確度,進而便於比對鋼珠影像資料之影像輪廓資料與標記模組中鋼珠之實際輪廓資料,藉以定義出鋼珠影像資料是否對應至標記模組之鋼珠。S100...影像之區域分析方法S10...提供一標記模組S20...讀取影像資料S30...影像資料中選取複數個注意區域S40...計算每一注意區域之一平均亮度S50...搜尋每一鋼珠影像資料S60...比對每一鋼珠影像資料S70...分析每一鋼珠影像資料
