三、 用預(yù)處理工具? 加減常數(shù)，讓圖片變得更亮點(diǎn)

四、圓展開工具

?

五、模板匹配

六、代碼分解

1.創(chuàng)建集合和文子顯示工具

CogGraphicCollection dt = new CogGraphicCollection();CogGraphicLabel Label;

2.加載工具，并實(shí)例化一個List集合

 dt.Clear();CogPolarUnwrapTool polar = mToolBlock.Tools["CogPolarUnwrapTool1"]as CogPolarUnwrapTool;CogPMAlignTool pma = mToolBlock.Tools["CogPMAlignTool1"]as CogPMAlignTool;List<double> listX = new List<double>();

3.定義圖標(biāo)中的坐標(biāo)嗎，添加集合，排序

 double total = 0;double x, y;for(int i = 0;i < pma.Results.Count;i++){listX.Add(pma.Results[i].GetPose().TranslationX);total += pma.Results[i].GetPose().TranslationY;}y = total / pma.Results.Count;listX.Sort();

4.進(jìn)行傳參，找出之前的x和y坐標(biāo)系，并用參數(shù)接收是否存在缺失

int a = 0;for(int i = 0;i < listX.Count - 1;i++){if((listX[i + 1] - listX[i]) > 50){x = (listX[i + 1] + listX[i]) / 2;y = total / pma.Results.Count;double lastx,lasty;polar.RunParams.GetInputPointFromOutputPoint(polar.InputImage, polar.Region, x, y, out lastx, out lasty);dt.Add(Create(lastx, lasty));a++;}}

5.進(jìn)行判斷是否缺失

 Label = new CogGraphicLabel();if(a > 0){Label.SetXYText(100, 100, "缺失"+a);Label.Color = CogColorConstants.Red;Label.Font = new Font("楷體", 30);dt.Add(Label);}else{Label.SetXYText(100, 100, "OK");Label.Color = CogColorConstants.Green;Label.Font = new Font("楷體", 30);dt.Add(Label);}

6.將上面?zhèn)魅雸A展開的x，y坐標(biāo)，進(jìn)行創(chuàng)建圓

private CogCircle Create(double x, double y){CogCircle co = new CogCircle();co.CenterX = x;co.CenterY = y;co.Radius = 20;co.LineWidthInScreenPixels = 6;co.Color = CogColorConstants.Red;dt.Add(co);return co;}

7.輸出

for(int i = 0;i < dt.Count;i++){mToolBlock.AddGraphicToRunRecord(dt[i], lastRecord, "CogIPOneImageTool1.InputImage", "");}

七、polar.RunParams.GetInputPointFromOutputPoint

該方法用于輸出圖像中的坐標(biāo)?(x, y)?轉(zhuǎn)換為輸入圖像中的坐標(biāo)?(lastx, lasty)

• polar.InputImage?是輸入圖像對象
• polar.Region?可能是指定的處理區(qū)域
• x, y?是輸出圖像中的坐標(biāo)
• out lastx, out lasty?是輸出參數(shù)，表示轉(zhuǎn)換后的輸入圖像中的坐標(biāo)。

???????polar.RunParams.GetInputPointFromOutputPoint(

1. polar.InputImage, // 輸入圖像

2. polar.Region, // 處理區(qū)域

3. x, // 輸出圖像中的X坐標(biāo)

4. y, // 輸出圖像中的Y坐標(biāo)

5. out lastx, // 輸出：對應(yīng)的輸入圖像中的X坐標(biāo)

6. out lasty // 輸出：對應(yīng)的輸入圖像中的Y坐標(biāo) );

???????注意事項(xiàng)：

1. 方法的作用：該方法的主要作用是將輸出圖像中的坐標(biāo)映射回輸入圖像中的坐標(biāo)，通常用于圖像變換后的逆向坐標(biāo)查找。
2. 參數(shù)檢查：確保?polar.InputImage?和?polar.Region?已正確初始化，并且?x, y?坐標(biāo)在有效的范圍內(nèi)。
3. 返回值：lastx?和?lasty?是通過?out?參數(shù)返回的，因此調(diào)用后可以直接使用這兩個變量獲取轉(zhuǎn)換后的坐標(biāo)。
