VP引导定位软件-旋转标定

一 确定通讯协议

Rotate,Angle,第几个点 Rotate,-20,1Rotate,-10,2Rotate,0,3Rotate,10,4Rotate,20,5

二 解析上位机数据

elseif(GlobalParameters.SoftModel=="Rotate"){// 如果是第一个点，则清空之前的数据if(Convert.ToInt32(msg.Split(',')[2])==1){// AlgorithmService.Instance.ClearRotateCali();}}

三 算法实现

/// <summary>/// 旋转点坐标/// </summary>publicList<Double>ImageX_Rotate_List=newList<Double>();publicList<Double>ImageY_Rotate_List=newList<Double>();

/// <summary>/// 添加旋转标定的点/// </summary>/// <param name="imageX"></param>/// <param name="imageY"></param>publicvoidAppendCirclePoint(doubleimageX,doubleimageY){ImageX_Rotate_List.Append(imageX);ImageY_Rotate_List.Append(imageY);}

/// <summary>/// 生成旋转中心标定/// </summary>publicvoidGenRotateCalibrationFile(outDoubleCenterX,outDoubleCenterY){if(ImageX_Rotate_List.Count==5){CenterX=0;CenterY=0;MessageBox.Show("生成旋转中心成功！");}else{CenterX=0;CenterY=0;}}
