VisionPro拼接图像脚本实现代码

有时相机的视野不够大，或者不需要整个产品时，为了节省时间，我们会采取合并图像操作。将图像合并成一张图像进行处理，当然也可以分开处理。工业上拼接图像比较少见（可能是我没接触到），VisionPro提供了取像操作的预处理函数，我们可以在这里进行图像拼接。

VisionPro拼接图像脚本实现代码

上图是一张被均等分为4份的图像，拼接后如上图所示。拼接代码如下：

public override bool PostAcquisitionRefInfo(ref Cognex.VisionPro.ICogImage image,Cognex.VisionPro.ICogAcqInfo info){// To let the execution stop in this script when a debugger is attached, uncomment the following lines.// #if DEBUG// if (System.Diagnostics.Debugger.IsAttached) System.Diagnostics.Debugger.Break();// #endifCounter = Counter + 1;if(Counter == 1){//Create a new toolimageStitcher = new CogCopyRegionTool();//Create a destination image and assign it to the toolCogImage8Grey stitchedImage= new CogImage8Grey();stitchedImage.Allocate(image.Width * 2, image.Height * 2);imageStitcher.DestinationImage = stitchedImage;imageStitcher.Region = null;imageStitcher.RunParams.ImageAlignmentEnabled = true;//First sub-image goes into the upper left cornerimageStitcher.RunParams.DestinationImageAlignmentX = 0;imageStitcher.RunParams.DestinationImageAlignmentY = 0;}else if(Counter == 2){//Second sub-image goes into the upper right cornerimageStitcher.RunParams.DestinationImageAlignmentX = image.Width;imageStitcher.RunParams.DestinationImageAlignmentY = 0;}else if(Counter == 3){//Third sub-image goes into the lower left cornerimageStitcher.RunParams.DestinationImageAlignmentX = 0;imageStitcher.RunParams.DestinationImageAlignmentY = image.Height;}else{//Final sub-image goes into the lower right cornerimageStitcher.RunParams.DestinationImageAlignmentX = image.Width;imageStitcher.RunParams.DestinationImageAlignmentY = image.Height;}//Run the tool to add the just-acquired sub-imageimageStitcher.InputImage = CogImageConvert.GetIntensityImage(image,0,0,image.Width,image.Height);imageStitcher.Run();if(Counter == 4){//Set the acquired image to the final stitched imageimage = imageStitcher.OutputImage;//Reset to begin a new stitched image next timeimageStitcher = null;Counter = 0;//Return true to inspect the stitched imagereturn true;}else{//Return false to skip inspection and acquire the next sub-imagereturn false;}}

实现过程很简单，首先定义了总共需要拼接多少张图像，这里是4张。然后就创建了一个空白图像区域，长宽是一张图像的两倍，也就是四张图像大小。然后根据传递过来的图像顺序，分别放在固定位置，注意，图像坐标位置以左上角计算。

上面这段脚本在工作脚本中，不是工具组脚本！选择作业内容中顶部菜单栏的配置，打开作业属性，即可看见脚本入口。
