如何在检测图像中的形状时使用AForge.net解决c＃中的以下错误：“错误2参数'2'：无法从'AForge.IntPoint []'转换为'System.Drawing.PointF []'标记为whr胆大

本文介绍了如何在检测图像中的形状时使用AForge.net解决c＃中的以下错误：“错误2参数'2'：无法从'AForge.IntPoint []'转换为'System.Drawing.PointF []'标记为whr胆大的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述 位图图像=（位图）pictureBox4.Image; //创建blob计数器实例 BlobCounter blobCounter = new BlobCounter（）; blobCounter.FilterBlobs = true; blobCounter.MinHeight = 5; blobCounter.MinWidth = 5; //处理扩张的图像 blobCounter.ProcessImage（image）; //获取有关检测到的对象的信息 Blob [] blobs = blobCounter.GetObjectsInformation（）; //创建一个图形对象来绘制图像和一支笔 图形g = Graphics.FromImage（图像）; Pen Redpen =新笔（Color.Red，2）; SimpleShapeChecker shapechecker = new SimpleShapeChecker（）; //签入图片并在找到矩形的对象周围绘制 for（int i = 0，n = blobs.Length; i< n; i ++）> { List< intpoint> edgepoints = blobCounter.GetBlobsEdgePoints（blobs [i]）; List< intpoint>角点; if（shapechecker.IsQuadrilateral（edgepoints，out cornerpoints）） { if（shapechecker.CheckPolygonSubType（cornerpoints）== PolygonSubType .Rectangle） { g.DrawPolygon（Redpen， cornerpoints.ToArray（））; } b $ b } } Redpen.Dispose（）; g.Dispose （）; Bitmap image = (Bitmap)pictureBox4.Image; // create instance of blob counter BlobCounter blobCounter = new BlobCounter(); blobCounter.FilterBlobs = true; blobCounter.MinHeight = 5; blobCounter.MinWidth = 5; //process the dilated image blobCounter.ProcessImage(image); // get info about detected objects Blob[] blobs = blobCounter.GetObjectsInformation(); // create a graphics object to draw on the image and a pen Graphics g = Graphics.FromImage(image ); Pen Redpen = new Pen(Color.Red, 2); SimpleShapeChecker shapechecker= new SimpleShapeChecker (); //check in image and draw around the object found as rectangle for(int i=0,n=blobs.Length ;i<n;i++)> { List<intpoint> edgepoints = blobCounter.GetBlobsEdgePoints(blobs [i ]); List <intpoint> cornerpoints; if (shapechecker.IsQuadrilateral(edgepoints, out cornerpoints )) { if (shapechecker.CheckPolygonSubType (cornerpoints ) == PolygonSubType.Rectangle) { g.DrawPolygon (Redpen, cornerpoints.ToArray ()); } } } Redpen.Dispose(); g.Dispose();推荐答案 尝试如下，使用 System.Drawing.Point try as below, use System.Drawing.Point for(int i=0,n=blobs.Length ;i<n;i++)>{List<intpoint> edgepoints = blobCounter.GetBlobsEdgePoints(blobs [i ]);List<intpoint> cornerpoints;if (shapechecker.IsQuadrilateral(edgepoints, out cornerpoints )){if (shapechecker.CheckPolygonSubType (cornerpoints ) == PolygonSubType.Rectangle){g.DrawPolygon (Redpen, cornerpoints.Select(p => new System.Drawing.Point(p.X, p.Y)).ToArray());}}} 我已经尝试了谷歌上提供的所有可能的解决方案...就像我们的linq .. .which工作，然后关于要添加的代码，如从system.point转换为aforge，ad还有一件事我没有得到ToPointsArray方法......因为它不存在....我是错过了任何图书馆或参考资料....请帮助......我确定这是我错过的一件小事。很抱歉有问题，但我是新手使用Aforge.Net。I have tried all possible solutions available on google...like usin linq...which dint work , then about the code to be added like for conversion from system.point to aforge, ad one more thing i do not get the ToPointsArray method as well ...as in it does not exist ....am I missing out on any library or reference....please help....I'm sure its a small thing I'm missing out on. Sorry for the trouble but I'm new to using Aforge.Net . 这篇关于如何在检测图像中的形状时使用AForge.net解决c＃中的以下错误：“错误2参数'2'：无法从'AForge.IntPoint []'转换为'System.Drawing.PointF []'标记为whr胆大的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！
