Basler相机Bayer转RGB或BGR的黑边问题

针对右侧和下侧黑边问题,对官方转换函数设置如下即可解决:

相机像素格式:BayerRG8

【C++】

CImageFormatConverter fc;
fc.OutputPixelFormat = PixelType_BGR8packed;  //用于OpenCV
//fc.OutputPixelFormat = PixelType_RGB8packed;  //用于Halcon  
//fc.InconvertibleEdgeHandling = InconvertibleEdgeHandling_SetZero;   //默认右、下边缘补0
fc.InconvertibleEdgeHandling = InconvertibleEdgeHandling_Extend;  //推荐设置,否则右、下有黑边
CPylonImage image;
fc.Convert(image,ptrGrabResult); 
//转换为BGR后,赋给OpenCV
Mat cv_img = cv::Mat(ptrGrabResult->GetHeight(),ptrGrabResult->GetWidth(), CV_8UC3,(uint8_t*)image.GetBuffer() ) ;

【C#】参考SDK案例 GUI_SampleMultiCam

其中 PixelDataConverter converter = new PixelDataConverter();

Bitmap bitmap = new Bitmap(grabResult.Width, grabResult.Height, PixelFormat.Format24bppRgb);
// Lock the bits of the bitmap.
BitmapData bmpData = bitmap.LockBits(new Rectangle(0, 0, bitmap.Width, bitmap.Height), ImageLockMode.ReadWrite, bitmap.PixelFormat);
converter.OutputPixelFormat = PixelType.BGR8packed;                      
converter.Parameters[PLPixelDataConverter.InconvertibleEdgeHandling].SetValue("Extend");    //设置成Extend方式

// Place the pointer to the buffer of the bitmap.
IntPtr ptrBmp = bmpData.Scan0;
converter.Convert(ptrBmp, bmpData.Stride * bitmap.Height, grabResult);
bitmap.UnlockBits(bmpData);

//Windows和Basler两种存bitmap方式,效果一样
bitmap.Save("test.bmp", System.Drawing.Imaging.ImageFormat.Bmp);    //推荐存为bmp
ImagePersistence.Save(ImageFileFormat.Bmp, "sdk_test.bmp", grabResult);

bitmap.Save("test.jpg", System.Drawing.Imaging.ImageFormat.Jpeg);  //jpg是压缩后的格式,像素数据损失较大
ImagePersistence.Save(ImageFileFormat.Jpeg, "sdk_test.jpg", grabResult);

 

【非官方转换函数】

Mat bayerRG 转 Mat BGR

Mat cv_bayer_img = cv::Mat(ptrGrabResult->GetHeight(), ptrGrabResult->GetWidth(), CV_8UC1, (uint8_t*)ptrGrabResult->GetBuffer()); //相机的bayer像素赋给Mat bayer

之后直接使用此博客函数即可(虽然是BG2RGB但是也可用于RG转BGR) https://blog.csdn.net/zhoukehu_CSDN/article/details/126482534
