BufferedImage TYPE_INT_RGB与Mat不兼容？

-1

我有一个程序，我试图捕捉视频，我可以得到它的工作。我得到的程序工作，但不是我想要的方式，我想要一个RGB滤镜而不是BRG滤镜。BufferedImage TYPE_INT_RGB与Mat不兼容？

byte [] dat; 
if (dat == null || dat.length != w * h * 3) 
     dat = new byte [w * h * 3]; 
    if (img == null || img.getWidth() != w || img.getHeight() != h || img.getType() != BufferedImage.TYPE_3BYTE_BGR) 
     img = new BufferedImage(w, h, BufferedImage.TYPE_3BYTE_BGR);

相机加载但我想要一个RGB过滤器。这是我试图让我的RGB过滤器，所以我改变了我的代码。

import org.opencv.core.Core; 
import org.opencv.core.Mat; 

public class Mat2Image { 
    Mat mat = new Mat(); 
    BufferedImage img; 
    int[] dat; 

    Mat2Image(){ 
    } 

    public Mat2Image(Mat mat) { 
     getSpace(mat); 
    } 

    public void getSpace(Mat mat) { 
     this.mat = mat; 
     int w = mat.cols(), h = mat.rows(); 
     if (dat == null || dat.length != w * h) 
      dat = new int[w * h]; 
     if (img == null || img.getWidth() != w || img.getHeight() != h || img.getType() != BufferedImage.TYPE_INT_RGB) 
      img = new BufferedImage(w, h, BufferedImage.TYPE_INT_RGB); 
    } 

    BufferedImage getImage(Mat mat) { 
     getSpace(mat); 
     mat.get(0, 0, dat); 
     img.getRaster().setDataElements(0, 0, mat.cols(), mat.rows(), dat); 
     return img; 
    } 
    static { 
     System.loadLibrary(Core.NATIVE_LIBRARY_NAME); 
    } 
}

当我运行程序时，它会引发异常。

我不知道这是什么意思或是什么原因造成的。

你能发布完整的堆栈跟踪吗？ – mcarlin

我将它添加到帖子@mcarlin – cuber

“我得到了程序工作”：你全部设置！ – gpasch

堆栈跟踪告诉你实例化的Mat对象的类型不支持使用int []作为数据类型的get（）调用。如果您在1034行查看the source code，那就是您要调用的方法。它期望您的Mat对象的类型字段为CvType.CV_32S。我对OpenCV并不熟悉，但是您可以尝试在构造函数中将Mat对象与CvType.CV_32S作为类型参数进行实例化，并查看是否可以解决您的问题。
