cvtColor崩溃android

我一直试图进入OpenCV。下面的代码似乎在cvtColor上崩溃了。

    public Mat onCameraFrame(CvCameraViewFrame inputFrame) {
        mRgba = inputFrame.rgba();
        mGray = inputFrame.gray();

        Mat gray = new Mat();
        Imgproc.cvtColor(mRgba, gray, Imgproc.COLOR_RGB2GRAY);

        return gray;
   }

我无法理解为什么它在视频运行10秒后仍然会崩溃Android应用程序,而没有cvtColor它运行得很好。

想知道这里会发生什么。

看起来相机缓冲区在某个时刻消失了,想想那是从日志中发生的事情。

似乎问题在

Mat gray = new Mat();

一行,因为它会在每个新的相机框架上创建新的Mat。尝试将gray变量设为全局,并在onCameraViewStarted()中创建一次,并使用Imgproc.cvtColor()参数。这样的事情:

public class MainActivity extends AppCompatActivity implements CameraBridgeViewBase.CvCameraViewListener2 {
    private Mat mRgba;
    private Mat mGray;

    ...

    @Override
    public void onCameraViewStarted(int width, int height) {
        mGray = new Mat(height, width, CvType.CV_8U);
    }

    ...

    @Override
    public Mat onCameraFrame(CameraBridgeViewBase.CvCameraViewFrame inputFrame) {
        mRgba = inputFrame.rgba();
        Imgproc.cvtColor(mRgba, mGray, Imgproc.COLOR_RGB2GRAY);
        return mGray;
    }

    ...

}
