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秒后不断崩溃Android应用程序，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些时候消失了，想想那是从日志中发生的事情。
谢谢
似乎问题在于
Mat gray = new Mat();
因为它在每个新相机框架上创建新的Mat。尝试使gray变量全局并在onCameraViewStarted()中创建一次，并使用Imgproc.cvtColor()参数。像这样的东西：
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;
}
...
}
