java - cvtColor 崩溃 android

转载作者：行者123 更新时间：2023-12-02 12:10:46

我一直在尝试进入 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;
   }

我无法解释为什么在视频运行 10 秒后 Android 应用程序不断崩溃，没有 cvtColor 它运行得很好。

想知道这里会发生什么。

-> 0)

看起来相机缓冲区在某个时刻消失了，认为这就是日志中发生的情况。

谢谢

最佳答案

似乎问题出在

Mat gray = new Mat();

line，因为它会在每个新相机帧上创建新的Mat。尝试将 Gray 变量设置为全局变量，并在 onCameraViewStarted() 中创建一次，然后将其用作 Imgproc.cvtColor() 参数。类似这样的事情:

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;
    }

    ...

}
