我在本教程中添加了Crosswalk eclipse:ClickHere 我完成了教程中的所有操作并且没有错误,但是当我在手机上启动应用程序时,我有这样的:

我将带有外部dll的相机加载到我的OpenCV程序中.我可以看到框架 cv::imshow("edges", frame);,一切都很好.frame.channels()给了我3个频道,但是当我尝试cv::cvtColor(frame, gray, CV_BGR2GRAY);应用程序崩溃时.

CreateImage(System::Byte *imgData, int height, int width,int show)
{

    frame = cv::Mat(height, width, CV_8UC3, imgData);

    if (show > 0)
        cv::imshow("edges", frame); //I can see myself

    return frame.channels(); //three channels
}

void ConvertAndProcess()
{
    cv::Mat gray;

    cv::cvtColor(frame, gray, CV_BGR2GRAY); //crash...

    //do something
}

我已经挖了一段时间但没有结果.我究竟做错了什么？
