多线程建议

我正在开发一个应用程序,主要目标是从图像采集器中获取图像,进行一些处理,然后在GUI上显示图像.帧抓取器连接到PCIe.我正在使用帧抓取器SDK.图像流非常慢10到100张图像/秒我在这里对我的代码以及如何优化它有一些建议.首先,我从一个继承自Qthread的类中获取run()函数,我抓取一个图像并将其放在缓冲区queuecv :: Mat>上.

void ImageIn::run(){
        _cam->allocMemory();
        _cam->startAquisition();
        _runningThread = true;

        while(_runningThread)
        {
             Mat image(_cam.getSizeX(), _cam.getSizeY(), CV_16U, _cam->getImageDMA0());

             _ctrl->getMutexIn()->lock(); // Lock BufferIn
             _ctrl->getBufferIn()->push(image); // store Image in BufferIn
             _ctrl->getMutexIn()->unlock(); // Unlock bufferIn
        }

}

图像存储在缓冲区中,然后处理线程做一些工作......

void ImageProcessing::run(){
while(_runningThread){
if (_ctrl->getMutexIn()->tryLock()){
    while(!_ctrl->getBufferIn()->empty()){
        _ctrl->getBufferIn()->front().convertTo(tempConvert, CV_32F);
        _bufferLocalIn.push(tempConvert);
        _ctrl->getBufferIn()->pop();
    }
    _ctrl->getMutexIn()->unlock();
}

// Do some processing and put image and a buffer for GUI
}
}

所以,我有一些问题: - 线程1由于阻塞功能而获得图像,因此CPU消耗很低,但线程2连续运行并消耗大量CPU重新评估我可以做些什么来修复它？ - 这是编码的正确方法吗？

所以我试过了:

QThread* thread = new QThread;
ImageWriter* worker = new ImageWriter();
worker->moveToThread(thread);

QTimer* timer = new QTimer();
int msec = 100;
timer->setInterval(msec);

QObject::connect(thread, SIGNAL(started()), worker, SLOT(process()));
QObject::connect(worker, SIGNAL(finished()), thread, SLOT(quit()));
QObject::connect(timer, SIGNAL(timeout()), thread, SLOT(start()));
timer->start();

好吗？
