qt uuv图像传输代码示例

在Qt框架下，Unmanned Aerial Vehicles (UAVs) 的图像传输通常涉及到实时视频流处理。以下是一个简单的QTCreator项目中的基本代码示例，展示了如何使用Qt的Multimedia模块来实现实时图像从UUV（如无人机）到计算机的传输：

#include <QApplication>
#include <QVideoWidget>
#include <QTcpServer>

class ImageReceiver : public QObject
{
public:
    explicit ImageReceiver(QTcpServer *server)
        : server(server)
    {
        connect(server, &QTcpServer::newConnection,
                this, &ImageReceiver::newConnectionAccepted);
    }

private slots:
    void newConnectionAccepted()
    {
        QDataStream stream(connection());
        QImage image;
        if (stream.readNextVariant(&image)) {
            videoWidget->setPixmap(QPixmap::fromImage(image));
        } else {
            qDebug() << "Failed to receive image";
        }
    }

private:
    QTcpServer *server;
    QVideoWidget *videoWidget; // 创建一个QVideoWidget用于显示接收到的图像
};

int main(int argc, char *argv[])
{
    QApplication app(argc, argv);

    // 创建TCP服务器
    QTcpServer server;
    if (!server.listen("localhost", 8000)) {
        qCritical() << "Unable to start TCP server: " << server.errorString();
        return -1;
    }

    ImageReceiver receiver(&server);
    videoWidget = new QVideoWidget;
    videoWidget->show();

    return app.exec();
}
