QT编写UWB定位显示轨迹上位机代码

以下是一个简单的QT界面,用于显示UWB定位的轨迹:
```c++
#include "mainwindow.h"
#include <QApplication>
#include <QSerialPort>
#include <QSerialPortInfo>
#include <QDebug>
#define SERIAL_PORT_NAME "COM4" // UWB串口名称
#define SERIAL_PORT_BAUDRATE QSerialPort::Baud115200 // UWB串口波特率
// MainWindow类
class MainWindow : public QMainWindow
{
Q_OBJECT
public:
MainWindow(QWidget *parent = nullptr)
: QMainWindow(parent)
{
// 初始化串口
m_serialPort = new QSerialPort(SERIAL_PORT_NAME);
m_serialPort->setBaudRate(SERIAL_PORT_BAUDRATE);
m_serialPort->setDataBits(QSerialPort::Data8);
m_serialPort->setParity(QSerialPort::NoParity);
m_serialPort->setStopBits(QSerialPort::OneStop);
m_serialPort->setFlowControl(QSerialPort::NoFlowControl);
// 打开串口
if (!m_serialPort->open(QIODevice::ReadOnly)) {
qDebug() << "Failed to open serial port.";
return;
}
// 连接串口数据接收信号
connect(m_serialPort, &QSerialPort::readyRead, this, &MainWindow::readData);
// 初始化UI
m_canvas = new QLabel(this);
m_canvas->setPixmap(QPixmap(":/images/background.png"));
setCentralWidget(m_canvas);
setFixedSize(m_canvas->pixmap()->size());
}
~MainWindow()
{
// 关闭串口
m_serialPort->close();
delete m_serialPort;
}
private slots:
void readData()
{
// 读取串口数据
QByteArray data = m_serialPort->readAll();
// 解析数据
QList<QPointF> points;
for (int i = 0; i < data.size(); i += 12) {
QPointF point;
point.setX((data[i] << 8) | data[i + 1]);
point.setY((data[i + 2] << 8) | data[i + 3]);
points.append(point);
}
// 更新UI
QPixmap pixmap = m_canvas->pixmap()->copy();
QPainter painter(&pixmap);
painter.setPen(QPen(Qt::red, 2));
painter.drawPolyline(QPolygonF(points));
m_canvas->setPixmap(pixmap);
}
private:
QSerialPort *m_serialPort;
QLabel *m_canvas;
};
int main(int argc, char *argv[])
{
QApplication a(argc, argv);
MainWindow w;
w.show();
return a.exec();
}
```
这个代码使用了QT的serialport模块来读取UWB串口数据,并将数据解析为点集,最后在UI上绘制轨迹。请注意,这个代码仅提供了基础的UI和串口通信功能,你需要根据你的具体需求来进行修改。
