使用多线程加速处理这一段for循环vector<Edge1D_Result>edges;for (int i = 0; i < m; i++) { edges = Extract1DEdgeCircle.Get1DEdge(RoiMat, m_vpdEquinoxPoints[i], m_dMeasureLength, m_dMeasureHeight, m_vdMeasureAngle[i] , m_dSigma, m_nThresholdCircle, m_nTranslationCircle == 1 ? Translation::Poisitive : Translation::Negative, Selection::Strongest); for (int i = 0; i < edges.size(); i++) { m_vpdEdgePoints.push_back(edges[i].m_pdEdgePoint); m_vdEdgeGradient.push_back(edges[i].m_dGradient); } }保护变量edges

可以使用互斥锁mutex来保护变量edges。具体操作如下：

1. 在头文件中包含<mutex>。

2. 在for循环外定义一个mutex对象，例如：std::mutex mtx_edges。

3. 在for循环内对edges进行操作时，加锁mtx_edges，操作完成后解锁。

代码示例：

#include <mutex>

std::vector<Edge1D_Result> edges;
std::mutex mtx_edges;

for (int i = 0; i < m; i++) {
    edges = Extract1DEdgeCircle.Get1DEdge(RoiMat, m_vpdEquinoxPoints[i], m_dMeasureLength, m_dMeasureHeight, m_vdMeasureAngle[i], m_dSigma, m_nThresholdCircle, m_nTranslationCircle == 1 ? Translation::Poisitive : Translation::Negative, Selection::Strongest);
    // 加锁
    mtx_edges.lock();
    for (int j = 0; j < edges.size(); j++) {
        m_vpdEdgePoints.push_back(edges[j].m_pdEdgePoint);
        m_vdEdgeGradient.push_back(edges[j].m_dGradient);
    }
    // 解锁
    mtx_edges.unlock();
}
