我想并行化以下代码段，但我是 openmp 和创建并行代码的新手。

std::vector<DMatch> good_matches;
for (int i = 0; i < descriptors_A.rows; i++) {
   if (matches_RM[i].distance < 3 * min_dist) {
      good_matches.push_back(matches_RM[i]);
   }
}

我试过了

std::vector<DMatch> good_matches;
#pragma omp parallel for
for (int i = 0; i < descriptors_A.rows; i++) {
   if (matches_RM[i].distance < 3 * min_dist) {
      good_matches[i] = matches_RM[i];
   }
}

和

std::vector<DMatch> good_matches;
cv::DMatch temp;
#pragma omp parallel for
for (int i = 0; i < descriptors_A.rows; i++) {
   if (matches_RM[i].distance < 3 * min_dist) { …
