WebMar 12, 2024 · Finally, we triangulate the corresponding pairs to obtain the local point cloud. Then local point clouds are merged into the global map along the points that belong to the same connected component, if the distance between two connected points lies within the threshold of 3.0m (hyperparameter). WebThe pose at camera n is calculated as follows is a 4×4 matrix. Given two poses the 2D image points can then be triangulated using cv::triangulatePoints. This function expects two projection matrices (3×4) as input. To make a projection matrix from the pose you also need the camera matrix K (3×3).
