2012-07-22 22:43:39 -0600 | asked a question | pcl::PointCloud to cv::Mat -> optimal way? Hi everybody! I would like to transform my point cloud 3D coordinates: to an OpenCV matrix: I could define a 3 channel float matrix with one row per point in the point cloud, like this: and then manually copy each point on the point cloud to the matrix. But, it feels like a little bit brute force approach. Can anyone suggest a more elegant way to do it? My ultimate goal is to apply OpenCV's k-means algorithm to extract clusters of points. Thanks in advance! |
