PCL Install on ROS2 1. Apt-based Installation sudo apt install libpcl* pcl-tools 2. Compling the build file from source PCL의 경우 버전마다 코드 상의 큰 변화가 있으므로 Source에서 일부 버전을 맞춰야하는 경우가 존재함. 따라서 PCL 공식 홈페이지에서 다운로드 후 빌드하여야 함. 필자의 경우 Ver 1.12 가 필요하여 다음의 Github에서 Tag에서 필요한 버전을 선택하였음. https://github.com/PointCloudLibrary/pcl GitHub - PointCloudLibrary/pcl: Point Cloud Library (PCL) Point Cloud Library (PCL).

ZED F9P with RTK - WGS to UTM Hello, we use ZED F9P with RTK corrections. Is it possible to retrieve (besides latitude and longitude) also UTM and other coordinates from the Ublox interface? I am grateful for any hint! Our RTK data stream provides a wealth of information, e.g. besides latitude, longitude and ellipsoidal heights also UTM coordinates, normal heights and coordinates referring to other coordinate systems. Is it .. 2021. 11. 9.
