Asked 2 years, 2 months ago Modified 1 year, 2 months ago Viewed 3k times 0 How can I convert a point cloud saved in rosbag, in format sensor_msgs/PointCloud2, to .bin files in KITTI format? I know that it is possible to convert to .pcd (http://wiki.ros.org/pcl_ros#point...
pcl::toROSMsg pcl::fromROSMsg convertPointCloudToPointCloud2 convertPointCloud2ToPointCloud 1.pcl_conversions::fromPCL 作用: 将pcl::PCLPointCloud2类型转换为sensor_msgs::PointCloud2类型。 使用场景: 当你在 PCL (Point Cloud Library) 中处理点云数据并需要将其转换为 ROS 消息格式 (sensor_msgs::P...
有时候需要把ros中PointCloud2格式的点云保存成本地ply文件来进一步分析。 整理一个python脚本来完成此任务: 1. 核心脚本 bag_pointcloud_to_plys.py 改编自如下链接的保存图像的脚本 https://gist.github.com/wngreene/835cda68ddd9c5416defce876a4d7dd9: ...
把PCL 第一代 PointCloud 转为 ROS PointCloud2,用于发布 ROS 的点云主题: void pcl::toROSMsg(const pcl::PointCloud<T> &, sensor_msgs::PointCloud2 &); 比如: // PCL 第一代点云 pcl::PointCloud<pcl::PointXYZRGB>::Ptr out_cloud(new pcl::PointCloud<pcl::PointXYZRGB>); ...
