The size of the image is stored in the Width and Height properties. This is my code: pcl::PCLPointCloud2 cloud_inliers_pcl2; pcl::toPCLPointCloud2 (cloud_inliers, cloud_inliers_pcl2); But the pcl::PCLPointCloud2 returns empty fields. Coherent 4D imaging technology for uncompromising performance. ROS sends the actual image data using a vector in the Data property. For each point, you find the r,g,b values. Point clouds organized as 2d images may be produced by# camera depth sensors such as stereo or time-of-flight. Click on the `By topic` tab. There is a function to convert from one to another, but the documentation is very poor. Ready to optimize your JavaScript with Rust? Some points are removed from the point cloud with these parameters: referenceVector - Normal to the ground plane. Thanks for the answer, but for example in the "read PCD" tutorial of the PointCloud I read: "Alternatively, you can read a PCLPointCloud2 blob (available only in PCL 1.x). Due to the dynamic nature of point clouds, we prefer to read them as binary blobs, and then convert to the actual representation that we want to use. ( min_points.)
