问题 I have a code where I use the pcl/gpu namespace: pcl::gpu::Octree::PointCloud clusterCloud; clusterCloud.upload(cloud_filtered->points); pcl::gpu::Octree::Ptr octree_device (new pcl::gpu::Octree); octree_device->setCloud(clusterCloud); octree_device->build(); /*tree->setCloud (clusterCloud);*/ // Create the cluster extractor object for the planar model and set all the parameters std::vector<pcl::PointIndices> cluster_indices; pcl::gpu::EuclideanClusterExtraction ec; ec.setClusterTolerance (0

问题 I'm using ROS in my project and I need to send one message from time to time. I have this function: void RosNetwork::sendMessage(string msg, string channel) { _mtx.lock(); ros::Publisher chatter_pub = _n.advertise<std_msgs::String>(channel.c_str(),10); ros::Rate loop_rate(10); std_msgs::String msgToSend; msgToSend.data = msg.c_str(); chatter_pub.publish(msgToSend); loop_rate.sleep(); cout << "Message Sent" << endl; _mtx.unlock(); } And I have this in python: def callbackFirst(data): #rospy

问题 I am trying to perform a segmentation task with PCL/ROS. I am using the dynamic configuration option in ROS as the number of inputs to my segmentation task is large and would like to study the influence of each param . There is no problem with my C++ source code, however when I try to run the launch file my file publisher is not able to find the PCD files. <launch> <!-- Start segmentation analysis --> <node pkg="segmentation_analysis" name="region_growing" type="region_growing" output="screen

How to install Robot Operating System ROSJava on Windows?

由 蹲街弑〆低调 提交于 2019-12-12 22:01:05
问题 The documentation for ROS is terrible. One great irony is that the Groovy and ROSJava versions of ROS was created to allow developers on platforms like Windows to utilize the great robotics SDK, while all the installation instructions are still geared toward linux/ubuntu users. The ROSJava core documentation says: TODO: write a guide for a strictly java installation. I've tried to follow the instructions here on the Google Code project, but seeing as all the instructions assume I'm running

Qt binary linked to both Qt 5 and (wrongly) to Qt 4 causing segmentation fault when linked to Qwt

由 大兔子大兔子 提交于 2019-12-12 17:52:27
问题 I have a Qt / ROS / Qwt application. Everything was going fine until I tried to link to Qwt. Note that I'm using Qwt 6.1.2 which should run on Qt 5.5. Indeed, the examples run fine. When I run my binary, it crashes even if I'm not using Qwt. I just need to link the my code to Qwt for that to happen. And -here is the issue I think-, gdb gives the following error: ram received signal SIGSEGV, Segmentation fault. 0x00007ffff25eadfc in ?? () from /usr/lib/x86_64-linux-gnu/libQtGui.so.4 Which is

How to change directory of a library in a package in ros ubuntu

由 梦想与她 提交于 2019-12-12 17:10:33
问题 I have installed opencv2.4.9(With No CUDA) by unzip opencv2.4.9.zip in home. Many successful codes are using this library. Now I wanna rebuild opencv2.4.9(with CUDA) in another folder. I don't wanna delete the previous folder because I don't wanna face any problem later on and make my older code can't function. So, the question is how to change the name of the directory? Seems like we link the package with library in CMake like below: include_directories( ${catkin_INCLUDE_DIRS} ${OpenCV

问题 My problem is the following: I am using ROS and I am currently trying to read values from a PointCloud of a Kinect sensor. The values are of type PointCloud2 and PointCloud2.data holds the data of the PointCloud and is of type uint8[]. In my project I am currently using python and I have successfully registered and retrieved the data. My issue is that when trying to retrieve them python parses the uint8[] array as strings. The current part of the script where I have the problem is the

问题 I tried running the following command using subprocess.Popen() : ros_version_retrieve = subprocess.Popen(["rosversion", "-d"], shell=False, stdout=subprocess.PIPE) ros_version_retrieve.wait() rosversion is part of ROS and allows retrieving either the version of a given package by calling rosversion <package> or the version of the version of the installed ROS by calling rosversion -d . In the first case I will get a string like 1.12.3 and in the second I get kinetic (since that is the release
