Hi WeiyiLi - thanks for reporting this issue! I think you struggle (same as I did) with problem referred here: http://www.pcl-users.org/Using-non-C-11-PCL-in-C-11-project-td4036998.html. So I would recommend to checkout-build-install latest PCL build. FYI I'm using PCL ref: e6e986d6b3330a8d765f9bd0cc3f6eae8cdcdd80, ubuntu 14.04 and ROS hydro Hope it helps, Martin. |

@martin-velas Thank you very much! The link you provided helps me fix the error and it doesn't terminate. However, it stops (not terminate) at "process[calibration_coarse-1]: started with pid [8828]" after I run the program with an usb camera and Velodyne. I wait for minutes but there is no more outputs...I am not sure whether the program is running during this period.. It might be stuck in code "sync.registerCallback(boost::bind(&callback, _1, _2, _3));", which is in main class of calibration-node.cpp because I put three "cout" before and after this sentence, and at beginning of callback function. Only the "cout" before this sentence prints something. Do you know why the program pauses at this moment? And is there any way to visualize the processing? I opened rviz after I run the program but it shows nothing....Thx for your help again! :) |

First of all - make sure, that the sensory data are propagated into the proper topics. You can list the topics by Cheers, M. |

@martin-velas As you said, I checked the topics and finally found out the problem and make it running! Thank you very much! For the configuration file, can I know what is the unit for circles distance and circles radius? Meter or feet? |

Hello @WeiyiLi , Could you please let me know how you solved your issue? I have checked the topics and changed the config file, but still face the same issue as you had mentioned before. |
Hi, when I tried to roslaunch calibration calibration_coarse.launch with valgrind, I got the following error and the process died. I tried to google the problem. One solution is to remove "-std=c++0x" from CMakeLists.txt but it doesn't work.
Since I am using Ubuntu 14.04, I used ROS Indigo instead of hydro. The version of pcl is 1.7. I also downloaded 1.7.1 and change CMakeLists.txt from "find_package(PCL 1.7 REQUIRED) " to find_package(PCL 1.7.1 REQUIRED) but it doesn't solve my problem.
The error is shown below,
