calc_grasppoints_action_server.cpp integral not declared

[alex07zzz]

I was following the tutorial on ROS and when I catkin_make the package, there is an error in calc_grasppoints_action_server.cpp, line 592: 'integral' was not declared.

Did I miss something?

[davidfischinger]

"integral" is part of opencv (opencv2). Is opencv installed? In earlier ROS versions this was done automatically. Which ROS version is installed?

I am using ROS kinetic and Opencv has not been installed yet. Thank you so much for your answer.

Hey, is it compatible with opencv3? I am using kinetic as well but got the same error, guess my CMakeLists has not the right configuration...

Hi Belidan, sorry for the slow response. Could you solve the issue in the meantime? Regards, David Dr. David Fischinger Leithastraße 16/45 1200 Wien Tel.: +43 650 4109097 [email protected] <[email protected]> 2018-06-18 15:34 GMT+02:00 Belidan <[email protected]>:

Hi Belidan, maybe this conversation with *Amarnath* may help you. I think I did not test it with OpenCV3, and in the newest version of my company the OpenCV part was completely reimplemented from scratch, and hence the dependency is not needed anymore: * Amarnath Reddy: *

*Hi David,I proceeded further even after warning message from libsvm compilation.when I have done catkin_make to build haf_grasping I have got following error./home/amarnath/catkin_ws/src/haf_grasping/src/calc_grasppoints_action_server.cpp: In member function ‘void CCalc_Grasppoints::calc_intimage(int, int)’:/home/amarnath/catkin_ws/src/haf_grasping/src/calc_grasppoints_action_server.cpp:592:49: error: ‘integral’ was not declared in this scope integral(cvheightsmat, heightsIntegral,CV_64FC1)Can you suggest me how to overcome this?Thanks&Regards,Amarnath.* *David Fischinger, 15. Apr. Hi Amarnath ,there seems to be an issue with a dependency for OpenCV.The function *integral* is from OpenCV. So try to check if opencv in installed and the dependency is set accordingly.Regards,David* *Amarnath Reddy,15. Apr. an michHi David,I have already installed opencv3 in ROS kinetic after going through the comment made by you on the issue opened in Github.(#6 <#6>).Even after that I am getting same error.I think I have to change dependencies in CMakeLists. I have installed image_geometry,cv_bridge and opencv3 through binaries.Can you please suggest me which part I should edit? CMakeLists.txt is attached herewith .Thanks in advance and sorry for inconvenience.Regards.* *David Fischinger, 19. Apr. Hi Amarnath,I am not sure. Could you solve the problem inbetween?Could you test if OpenCV is really found?Maybe a configuration/path is not set?Regards,David* *Amarnath Reddy, 20. Apr.Hi David,I was able to build the package successfully.I had to append openCV include directories to include directories tag in CMakeLists and opencv2/opencv.hpp header file in action server source code.When i tried to launch the package with "roslaunch haf_grasping haf_grasping_all.launch", I am getting following error:process[rviz-1]: started with pid [20555]terminate called after throwing an instance of 'pluginlib::CreateClassException' what(): MultiLibraryClassLoader: Could not create class of type rviz::MONO8PCTransformerCan you let me know the way forward?Thanks in Advance.Regards,Amarnath.* *David Fischinger, 21. Apr. Hi Amarnath ,looks to me like a more general (not HAF specific) issue. Does rviz run if you only start rviz?* *Amarnath Reddy, 21. Apr. Hi David,I have later found that it is an issue with rviz due to ros update I have done to install open CV. I have opened an issue in ros-visualization repo regarding that.Without rviz haf_grasping is working fine and grasp positions are displayed in terminal,when I tested with the sample .pcd file in the repo.Thanks for the assistance.Regards,Amarnath.Regards,Amarnath.* *David Fischinger, 22. Apr. Hi Amarnath ,I am happy to hear that. Thank you for reporting my your solution(s).Kind regards,David*

Ahh thank you for the conversation. It really helped me out. The information to add the header file to the action server source code was very helpful. now its working fine :)
Kind Regards, Dimitrij

[davidfischinger]

Hi Dimitrij, you can do it like this:

> rosservice call /haf_grasping/set_grasp_center "graspsearchcenter: x: 0.10 y: 0.0 z: 0.0"

This sets the center point of the area where a grasp is searched. You can also define the size of the area around this point. (See chapter 3.2 here: http://wiki.ros.org/haf_grasping) Regards, David Dr. David Fischinger Leithastraße 16/45 1200 Wien Tel.: +43 650 4109097 [email protected] <[email protected]> 2018-06-25 12:24 GMT+02:00 Belidan <[email protected]>:
