Issues with Leg_Tracker on Raspberry Pi 3 on ROS Kinetic (not Indigo) about leg_tracker

[mikaelarguedas]

Kinetic is using openCV 3.1. Having a quick look at openCV migration documentation it looks like the type CvRTrees is now named cv::ml::RTrees.
For future questions, please open an issue (like you did here) or ask on answers.ros.org but please do not write emails to ros-buildfarm-* mailing lists.

Mikaelarguedas, thank you for the reply.

We changed the code and then did catkin-make but still get same error as before. We are searching for a way to link opencv2.4 version to ros kinetic see if that would fix. Any suggestions?

Thanks!

Has anyone had any luck migrating this code to Open CV 3.1 to get it to run on ROS Kinetic? Or any suggestions on how to do this quickly?

Yes, OpenCV3 seems to be the problem. Ros Kinetic by default uses OpenCV3.

@candersen10 Yes, there is a way to use opencv 2.4 with ros kinetic. Please take a look at the ros packages opencv2_catkin.
(You might also need catkin_simple to get opencv_catkin running)

If you download it into the src folder of your workspace and run catkin_make, you get a local version of opencv inside your workspace.

To use it you have to add opencv2_catkin to the find_package(catkin .......) command in the CMakeLists.txt of the leg_tracker package and also add opencv2_catkin as a build and run rependency in the package.xml file.

I can confirm that the leg_tracker package builds with Opencv 2.4.13 (installed using opencv2_catkin) and Ros Kinetic on Ubuntu 16.04.

FYI, I think this should be resolved since ewerlopes migrated the repo to OpenCV3.
