Hi guys, I'm looking to use the confidence value as well, did you manage to solve this issue? Saito . My approach is to do the checking in the code I write. I have tracked down the issue and fixed this locally for individual markers by changing a few lines of code in **nodes/InvididualMarkersNoKinect.cpp**. The machinekoder repo almost works well, however, if you look at some comments on this (unrelated) issue machinekoder#1 , you will notice that there is a problem where nan is published for a lot of the results. If you build it from source it should work on Indigo without a problem.

Here are the classes, structs, unions and interfaces with brief descriptions: There is quite some potential of reworking parts of the code aside from the port. Older. sign in Repos. ar_track_alvar has 4 main functionalities: Generating AR tags of varying size, resolution, and data/ID encoding. Reading package lists. To use the camera, we need to install the right drivers: # web cam driver sudo apt-get install ros-kinetic-usb-cam # Kinect driver sudo apt-get install ros-kinetic-freenect-launch Run the usb camera: I will start working on this next week. So conversion to the C++ is needed along the CV3CV4 port which is small. Work fast with our official CLI. How are you installing ar_pose?

I checked the parameters in rosrun rqt_reconfigure rqt_reconfigure and they are all the same either with the zed parameters and ar_track_alvar parameters. Would you mind releasing ar_track_alvar to ROS Noetic? The reason I need the confidence is so that could set a confidence threshold and reject those detected tags which have a lower confidence value than the threshold. @sniekum are you still involved? ar_track_alvar uses the long dead C API for OpenCV. @chriskeraly-rios @machinekoder are either of you planning to make a noetic-devel PR? OS: ubuntu 20.04 Are you sure that the tags are printed correctly and they are placed on a perfectly planar surface? Done If I make the top tag as the master tag, I would like to get the pose estimates of say one of the tags on one of the sides. Although I am able to detect the tags, when I print the ID and the confidence, I get the confidence value to be always zero. Sorry for beginner question, Turns out porting is not as easy as first thought. But the tag detections are not accurate and its too noisy. Turns out porting is not as easy as first thought. There is quite a lot cv code in there that needs to be translated. My Labmate uses ROS melodic (ubuntu 18) and his detections are far more accurate than mine (same situation). Issue : I have compiled opencv 4.1.0 with cuda support. Moreover, there has been a deprecation of some Eigen types in noetic, which we have to keep in mind, but nothing significant either.
