ZED2 is not capable to track AR tags with zed_ar_track_alvar #13

Closed LucaRoma97 closed 4 years ago

Hi everyone! I'm working on my thesis about an autonomous charging system. I bought a ZED2 camera and a Jetson Nano. After having installed the SDK of the ZED and ROS (Melodic version), I cloned both the zed-ros-examples () and zed-ros-wrapper (.) I also change the zed_wrapper .launch file inside the zed_ar_track_alvar.launch (zed2.launch in place of zed_camera.launch). But when I try to launch the zed_ar_track_alvar.launch, the Rviz visualizations show me warnings and errors and I can't see the output of the camera. first_rvizz If I try to visualize the _rqtgraph: rqt_graph1 Then, I tried to change the Image Topic of Left Image, Left Camera and Tags ,as shown below: second_rvizz Now I can visualize the output of the camera, but it is not yet capable to track the ar codes and the rqt_graph now is the following: rqt_graph2 It seems that the node zed_ar_track_alvar doesn't communicate with the camera ones. I tried to change several names to the topics without any results. Someone has some advices for tracking the ar tags? Thank you in advance.

I've just fixed the Camera model error, but it still doesn't work.
