Only one tag size for pose estimation #5

Open cikn97 opened 2 years ago

Hello, thanks again for your package. I have a question regarding the use. In the launch file only a single tag size can be given. As far as I can tell from the apriltag3_ros.cpp file (and the output) the given size is used to calculate the tag pose, is this correct? If so then I wonder how tags of different sizes are used, for example during the camera/lidar calibration. The Tag detection isn't affected by this, however if the tags are of different size only the pose estimation of one tag can be correct. In the original apriltag_ros package multiple sizes can be given, however it returns only the pose, not the corresponding tag corners used in the calibration. I would be grateful if you could give some insight on this. Thanks again!
