In reply to Bulduk. I have no idea what you mean by "greater marker," as there's no such reference in the Pi-Tag paper.

Hi, thank you very much for this Information.

I use this Tags for my bachelor thesis. There I have to use greater Marker. Therefore I have to modify the params to detect this greater pi-Tags. But the algorithm still not detects the greater Marker.
What would be your advice?

Thank you

In reply to Manh-Ha Hoang. The markers/tag0.xml file in the repository is an example model file. Any of the other model files from cobs_fiducials work as well.

In reply to Matthew Petroff. I found the problem. It is the pointer shared_ptr. I need add SET(CMAKE_CXX_FLAGS "-std=c++0x") in cmake in order to run the code. The test program is ./pitag-test modelfile imagefile. I know the image file is tag images, but how about the format of modelfile? Is it .xml file?. Can you upload the file sample? Thank you :)

In reply to Ha. Is there an error? cmake builds the program but does not run it. I would highly recommend doing this on Linux, and you need to make sure the dependencies listed in the readme are installed. Details for using the test program are also included in the readme.
