[ahundt]

try installing the latest version of cmake

[blairlpp]

Thanks for ur help. I can succefully build the executable called extrinsic calibration and infrastructure-based calibration. But how to use the two exe? Hope for ur reply. @ahundt

[ahundt]

That I don't know, sorry! I've only done hand eye calibration with this code base. :-)

[evinpinar]

There are not any bin files after the cmake. What might be the problem?

[ahundt]

@epinar cmake just generates build files. Did you also make install?
