Have you solved the problem? Now I face the same situation.

[atangger]

you may add a line: #include<fstream> in the SfM.cpp and it will be fine.

[YuehChuan]

@atangger tricks work form me
ubuntu16.04.5
ROS kinetic
also you will get BOOST version error

in SfmUnitTest.cpp raw 45 ' #define BOOST_TEST_EQUALS'
modified
BOOST_TEST to BOOST_TEST_MESSAGE

example
#define BOOST_TEST_EQUALS(a, b, e) BOOST_TEST_MESSAGE((((a) == (b)) || (std::abs((a) - (b)) < e)))

then compile 100%

./build/SfMToyUI dataset/crazyhorse/
can run the demo but final result fail
visualize use meshlab

@YuehChuan hello,I am the same with you. And I change some other datasets, the result seems to be too sparse to recognize it, is there something wrong?

Excuse me, I am failed in that:

But I do not know why.

Hello,

i was able to get the demo running but i also got a very bad result. Did some one fixed it or have some ideas which settings in the ORB Detector can cause this problems?

Thanks in Advance
