Bundle adjustment failed." #46

Hello, royshil, I completely run out of your program, but during the running process, the cmd interface prompts me, "Bundle adjustment failed", I have found the source of this sentence, in the file SfMBundleAdjustmentUtils.cpp, Lines 182-185, as follows

if (not (summary.termination_type == ceres::CONVERGENCE)) { cerr << "Bundle adjustment failed." << endl; return; }

Does this situation mean that the program has an error? How should I solve it?

I have the same question. I can't find any information about what to do when BA failed. Hope someone can help.

---- update--- I debug the program and found that most match was wrong , and I changed some set of the ORB, then it works.so when the it's not convergence, you can check the match. hope that can help you.
