您好，我会有以下问题，请问一下应该是什么么原因呢

Please, can you provide some context about your compiler and platform?

• As an alternative you can use the version implemented in OpenMVG https://github.com/openMVG/openMVG/tree/master/src/openMVG/matching/kvld This version is tested under various compiler and platform.

Thank you for your reply.I use it on VS2012,But there are still problems.I will try OpenMVG.Thankyou

I will also make a lite version, which may solve the problem.
