This is regarding the sample code shipped with opencv 'build3dmodel.cpp' https://code.ros.org/trac/opencv/browser/trunk/opencv/samples/cpp/build3dmodel.cpp?rev=3220 . I am hoping to do a project on 3d reconstruction using opencv, but before that i would love to test a sample project like this. I have configured OpenCV on Visual Studios 2010. I am new to OpenCV, Please do tell me how to give inputs( I have a test image set) to this programme to test ( specify the lines please..) this is a GREAT help!
