when i use sfm::reconstruct to extract the point cloud out of set of images it gives faulty 3D points (i already calibrated my camera and found the camera matrix) could the images be the problem and if so what should be done ?

edit

How many images have you got in the set ?

6 images..

can you try with images here?

thank you so much i will try with them and then tell you the results

still the same problem could be a problem with the build of the library ?! it should give me a point cloud representing the scene , isnt it !? or there is something i miss understand ?

i build ceres without SuiteSparse , would that be the problem !?

I don't think so. Have yo run sample example_sfm_scene_reconstruction.exe ?

How to build sfm using cmake and my getbuilinformation it's here

i didnt build the examples i will build it again and build examples and show you my build information

thank you so much for your concern i really appreciate it

here are my build informationhere

when i run the example it gives me this errors ERROR: In e:\library\vtk\vtk-8.1.1\rendering\opengl2\vtkwin32openglrenderwindow.cxx, line 685 vtkWin32OpenGLRenderWindow (000001C8D871B360): failed to get wglChoosePixelFormatARB

Sorry for delay. I think error given is a problem with vtk lib mixed release and debug (you cannot run vtk with opencv releaese and debug you have to choose)

it is okay so i have to build vtk lib only with debug or release(lets say release ) then build opencv in release ?

Yes release with release

okay i will do so and tell you the updates thank you so much

iam really sorry for bothering you but there is still no resuts here is sample of my code and here are the results i would really appreciate it if you would check them for me and thank you in advance
