when i run scene reconstruction example it gives wrong set of points when i checked my openCL comparability i found that my laptop doesnt support openCL, could this be the problem for the wrong 3d points ?

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 ?
