Hello, can you run OMD demo？ I faced some problems:
OpenCV Error: Assertion failed (npoints >= 4 && npoints == std::max(ipoints.checkVector(2, 5), ipoints.checkVector(2, 6))) in solvePnPRansac, file /tmp/binarydeb/ros-kinetic-opencv3-3.3.1/modules/calib3d/src/solvepnp.cpp, line 253
terminate called after throwing an instance of 'cv::Exception'
what(): /tmp/binarydeb/ros-kinetic-opencv3-3.3.1/modules/calib3d/src/solvepnp.cpp:253: error: (-215) npoints >= 4 && npoints == std::max(ipoints.checkVector(2, 5), ipoints.checkVector(2, 6)) in function solvePnPRansac
It seems like the problem of pnp-method. In fact, I found that it is caused by the few keypoints(only 2-5) in keypoints extract. In addition, not only did I have this problem:
