In real_time_pose_estimation no errors but fails to detect the object

Question

I am working on real time pose estimation and you can find the code here https://github.com/opencv/opencv/tree/master/samples/cpp/tutorial_code/calib3d/real_time_pose_estimation (samples given in opencv 3.1.0).

It has two stages:

1. model registration(Registering the 3D textured model of the object to be detected in a .yml file)

2. model detection

   • if I send the .yml file(cookies_ORB.yml) which is already there in /real_time_pose_estimation/Data then detection is successful as expected

   • why its not detecting if I manually register the 3D textured model of the object in .yml file and ending with unexpected output .

This is what I do:

error

expected output-
