the collection of matched feature points

Hello

At present, I am making a simple application using Vuforia to place a cube on the identified image. As far as I know, Vuforia matches the feature points in the image database with the feature points recognized by the camera in real time. After matching enough feature points, the cube will be displayed. Now I need to find the collection of matched feature points for each frame to realize some new functions. Can you help me find the collection of matched feature points?

thank you very much indeed
