Projection-based Augmented Reality

How I can access a projector and project edge lines around the aruco marker using that projector.

what I have done so far:

  1. Successfully completed the aruco marker detection and draw edge lines around the markers using the following tutorial and the output is like this image.

  2. Completed the projector-camera calibration and computed the extrinsic parameters: rotation matrix, translation matrix, and intrinsic matrix. Now I can map a point from the camera coordinate system to the projector coordinate system. I used [singleprocamlib] to perform this calibration.

Now I want to project detected edge lines around the aruco marker using the projector.

Sorry in advance if I ask a very noob question. Please comment and share if you have any suggestions, resources regarding my problem.
