Abstract
A markerless augmented reality (AR) can track 2D feature points among video frames, generate 2D point clouds and 3D point clouds based thereon, and match a 3D model against 3D point cloud to obtain proper positional information of the model with respect to a frame. The AR system can use the 3D model with the obtained positional information to render and project AR content to a user's view. Additionally, the AR system can maintain associations between frames and 3D model positional information for search and retrieval.
