Augmented Reality (AR) is the rendering of elements such as text, images, videos, 3D objects, etc into our real-world environment. In this paper, we have used this technology to bring a change in the vision of education (online mostly while staying remotely) to help students understand the concepts for example Engineering Mathematics, Electromagnetism, etc. by bringing 3D models of the concepts superimposed into the real world. The paper has been divided into two parts: The first part consists of the marker-based AR approach where an image target is brought in front of the camera to superimpose it with 3D model here. It consists of feature extraction, feature description and feature matching, homography, projection and bringing 3D object to scene. The second part is the development of an Android application using Marker less AR approach explaining an engineering concept. We have used 3D models and necessary UI elements. A comparison of both the parts of the work has been made.
