Simultaneous Localization And Mapping (SLAM) is a fundamental problem in mobile robotics. Semantic SLAM is an effort to build meaningful map representations that not only provide rich information about the environment but also aid in camera localization. This work proposes a method for representing generic objects using quadrics that allows seamless integration in a SLAM framework, with additional dominant planar structure modeled as infinite planes. Experiments show the proposed points-planes-quadrics representation can easily incorporate Manhattan and object affordance constraints, greatly improving camera localization and leading to semantically meaningful maps.
