Description
Summary:Representing the world using sparse objects allows for compact and semantically meaningful maps in simultaneous localization and mapping (SLAM). Traditionally, object detectors trained on a specific set of objects, such as the YCB objects, are used to provide input to the data association problem, which limits the scope of the system to environments that it has been trained on. With advancements in foundational models, we can extend this representation for objects that are not known a priori and do not have a labeled category during training. This thesis explores a system that creates data associations between open-set objects using an RGB-D camera and how it is used in a sparse object SLAM system. We show comparable trajectory performance to traditional SLAM systems while being more adaptable to out-of-distribution objects.
