About

Ana Rita Gaspar is a robotics researcher whose work centers on visual odometry, SLAM (Simultaneous Localization and Mapping), and semantic perception for autonomous systems, with a particular focus on challenging underwater environments. Her most cited work, the Urban@CRAS dataset (18 citations), provides a critical benchmark for evaluating visual odometry and SLAM techniques, establishing a standard for comparing algorithmic performance in real-world scenarios. Gaspar’s contributions extend to underwater robotics, where she has developed methods for occupancy grid mapping from 2D SONAR data and semantic segmentation of harbour infrastructures—both essential for enabling robots to perform inspection, monitoring, and manipulation tasks in murky, unstructured subsea conditions. Her research on critical object recognition and place recognition using bags of binary words addresses fundamental challenges in autonomous navigation: robustly identifying landmarks and compensating for positional drift in dynamic, unknown spaces. By creating specialized datasets and comparative studies, Gaspar provides the tools and evaluations that allow other researchers to advance the state of the art in robot perception, bridging the gap between laboratory algorithms and real-world deployment in some of the most difficult environments on Earth.
