个人简介：
Dr. Yan Xia is now a Postdoctoral Researcher in the Chair of Computer Vision and Artificial Intelligence at Technical University of Munich (TUM), working with Prof. Daniel Cremers (Gottfried Wilhelm Leibniz-Prize Winner) on advancing 3D scene understanding. He is also an associate member of Munich Center for Machine Learning. He has served as secretary of Working Group I/8 International Society of Photogrammetry and Remote Sensing (ISPRS). He obtained his PhD degree from TUM in 2023 and was a visiting scholar in Visual Geometry Group (VGG) at University of Oxford. His research interests include 3D vision, robotics, and autonomous driving. He has published 20 academic papers at top-tier conferences and journals such as CVPR, ICCV and ISPRS Journal. He received the Best Paper Award at the ISPRS Geospatial Week 2023.
报告摘要：
Localization is a critical capability for self-driving vehicles, allowing them to pinpoint their location on a map. The well-known technique for localization is to use global navigation satellite system (GNSS). However, the signals of satellites are bound to fail among tall buildings and vegetation. As a result, sensor-based solutions can be decisive in improving the localization. In my research, I develop a series of 3D visual localization methods, aiming to enhance localization accuracy and generalizability in GNSS-denied environments. In this talk, I will specifically highlight several of my recent papers. These include studies on point cloud based place recognition [1][2] and cross-model localization methods [3].
