Intelligent Navigation and Mapping Lab

The Intelligent Navigation and Mapping Lab is led by Dr. Hongzhou Yang at the University of Calgary, specializes in developing advanced navigation and mapping technologies for autonomous systems through sensor integration and machine learning. The lab integrates multiple sensors, including GNSS, IMU, camera, LiDAR, radar, and odometer, to provide reliable and precise navigation and mapping solutions. Machine learning algorithms are also employed to enhance these systems, ensuring scalability and efficiency in autonomous navigation and mapping technologies.

Jul 08, 2024	We are excited to share that Louise, Favour, and Rebekah have already joined our research group this summer. Louise is visiting us from Hong Kong PolyU with the UG Summer Research Abroad Sponsorship (USRA), while Favour and Rebekah have joined funded by the Women in Science and Engineering (WISE) project. Additionally, earlier this summer, three more research students—Raymond, Bosco, and Trevor—joined our group. Raymond and Bosco are recipients of the NSERC Undergraduate Student Research Award, and Trevor is funded through SSE.
Jul 03, 2024	Congratulations to Qiaozhuang! His latest paper “Credible positioning of BDS RTK/INS integration based on multi-information cross-validation” was accepted by the IEEE Transactions on Intelligent Transportation Systems, cheers!
Jun 16, 2024	The data collection platform is ready for the first road test with multiple sensors onboard, including the GNSS, IMU, camera, LiDAR and MCU.
