Intelligent Navigation and Mapping Lab

platform2.jpeg

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 20, 2025 We are excited to welcome our 2025 summer research students to the Intelligent Navigation and Mapping Lab. This summer, ten students have joined us to contribute to projects in smartphone navigation, SLAM, IMU stochastic modeling, ML based fall detection, diffusion and Gaussian Splatting, and end-to-end self-driving. Roy, Chan, Carter, Dennis, Raymond, Trevor, Kartik, and Sahat are supported through programs such as the NSERC Undergraduate Student Research Award, Mitacs, the Schulich School of Engineering, and other internal initiatives. We are also joined by two enthusiastic high school researchers—Jerry and Stephanie—who are gaining early research exposure through hands-on work with our team. We look forward to an exciting and productive summer!
Dec 16, 2024 Year-end Group Dinner at Happy Lamb Hot Pot! We had a wonderful afternoon celebrating the achievements of the year with great food and even better company. This year, we were joined by new faces: Ananya (not in the picture due to travelling), Paul, Shichuang, and Daiwuran, who have brought fresh perspectives and energy to the group. A special shout-out to Shuai, who was the MVP of the buffet today! Here’s to a productive and exciting new year ahead.
Oct 04, 2024 We were thrilled to welcome Li-Ta during his recent visit to our team. His presence provided an excellent opportunity to exchange ideas, discuss ongoing projects, and explore potential collaborations. As part of his visit, Li-Ta delivered insightful guest lectures, sharing his research journey and expertise. His engaging presentation captivated the team and students, sparking meaningful discussions that continued well beyond the lecture. We greatly value the knowledge and inspiration gained from his visit and look forward to future collaborations, building upon the strong connections established.
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!
