Gunho Sohn
I am Dr. Gunho Sohn, an Associate Professor of Geomatics Engineering at the Lassonde School of Engineering, York University. Currently, I serve as the Chair of the Department of Earth & Space Science & Engineering. :contentReference[oaicite:0]{index=0}
My research focuses on 3D urban space modeling and augmentation, photogrammetric computer vision, geometric remote sensing, web and wireless GIS, and building information modeling. :contentReference[oaicite:1]{index=1} I lead the Applied Urban Spatial Modelling (AUSM) Lab, where we develop innovative solutions to represent, describe, and understand urban environments through visual and spatial data. :contentReference[oaicite:2]{index=2}
I have been instrumental in projects like the 3D Mobile Mapping AI (3DMMAI) Project, a collaborative research program supported by Teledyne Optech, aimed at advancing 3D semantic mapping and SLAM using mobile lidar point clouds and images. :contentReference[oaicite:3]{index=3}

ISSUM Project Description
Landmine detection using polarized camera
This research leverages polarized imaging for landmine detection, capturing light at multiple angles (0°, 45°, 90°, 135°) and full-light images. Polarization features reveal surface anomalies and material differences, which are analyzed using advanced computer vision techniques. This approach improves detection rates, reduces false positives, and enhances safety in demining operations.
