Object detection and 3D reconstruction with mobile mapping data

Semantic classification is a traditional research topic in both computer vision and remote sensing areas. With the development and common use of deep learning, image understanding gains relatively high accuracy and stability from big data, but still face challenges on accuracy promotion when processing the complex image scene such as city with high-density buildings, and on workflow simplification such as directly output of mapping results.

My current research focuses on automatic 3D reconstruction, semantic labeling and mapping with machine learning, which aims to make fully use of 3D information from stereo images and the power of AI. The research would help applications including earth surface surveying, city mapping and mobile sensing for autonomous driving.
