City-scale Scene Change Detection using Point Clouds
Zi Jian Yew Gim Hee Lee Zi Jian Yew Gim Hee Lee
We propose a method for detecting structural changes in a city using images captured from vehicular mounted cameras over traversals at two different times. We first generate 3D point clouds for each traversal from the images and approximate GNSS/INS readings using Structure-from-Motion (SfM). A direct comparison of the two point clouds for change detection is not ideal due to inaccurate geo-locati...
