3D urban object change detection from aerial and terrestrial point clouds: A review

Wen Xiao, Hui Cao, Miao Tang, Zhenchao Zhang, Nengcheng Chen

Abstract: Highlights•In-depth review of change detection of four objects-of-interest in the urban environment.•Analyse data sources used for different objects and summarise related public data.•Evaluate the methods in detail at pixel, point, voxel, segment and object levels.•Discuss the challenges and opportunities in 3D change detection for future studies.
