Change detection is an important step for the characterization of object dynamics at the earth’s surface. In multi-temporal point clouds, the main challenge is to detect true changes at different granularities in a scene subject to significant noise and occlusion. To better understand new research perspectives in this field, a deep review of recent advances in 3D change detection methods is needed. To this end, we present a comprehensive review of the state of the art of 3D change detection approaches, mainly those using 3D point clouds. We review standard methods and recent advances in the use of machine and deep learning for change detection. In addition, the paper presents a summary of 3D point cloud benchmark datasets from different sensors (aerial, mobile, and static), together with associated information. We also investigate representative evaluation metrics for this task. To finish, we present open questions and research perspectives. By reviewing the relevant papers in the field, we highlight the potential of bi- and multi-temporal point clouds for better monitoring analysis for various applications.

“…Whereas, the predefined LCLU categories are more diverse for SCD. For example, the SEmantic Change detectiON Dataset (SEC-OND) [5] includes LCLU categories: "non-vegetated ground surface," "tree," "low vegetation," "water," "buildings," and "playgrounds." The Landsat-SCD dataset [6] includes LCLU categories: "farmland," "desert," "building," and "water."…”
