Mapping change using 3D point clouds

The presentation presents the point clouds as remote sensing data for change detection. Indeed, the earth's surface is continuously changing either rapidly or slowly depending on the event. Each of these events has a defined magnitude, velocity, and frequency which determines whether the change is short-term or long-term. By reading this presentation you will discover the following points:
The importance of 3d for change detection, given that objects on the earth's surface have a large vertical component;
The challenges related to the use of this type of data for this specific task;
the existing methods (standard, and learning-based)
And our innovative research on this topic.
