Abstract
In this paper, we present a client-server system for 3D scene change detection. A 3D scene point cloud which stored on the server is reconstructed by (structure-from-motion) SfM technique in advance. On the other hand, the client system in tablets captures query images and sent them to the server to estimate the change area. In order to find region of change, an existing change detection method has been applied into our system. Then the server sends detection result image back to mobile device and visualize it. The result of system test shows that the system could detect change cor- rectly.

Summary
Recent surveillance technology developments motivate a regular observation of places such as coast, slopes and highways, where disasters and accidents happened with high probability. A lot of wave dissipating blocks are placed to decrease the power of waves. A 3D scene change detection system will be helpful to defend disasters and accidents. Since a variety of mobile devices are much cheaper and more powerful than before, a 3D scene change detection system on a mobile platform is possible to be implemented. We present a system that is capable of detecting 3D scene change based on query image provided by a mobile platform. Image acquisition is performed on a mobile device, and only selected key frames are sent to a powerful server for change detection.
