摘要：Airborne intelligence, surveillance and reconnaissance (ISR) can provide essential information for both military and civilian applications. Such capabilities are critical for situa tional awareness, mapping and monitoring, and mission planning. UAVs gather large amounts of video data, but it is extremely labour - intensive for operators to analyse the hours and hours of data collected. At MDA, we have developed a suite of video explo itation tools to process UAV video data, including tools for mosaicking, change detection and 3D reconstruction. The main objec tive of this work is to improve the robustness of these tools, to integrate these tools within a standard GIS framework, to auto mate the tools, and to present these tools in user - friendly ways to operational users. Our mosaicking tool produce s a 2D map from the sequence of video frames contained in a video clip. For scene monitoring application s , our change detection tool ident ifies differences between two videos taken from two passes of the same terrain at different times. O ur 3D reconstruction tools create calibrated geo - referenced photo - realistic 3D models, which are useful for situational awareness. The semi - automated appr oach allows the user to create surfaces interactively by marking c orrespondences between frames, while t he automated approach gen erates 3D models automatically . MDA provides UAV services to the Canadian and A ustralian forces , offering important ISR infor m ation to front - line soldiers. Our suite of semi and fully automated video exploitation tools can aid the operators to analyse the huge amount of UAV video data to support battle - space mapping and monitoring applications
