Sensor Modeling and 3D Visualization

Abstract

Two related, but independent investigations were carried out under this project. The first related to sensor (camera) modeling as needed for the photogrammetric exploitation of imagery for mapping and geopositioning purposes. This task was further subdivided into two subtasks. The first of these involved performing a geometric camera calibration for a set of 4 co-boresighted video cameras (called CAMIS) used by TEC (Topographic Engineering Center) for remote sensing and mapping purposes. This involved setting up a laboratory calibration facility, collecting system imagery in that facility, developing software and algorithms to align the fixtures in the facility, and developing software and algorithms to perform the camera calibration. The second subtask was to investigate the detection of errors in aerial triangulation, motivated by recurrent problems using the SOCET SET triangulation module for large blocks of images The approach here was to implement and test two algorithms for such error detection in a prototype MATLAB GUI (graphical user interface) Testing showed that both algorithms had merit for the error blunder detection problem. The second task in the project was the further development of Vesper for the Battlespace (VFB) product. The goals here were to develop and demonstrate advanced sensor data fusion, 2D and 3D visualization capabilities, combine the visualization environment with precise geo-registration, creating a single, end-to-end data visualization system. This system enhances time critical operations such as intelligence gathering, mission planning and rehearsal, and operational command and control. Specific modules within VFB include auto geo-registration of EO,SAR,IR,HSI, and SIG data, sensor model update, sensor projectors, object models (DTED, etc.), and interactive 2D/3D visualization.
