Paper Abstract

The Air Force Research Lab, Advanced Guidance Division, AFRL/MNG located at Eglin AFB has expanded the capabilities of its Modular Algorithm Concept Evaluation Tool (MACET) for autonomous target acquisition (ATA) analysis to include an imagery truth editor for simultaneously displaying and working with multiple images of differing dimensionality and resolution. To support multi-sensor truthing, the MACET Truth Editor performs computer-assisted geo-spatial registration between multiple 2D images, or between 2D images and 3D images. The input images of overlapping scenes may be obtained from various sensor types (visible, passive infrared, laser radar (ladar), etc.) and taken at different sensor locations and orientations. Registration of 3D to 2D and 2D to 2D imagery pixels is made to a reference 3D coordinate system using `hints' provided by an analyst. Hints may include some combinations of the following to reach an approximate solution to the registration problem: marking of common points in each image, marking of horizon lines in 2D images, entry of imagery sensor characteristics (FOV, FPA layout, etc.), and entry of relative sensor location and orientation. The MACET Truth Editor has a consistent user interface that allows registration hints to be entered and truthing operations to be performed graphically.
