Corrected pose data for the Wright Patterson Air Force Base 2009 Wide Area Motion Imagery data set

摘要

The Wright Patterson Air Force Base 2009 Wide Area Image data set consists of 1537 frames of high-resolution image data. The data are supplied as raw images with pose files and also as projected images in National Imagery Transmission Format (NITF). The georegistration performance of the NITF images is 22.3 m root-mean square horizontal (RMSH). In a previous paper, calibrated camera models were developed to reduce the georegistration error to 3.3 m RMSH. In this work, corrected pose files are generated to reduce the error to 0.9 m RMSH. This is done by correcting the pose errors in a stepwise fashion to illustrate the error sources, which are global positioning system position bias, time registration errors, and attitude errors. The pose files are then corrected by simultaneously modifying the position and attitude to achieve the 0.9 m RMSH result. The corrected pose files are posted to allow users to perform high-accuracy projection, tracking, and other functions. (C) 2015 Society of Photo-Optical Instrumentation Engineers (SPIE)
