AN ITERATIVE APPROACH FOR SELF-CALIBRATING BUNDLE ADJUSTMENT

Accuracy Assessment of Commercial Self- Calibrating Bundle Adjustment Routines Applied to Archival Aerial Photography

The use of archival or historical photography for photogrammetric purposes often involves a lack of data concerning the aerial cameras employed, difficulties in identifying control points on the photos and inappropriate conservation of the photography. When camera calibration parameters are unknown, they should be estimated by means of a self-calibrating bundle adjustment. Several calibration m...

Calibrating a Multi-arm Multi-sensor Robot: A Bundle Adjustment Approach

Complex robots with multiple arms and sensors need good calibration to perform precise tasks in unstructured environments. The sensors must be calibrated both to the manipulators and to each other, since fused sensor data is often needed. We propose an extendable framework that combines measurements from the robot’s various sensors (proprioceptive and external) to calibrate the robot’s joint of...

Bundle Adjustment for Stereoscopic 3D

The recent resurgence of stereoscopic 3D films has triggered a high demand for post-processing tools for stereoscopic image sequences. Camera motion estimation, also known as structure-from-motion (SfM) or match-moving, is an essential step in the post-processing pipeline. In order to ensure a high accuracy of the estimated camera parameters, a bundle adjustment algorithm should be employed. We...

Is Case-Mix Adjustment Necessary for an Expanded Dialysis Bundle?

Congress has required CMS to expand the Medicare outpatient prospective payment system (PPS) for dialysis services to include as many drugs and diagnostic procedures provided to end stage renal disease (ESRD) patients as possible. One important implementation question is whether dialysis facility case mix should be reflected in payment. We use fiscal year (FY) 2000 cost report and patient billi...
