Camera/IMU Boresight Calibration: New Advances and Performance Analysis

TM software of Applanix Corporation. First, a brief discussion is presented to summarize the software capabilities in a descriptive fashion. Then, a number of analytical tools implemented in the software, which are needed to do quality assurance and quality control of the GPS, IMU, image, ground control, and datum issues, are briefly introduced. An analytical study has been done to test the analytical tools of the software. This study has been done using real sets of data collected by HJW GeoSpatial Inc of Oakland California, and by the pilot centre (University of Hannover) of the European Organization for Experimental Photogrammetric Research (OEEPE). All data sets were acquired by a 9” x 9” film camera equipped by a 6” lens cone and by Applanix POS/AV TM 510 system. In addition, all data sets had a good number, distribution, and accuracy of ground control points, quality image measurements, and good GPS and IMU data. This allowed starting off with good quality data sets where biases and noises were introduced intentionally for analysis purposes. Different imaging configurations have been studied. All data sets have been run with and without ground control points where their effect is analysed. A summary of the results and analysis is presented together with the relevant references that discussed this topic.
