Assessment on Different Digital Camera Calibration Software for Photogrammetric Applications

Abstract

Camera calibration has always been an essential component in photogrammetric measurement. Nowadays, self-calibration is being integral and routinely applied operations within photogrammetric triangulation, especially in high accuracy close range measurement. This study is to compare the accuracy of different types of software in order to determine the correct technique based on two different calibrations software. The objective of this study is to analyze the accuracy based on different resolution, to assess the calibration result based on two different software and to evaluate the best technique in camera calibration. Based on this study, the data involves are image of calibration sheet from different camera resolutions, good and bad light conditions and different flash conditions. This is the three types of data needed in this study before next process can be done. After all the data has been acquired, it undergoes data processing to assess the RMSE value for each result. This process used PhotoModeler software and GML C++ Camera Calibration Toolbox. The result shows the Olympus camera has better result than the other two camera used. In conclusion, the self–calibration method is easy to perform and save time compare to other method that required cost and more complex.
