Title: Improvements in the integration of lidar and photogrammetric datasets by in situ camera calibration
Abstract: Photogrammetric and Lidar datasets should be in the same mapping frame to be applied together in an engineering project. Nowadays direct sensor orientation is a common procedure used in simultaneous photogrammetric and Lidar surveys. Although the direct sensor orientation technologies provide a high degree of automation process due to the GNSS/INS technologies, the accuracies of the obtained results are dependent on the quality of a group of parameters that models accurately the user conditions of the system at the moment the job is performed. In this study, the in situ camera calibration is used to increase the accuracies of integration of photogrammetric and Lidar datasets considering the Lidar dataset as the base of reference control. The horizontal and vertical accuracies of 3D photogrammetric intersection were improved when Interior Orientation Parameter (IOP) under operational condition were used.
